Do you want to get an accurate earthquake forecast?

Geophysicists have an understanding of the mechanism and causes of earthquakes in the contact zones of tectonic plates. Here, earthquakes occur as a result of the spreading of tectonic plates. Geophysicists have an understanding of the mechanism but not the causes of earthquakes in transform fault zones. Geophysicists have no understanding of either the mechanism or causes of earthquakes with epicenters inside tectonic plates. There is no understanding of the causes of repeated strong shocks. They are simply called foreshocks and aftershocks. about the cause of the aftershock of the Turkish earthquake, there is information in my discussion "The earthquake in Turkey is a consequence of planetary scale geodeformations. Is the concept of stress accumulation before an earthquake wrong?". The theory is in my discussion "Ocean tides and deformations of the Earth's surface of tidal origin have different physics of the process. Why?".

I will give the actual data on earthquakes with a magnitude of more than seven in Turkey on February 6, 2023. Data from open sources on the Internet.

Judging by the Moment tensor map data, both earthquakes had the same Focal_mechanism - Left-lateral strike-slip. The first shock was caused by a shift in direction southwest - northeast. The second shock is caused by a shift in the direction west - east. This was confirmed by the intensity maps of shaking from earthquakes.

With a vertical amplitude of semidiurnal tides in the solid body of the Earth from -13 to +23 cm cm during earthquakes, the indicated amplitudes of horizontal and vertical tidal displacements completely coincided. 12 hours after the aftershock, the amplitude of the vertical tidal displacement decreased only by 5% (it remained high).

Conclusion. While maintaining significant geodeformation energy throughout the whole day of February 6, which was caused by geodeformations on February 3 in changes in the gravitational field, the first earthquake significantly weakened (did not destroy) the tectonic structures of the Eastern Anatolian Fault (azimuth 45 degrees). The aftershock was inevitable. When the tide in the solid body of the Earth repeated itself in phase and amplitude, an aftershock occurred under conditions of powerful geodeformations on a planetary scale. By the second earthquake, the tectonic structures of the Eastern Anatolian Fault were destroyed and transformed into structures with an azimuth of 90 degrees. The third earthquake was already inexpedient, although at 10 pm on February 6 there was quite a lot of energy.

Note. The tides in the solid body of the Earth deform the planet along the parallels and meridians and all existing fault systems (azimuths 17, 35, 45, 62, 77 degrees) transform into a system of block divisibility of the lithosphere 90 degrees.

“You cannot predict [an earthquake] in the sense that there is no developed theory. There are many hypotheses, one might say, scientific ones, but these are still phenomenological models of earthquake preparation. On this basis, it is impossible to build an earthquake prediction system that would be comparable to, say, a weather forecast. This is one side of the matter - that there is no developed quantitative theory of preparation <...> In fact, the trouble with all the signs [of earthquakes] is that sometimes they are observed, but an earthquake does not occur. Which is just as bad as the fact that an earthquake occurs, but they are not observed. Why do I think the first one is very bad? Because false alarms that can spread in such a situation, and panic undermine confidence in this, as in some kind of serious matter, ”said Ruben Eduardovich.

Why does Tatevosyan lie so shamelessly?

If he does not agree with Rogozhin and Nikolaev, then let him prove it openly!

«Нельзя предвидеть [землетрясение] в том смысле, что не существует разработанной теории. Есть много гипотез, можно сказать, научных, но это все-таки феноменологические модели подготовки землетрясения. На этом основании нельзя построить систему прогноза землетрясения, которая была бы сопоставима, скажем, с прогнозом погоды. Это одна сторона дела – то, что нет разработанной количественной теории подготовки <…> На самом деле беда всех признаков [землетрясений] заключается в том, что иногда они наблюдаются, а землетрясение не происходит. Что так же плохо, как и то, что землетрясение происходит, а они не наблюдаются. Почему я первое считаю очень плохим? Потому что ложные тревоги, которые в такой ситуации могут распространяться, и паника подрывают доверие к этому, как к какому-то серьезному делу», – рассказал Рубен Эдуардович.

Зачем Татевосян так бессовестно лжет?

Если он не согласен с Рогожиным и Николаевым, то пусть докажет это открыто!

What broader implications could the adoption of the functional recovery design philosophy have for disaster preparedness and response strategies in urban planning and infrastructure development?

What are some key research directions suggested by the article for advancing the field of functional recovery in earthquake engineering?

I am an M.Tech structural engineering student working on the project ' Numerical analysis of Kath-kuni architecture ( a common masonry typology ) in Himachal Pradesh region of India subjected to earthquake loading in ABAQUS software' . The question of concern is that I am finding it difficult to input plasticity parameters for timber/ wood material that I have used in my model even after searching in various research papers. I have got only elasticity parameters and wood being an orthotropic material requires plasticity parameters and a plasticity damage model to be defined in order to understand the actual material behavior in ABAQUS software. So, kindly help me in finding the plastic properties and a damage model for timber, it would be very helpful to proceed in my current project.

Thanks and regards

Are there investors on the forum?

The theory of the Genesis of earthquakes has been created.

Based on this theory, the main fields, the main forces involved in the development of earthquakes, are determined.

The participation of the same fields in the creation of anomalies and in the creation of the earthquake itself ensures 100% reliability. The low speed of the wave that creates an earthquake ensures high accuracy in determining the location, start and end time, and the strength of a future earthquake.

This makes it possible to save people's lives.

This makes it possible to receive high income by reducing the losses of countries in earthquakes.

This gives sustainable growth through the development of the Global Earthquake Prediction Network.

I did everything I could. No one will ever exceed the number of positive opinions I have received.

It's not because I'm a "genius".

This is because there is no point in creating a collection of positive conclusions. I had to do this because I worked alone.

The institutions of Israel hated me because I am a "Russian Jew" who dared to create a patent.

The Academy of Russia hates me because the Expert Council of the RAS itself recognized my results and recommended starting implementation.

And now what? Everything you need has been created.

People will die in hundreds of thousands because no one wants to implement?

INVESTORS, AU,

DIRECTOR, AU.

Do you want to do something important and useful?

I'm 76 and oncology. Who wants to become a leader and get the knowledge that I have accumulated in 20 years?

I will participate in a conference on the effects of earthquakes and my study on the economic effects of the earthquake on the Syrian economy. I hope that you will share with me information about the economic effects of the earthquake on the economic sectors.

I need help modelling horizontal BNWF with axial, transverse, and vertical (bearing & uplift) springs and spring damper at the ends to simulate connectivity.

I want to know how I can model these on to the beam and assuming the pipeline segment is 1 kilometer in length, at what intervals should the soil springs be applied? Can we assign line springs in OpenSees?

Thank you

P.S I would like to validate my results through this paper "Seismic risk assessment of buried steel gas pipelines under seismic wave propagation based on fragility analysis - Vahid Jahangiri, Hamzeh Shakib" - DOI 10.1007/s10518-017-0260-1

One of the scientists states: “It is not easy to predict an earthquake, and so far there has not been a single successful prediction in history, except for one Chinese researcher in the mid-70s.

Those who can read Russian or English, I suggest that you read these documents carefully.

After that:

I ask the scientists of the world to inform: who else claims that the Genesis of earthquakes has not been discovered, that the short-term earthquake forecast has not been created and has not been tested?

Greetings from the world geophysics and seismology community I am searching to find a practical, and important topic for my Ph.D. thesis. Professors and those who view this post, if they are interested in doing joint international projects between the two countries, please share your topics and suggestions with me. I will write my favorite topics for you and if possible, I would like to know your opinions sincerely *Earthquake engineering and risk analysis **Application of seismology in oil exploration and extraction ***Data science and machine learning

Dear Professor Peng Chaoyong,

I ask you to inform: how many people died in this earthquake?

Can we relate the earthquake and mushroom diversity or mycorrhizal diversity? If yes, How?

Thank you.

What would happen if the Earth's axis changed and which earthquake shifted Earth off its axis?

Who is responsible for earthquake in India and what happens if the Earth's rotation reversed?

Can an earthquake shifted the Earth's axis and how many times has the Earth's axis changed?

I wonder when declustering a catalogue of earthquakes, does repeated event count as cluster or not. fo example when i am geting data from ISC, IRIS, and USGS for specific area considering time and magnitude, if I have an event with Mw=7.4 while making the catalogue in some chances maybe I get multiple events that have Mw=7.4 due to random institute data collection.

All in All for example I have multiple even with the same lat, lon, data, time, and magnitude but they are used to be one event. when declustering the catalogue does one event remains or all of them are counted as main events?

Thanks.

Dear All, I hope you can point me in the direction. I am interested in finding P-wave and S-wave velocities from earthquake data. However, I couldn't find any particular article or methodology explaining how I can get the P and S velocities from the Earthquake dataset. Looking forward to your suggestions...

Logical Algorithm for the operation of the tsunami warning system. First of all, the place and time of a strong sea earthquake is fixed and a decision is made that there is reason to worry about the formation of a tsunami. Secondly, anomalies in the measurement data of buoy stations of the DART system are studied (anomalies are selected automatically). If the station indicates that the wave height is significant, then an alarm is announced (usually the height of a tsunami in the ocean is up to 50 cm). Everything is simple and clear.

In fact, the DART system applies a different logic.

Let's look at the logic of DART after a strong earthquake in the Tonga region on May 10, 2023.

DART received information about a strong ocean earthquake. The picture is attached.

DART station #51425 (700 km from the epicenter) and a station in the Hawaiian Islands area automatically gave an alarm about unusual sea level fluctuations. They showed it on the official DART website. An anomaly 23 cm high was recorded at DART station No. 51425. I attached a general graph, its details. The table highlights the start time of the anomaly.

The text of the official announcement surprises. Quote: "EVALUATION - Based on the depth of the earthquake, a tsunami is not expected". The algorithm does not provide for the analysis of the depth of the earthquake, the depth of the ocean, tectonic features. This is an engineering, not a scientific system. Errors are not allowed here. Have you recorded a tsunami or not. There is no third.

The DART measurement system showed a “wave” 23 cm high, but gave no warning. This cannot be done. This will discredit the entire project.

In many of our scientific publications (for example, our book Volume 3. Previously unknown aspects of the formation of climate, weather, including natural hazards) and in discussions, I have pointed out the wrong decision-making procedure for declaring a tsunami alert.

Check out my discussions:

Tsunami waves and problems of early warning.

Why does everyone know that the physical model of tsunami generation is wrong, but they continue to use it and teach children?.

Is it possible to consider a tsunami wave as a Rayleigh wave?

What type of wave does the Deep-ocean Assessment and Reporting of Tsunamis (DART®) mistake for a tsunami?

DART gives false tsunami alerts to the public. What reason?

These discussions talk about the many erroneous decisions made to evacuate the population based on the results of DART. This resulted in large economic losses. But the most important thing is the discrediting of the most modern and expensive system of automatic fixation and early warning of the approach of a tsunami. The humanitarian mission of this system is enormous, given the casualties that usually accompany the arrival of a tsunami on the coast, especially in areas of active tourism business. It turned out that the reason for the unsuccessful organization of the global tsunami warning system was an elementary misunderstanding of both the physical nature of the tsunami and the simple, actually well-known, patterns of its propagation.

Look at the timing of the Tonga earthquake and the timing of the anomaly recorded by DART #51425. A tsunami wave cannot cover a distance of 700 km in 165 seconds. The tsunami speed is about 0.2 km/s, not 4,200 km/s.

It turns out that the nature of the measured anomaly at DART station No. 51425 is not a tsunami. Judging by the propagation speed, the recorded anomaly is the fluctuations of the seabed during the passage of the Rayleigh seismic wave.

Can the automatic sea level recorder (DART) distinguish between sea level changes associated with the passage of tsunami waves and sea floor oscillations during the passage of a seismic Rayleigh wave? The answer is it can't.

If the stations do not allow this, then in the DART tsunami warning centers this can be done simply by changing the decision-making algorithm. If the time of fixing the ocean level anomaly by the DART station coincides in time with the expected time of the tsunami approach from the earthquake epicenter, an alarm is announced. This is right?

DART doesn't know about it.

I will repeat the simple algorithm once again. There are approximately 700 km between the epicenter of the earthquake and DART station No. 51425. The wave came in 165 seconds, that is, at a speed of 4.2 km/s. During this time, the tsunami wave travels only 33 km (velocity 200 m/s). It is easy to understand that the recorded anomaly is the vibrations of the seabed during the passage of the Rayleigh seismic wave. There is no need to pay attention to this anomaly. With the coordinates of this earthquake at DART station No. 51425, you need to start evaluating the data no earlier than 45 minutes later.

It's elementary simple, but DART doesn't understand us?

What is the right way to scale and use earthquake acceleration records (in form of spectral acceleration in first mode period) in time history analysis for 3D models? Is it ok to use max scale factors in two directions or should use the SRSS method?

Dear seismologists and residents of Turkey.

I suppose you want to know in advance (a few hours in advance): when you need to go to a safe place so as not to get hurt in case of an earthquake.

Only my method gives a sufficient lead, and only it has successfully passed the test.

If you need help let me know. We cannot stop the earthquake, but we can use the equipment and knowledge so that people do not die.

Write if you have questions or suggestions.

Sincerely.

Alexander Yagodin.

You can see how the anomaly was registered on my equipment in Haifa with a lead of 7 - 10 hours before the start of the aftershocks in Turkey.

I am searching time history data for turkey earthquake 2023. If anyone have any reference, kindly share.

Не так давно умерли Председатель Российского экспертного совета:

проф. А.В. Николаев и проф.Е.А. Рогожин, бывший и Председателем Экспертного совета России и Зам. директором РАН и председателем комиссий конференций...

В КНИГЕ ПАМЯТИ те, кто с ними работал пишут об уважении к ним, о том, что они были лидерами, экспертами. Честными, строгими.

Так почему сразу после их смерти их работу сваливают "в грязь", пытаются заткнуть автора?

Все знают, что научное заключение Генезиса землетрясений, данное РЭС положительное. Нет ни одной проработки этапов и действующих сил, чтоб все было логично и подтверждалось и теорией (скорость волны Козырева-Ягодина рассчитывается теоретически из движений Земли, Луны, Солнца) и скорость волны дает время прохода волны от станции до места, где произойдет землетрясение.

РУБЕН ЭДУАРДОВИЧ ТАТЕВОСЯН - Заместитель директора ИФЗ РАН непрерывно в своих выступлениях на публику повторяет, что "не существует точного классического краткосрочного прогноза землетрясений". Вы читали протокол РЭС по экспертизе работы Александра Ягодина (Председатель проф. А.В. Николаев).

Вы читали заключение по результатам испытаний !!!! Вы понимаете, что такое испытания и что означает заключение РЭС? Или Вы со смертью последних честных ученых уничтожили и то, что было "сделано до вас"?

ВАМ САМИМ НЕ СТЫДНО ЗА ИНСТИТУТ, ЗА СТРАНУ?

Вы заявляете ложь россиянам. Вы готовы убить людей в землетрясении, но скрыть то, что сделал А.Ягодин, поддержал Страшимир Мавродиев, проверили и подтвердили Николаев и Рогожин.

Вы эту ложь пишете и Президенту России, пользуясь тем, что Генеральный прокурор занят другими проблемами?

Интересно, все так лгут в РАН? Ни один человек не заявил правду, которую приняли на заседании РЭС 2015 года?

Not so long ago, the Chairman of the Russian Expert Council died:

prof. A.V. Nikolaev and prof.E.A. Rogozhin, former Chairman of the Expert Council of Russia and Deputy. director of the Russian Academy of Sciences and chairman of the conference committees ...

In the BOOK OF MEMORY, those who worked with them write about respect for them, that they were leaders, experts. Honest, strict.

So why, immediately after their death, their work is dumped "in the mud", trying to shut up the author?

Everyone knows that the scientific conclusion of the Genesis of earthquakes given by the RES is positive. There is not a single study of the stages and acting forces, so that everything is logical and confirmed by theory (the speed of the Kozyrev-Yagodin wave is calculated theoretically from the movements of the Earth, Moon, Sun) and the wave speed gives the time it takes the wave to travel from the station to the place where an earthquake occurs.

RUBEN EDUARDOVICH TATEVOSYAN - The Deputy Director of IPE RAS constantly repeats in his speeches to the public that "there is no accurate classical short-term earthquake forecast". You have read the protocol of the RES on the examination of the work of Alexander Yagodin (Chairman Prof. A.V. Nikolaev).

Have you read the conclusion of the test results !!!! Do you understand what tests are and what the conclusion of the RES means? Or, with the death of the last honest scientists, did you destroy what was "done before you"?

ARE YOU NOT SHAMED FOR THE INSTITUTE, FOR THE COUNTRY?

You are telling lies to the Russians. You are ready to kill people in an earthquake, but to hide what A. Yagodin did, supported by Strashimir Mavrodiyev, checked and confirmed by Nikolaev and Rogozhin.

Are you writing these lies to the President of Russia, taking advantage of the fact that the Prosecutor General is busy with other problems?

I wonder if everyone lies like that in the RAS? Not a single person stated the truth that was accepted at the REC meeting in 2015?

In my monograph "Interaction in the lithosphere-hydrosphere system" a review of scientific articles on the topic of using the energy of earthquake preparation for the formation of cyclones was reviewed. This topic was studied in most detail in my article "Influence of the gas component of the fluid regime of the lithosphere in the water area on atmospheric processes". The article shows that the hydrogen and methane released from the lithosphere before an earthquake and the oxidation energy are sufficient to form a local cyclone.

I have proved that changes in the gravitational field are also able to form a local cyclone. Slide from the discussion "Is it possible to see how rapidly the Earth's gravitational field is changing by looking at how clouds move (with their help and without GRACE)?" attached.

In the discussion "The earthquake in Turkey is a consequence of planetary scale geodeformations. Is the concept of stress accumulation before an earthquake wrong?" I have shown the coincidence of the pleistoseist zone of the Turkish earthquake with the atmospheric pressure anomaly. Such an anomaly arises with an increase in air temperature and with a local decrease in gravity. Attached are the maps from the discussion.

Let's discuss some synoptic maps over the epicenter of the Turkish earthquake.

In my opinion, the rate of atmospheric pressure change over the epicenter is extremely (anomalously) high. 02/02/023 - 1005 hPa, 02/03/23 - 1025 hPa, 02/06/23 - 999 hPa. This is not typical for the physics of the atmosphere.

I ask you to take part in the discussion of weather forecasters.

The question is what are the final goals of doing spectral analysis and what can we infer from that?

Is it from the fault that the earthquake arises or is it from the earthquake that the fault arises?

Dear all,

Turkey has been hit by several major earthquakes. Thousands of people died, millions lost their dearest and their homes. Turkey is trying to recover from both the figurative and real ruins. What would you suggest to do, both to academics and students affected by these earthquakes, to utilize academic studies to recover from these disasters? Thank you very much in advance.

Best wishes

The sorting out of the devastating earthquake has catastrophic economic, social and political effects on the Syrian economy and society, which is already suffering from a devastating war for more than 12 years. All of this creates new economic and social behaviors and practices, represented in dependence on aid, theft of aid, trading in aid, chronic unemployment, and runaway inflation. All of the above will produce a new Syrian political economy, I think. The question is, can this case not be called the political economy of the earthquake?

I am new to this research field. can anyone please tell me what is the most recent research which is currently emerging in this field?

Deformation waves not associated with earthquakes continuously pass over the surface of the Earth. These are waves with periods of 12, 24 hours and 14 days. Long waves are imperceptible to people, although they have an amplitude 10 times greater than seismic waves. In areas with a thin earth's crust, they usually do not provoke earthquakes (I do not consider mantle earthquakes). If the earth's crust is not subject to geodeformations, then they destroy it. After an earthquake, waves of geodeformation can provoke the collapse of buildings (before the earthquake, these territories were not deformed).

Video from INTERNET

Let's start the discussion.

I will quote information from my other discussion.

The earthquake in Turkey occurred on the date of the tide syzygy in the solid body of the Earth on February 6, 2023. On the dates of syzygy, the amplitude of geodeformations increases by no less than 20%. The first destructive earthquake occurred at 01:17 (M=7.8), the second at 10:24 (M=6.7). At this time, at the earthquake epicenter, the amplitude of the diurnal and semidiurnal tides in the solid body of the Earth reached positive extremes. In addition, due to the 14-day zonal tide in the solid body of the Earth, the conditions of stretching and compression of the Earth's crust were formed on the surface of the planet. The zonal tide in the solid body of the Earth is associated with the extrema of the angular velocity of the Earth's rotation. The data is available only for February 3. Attached the chart https://hpiers.obspm.fr/ . Stretch conditions on February 3 and February 10, 2023. On February 3, in accordance, rapid changes in the Earth's gravitational field on a planetary scale were recorded. Changes in the gravitational field recorded by our method, see satellite images https://meteologix.com/. Between the expansion phases, the compression phase is fixed. The compression occurred on February 6, 2023 and triggered an earthquake https://zn.ua/img/forall/u/14/8/photo_2023-02-06_15.16_.16_.jpeg . These are the facts of the formation of compression deformations on March 6. The scale is planetary.

Planetary-scale deformations (amplitude 30 cm) were blocked on February 6 in the epicentral zone of the future earthquake. The blocking of tidal waves in the solid body of the Earth is associated with the release of heat. In the atmosphere, the release of heat leads to a decrease in atmospheric pressure. Warm air weighs less. Look at the color map of atmospheric pressure and low pressure above the epicenter at the moment of maximum compression (map from Twitter https://twitter.com/BookofCrusty/status/1622643773900464128?t=Yy-KLEZn-FDuHvyIHh1y5w&s=09 ). The relapse occurred on February 20, 2023 after 14 days during the next cycle of the positive extremum of the angular velocity of the Earth's rotation associated with the repetition of the phase of the zonal tide in the solid body of the Earth.

A 10 X 10 three-story precast building with a floor area of 100 m2 with 30 cm thick concrete walls in a large earthquake with an acceleration of 1.5g has some overturning moment tendency.

Wanted 1. how much does the precast weigh

2.the inertia and shear base created at the 1.5g acceleration

3. plus the magnitude of the overturning moment of the entire building.

The building weighs 340 tons

Payload is 80kg/m2 = 24 tons

The floors another 24 tons

The building finally weighs 340+24+24= 388 tons without the base.

Inertia and base intercept = mass X acceleration = 388 ton X 1.5g = 582 tons

Overturning moment = height X inertia = the first floor is 3 m high the second 6 and the third 9 total 3+6+9 = 18m

Each of the three floors has an inertia of 582/3 = 194 tons

18mX194ton = 3492 ton overturning moment

But the precast as a rigid structure has a double lever arm, that of the height and that of the width.

So we divide the torque of 3492 tons by the width of the building which is 10 meters 3492/10 = 349 tons.

Every single anchor I have can withstand 100 tons of torque at two meters depth.

If we place 8 anchors around the perimeter, we will not have any loss of support from the ground due to the total withdrawal of the area of the base of the building, so no damage in the earthquake of 1.5g acceleration.

A 300 sq.m pre-fab house costs 310,000 euros finished today + 30,000 the eight anchors = 340,000 euros and you have the most earthquake-proof house in the world.

A conventional house today costs 2,000 euros per sq.m when finished, 300 sq.m costs 600,000 euros.

Choose.

My proposal for anti-seismic constructions is to prestress the sides of the reinforced concrete walls as well as to compact them with the foundation soil at the same time.

Prestressing + compaction on the sides of the walls Prestressing (generally compression) on the sidewalls has very positive effects, as it improves the oblique tensile trajectories. On the other hand you also have the other good thing... the non-shear failure of the cover concrete due to the high tensile strength of the steel, the reduced cracking and the increase in the elastic and dynamic displacement area due to compression, which increases the effective cross-section and stiffness of the structure, and most importantly increases the response of the cross-section to the intersecting base. If prestressing is combined with compaction in the soil then we divert the seismic loads into the soil, prevent the moments at the nodes, control the eigenperiod and ensure soil samples and a strong foundation.

Dear Respected Patron!

Now a days, its a burning question of the creations that "How to predetermine the Earthquake Signal?" So that, the early precaution may take measure to mitigate huge demolition and vulnerable lose of life.

It is not easy to forecast or predict an earthquake and till now there has been no successful prediction in history except one from a Chinese researcher in the mid-70s. But for the last few weeks, people have been expecting that planetary alignments are indicators of seismic events. So being an earthquake researcher I think it is quite difficult to highlight the exact area of the upcoming seismic events with the help of this technique. I need opinions from the scientific community on this topic.

Earthquakes are now causing fear and unstability in most iraqi and jordanion citizens who live in big building ,How can we secure building and check the standards of constructions?

Psychological impact of earthquake-related stress can sometimes be detrimental. Suicidal tendency, depression, anxiety and post-traumatic stress (PTSD) are some of the effects resulting from earthquake-related stress. How can governments and individuals help deal with earthquake related stress?

The recent earthquake in Turkey and neighboring countries.

I am looking for information on the latest earthquake in Turkey. Can anyone help me find accurate and up-to-date records or data for the event? I have searched the PEER website but I couldn't find any appropriate information. Any help or guidance would be greatly appreciated.

Can we propose newer seismic provisions for designing a building along a faultline of tectonic plates? Is it possible to safeguard the occupants of such earthquake occured recently in Turkey of magnitude 7.8 richter?

EEWS - a method of scammers to spend the budget without benefiting people?

EEWS and its "modifications" start from the moment that "there was an earthquake". (Method "p" - "S" is its analog, only other waves of ALREADY OCCURRED EARTHQUAKES are taken).

Several times I exhibited these methods that do not warn about the time, place, or strength of a future earthquake, and I asked scientists to show all the good and useful things that are in these methods.

No expert has claimed the beneficial properties of these methods.

Maybe then it is necessary to declare that only scammers use this method.

After all, what is spent on these senseless methods could be used for the benefit of people. Approximately the same was said at a meeting of the Commission of the Israeli Knesset in 2005.

Appeal to geophysicists and leadership of Turkey.

Greetings to you, colleagues. It's a tough time, I sympathize with you.

Moreover, I saw the anomalies of these two earthquakes ten hours before the start of the shocks.

For an accurate forecast, you need to have a network of five stations or more.

If you and your government want to create a working group that will supply equipment to seismic stations (for about 10 stations), then I am ready to give you advice on the interpretation of the Kozyrev-Yagodin wave, forecasting with high accuracy. I was offered this in a laboratory in Russia, but my children are in Israel and Turkey and I must, first of all, protect their lives.

On 6 February 2023, an earthquake of Magnitude 7.8 struck southern and central Turkey and western Syria. Two major aftershocks of 6.7 and 7.5 Magnitude soon followed. Thousands of people have lost their lives and the death toll seems to be increasing rapidly. Although the earthquake occurred in a highly seismically vulnerable region, the footages from the disaster-stricken area show a high number of building collapses.

What could be the reason for such building collapses (based on preliminary information)?

Can it be attributed to flaws in building design? or problems in design implementation? or lack of routine maintenance? or a higher degree of ground acceleration than anticipated? or any other reasons?

Some possible general explanations can be found at:

Hello good time To design a seismic isolator for bridges according to the Ashto code, we design a seismic isolator for a design earthquake (1000-year return period) and there are examples of this in the Ashto guide. If the goal of designing a seismic isolator is for MCE earthquake, what should we do? Unfortunately, I still haven't found the solution and method.

We all the time talking about the negative effects of EQs on the natural and artificial environments, is there any importance together with its destructions?

I am looking for recorded earthquake rotational time history (ground motion) data; both torsional and rocking. Is there any database to procure these data ?

I have some .SAC data showing the earthquake wave form but in their header magnitudes are not mentioned. The question is that how can I determine the magnitudes from .SAC files?

please suggest me a software used for the orthogonal regression.

Major earthquake events can cause ground deformation which can be detectable by GNSS. After a large event, GNSS data can even be used to improve moment magnitude estimations.

For smaller magnitude events, I was wondering what would be the threshold for magnitude/distance from the earthquake source that we can detect the earthquake's coseismic (+postseismic signal) signature on the GNSS time series.

On Nevada Geodetic Laboratory website (http://geodesy.unr.edu/NGLStationPages/stations/LEMN.sta), I saw this formula: "10^(M/2 - 0.79)", we input magnitude (M) to obtain distance value (km). If the distance between the GNSS station and the earthquake epicenter is less than the value we obtained from the formula, it is possible to see a step record on the GNSS time series.

I would really appreciate it if someone could recommend some papers related to this topic.

How to cut the real accelerogram earthquake record at some time interval to ensure that the maximum effect of the complete earthquake record is achieved by cutting the record up to some extent?

Is there any criteria or guideline to cut the record based on... i.e. Ground motion intensity, Energy etc.. Or any other ?

My FE model is very large and need to perform the seismic analysis using cutted earthquake record.

I greet you, dear colleagues.

I live in Haifa and the officials did not allow me to participate in the short-term earthquake forecast project competition, despite the fact that I was supported by professors from one of the universities in Israel. The chairman of the commission and his consultant were deceived into denying the competition and gave 33 million shekels to "systems that report that an earthquake has already begun."

You can get acquainted with my methodology and the discovery of the genesis of earthquakes. My work received positive opinions from official scientific experts and was successfully tested on real earthquake forecasts in real conditions under the control of individual experts and an official expert: the Russian Expert Council.

Initially, the Chairman of the REC prof. A.V. Nikolaev, then the Chairman of the RES; the Deputy Director of the IPE RAS for Science prof. E.A. Rogojin, confirmed with positive conclusions the successful tests of real forecasting by the monitoring method of the Kozyrev-Yagodin wave (KaY-wave).

In the conclusion of the examination, it is stated that the tested methodology and system is recommended as the basis for building an international network of short-term forecasts: place, time, strength of a future earthquake with a certainty of about 100% tens of hours before the start of the tremors and indicating when the tremors will end. The forecast resolution between adjacent shocks is about an hour.

I am already 75+ and therefore I want to create a Center from which to build a network and to whom I will transfer the main part of the patent and my knowledge accumulated over 20 years of work.

This may be an association of state institutions or institutions, as well as the inclusion of private investors and specialists. It can be specialists from any state of any religion, any government system.

Sincerely.

Alexander Yagodin.

I enclose some of the expertises that I sended the Chief Scientist of the Israeli Ministry of Defense and after that I was invited to the 2017 Knesset Commission meeting.

I declare that the methodology for short-term forecasting has been created, and successfully passed tests and official examinations. This technique and system will reliably save people's lives in the event of an earthquake. The method was patented and published in 2008. The scientific article of the foundation was published at the conference in 2011 and presented to all experts in Russia and international experts in 2015. You can see the minutes of the meeting.

Many seismologists of the world pretend that this does not exist and sell the people ersatz, which will not only continue to kill people with an earthquake but also kill children with panic in schools.

I challenge such "scientists" to debate. I declare that they use their position as leaders to get millions from the budget without real competition. For example, in Israel, received 33 million shekels in this way, but their method and system (EEWS) will not save people's lives. The "creators" of the method at the meeting of the Knesset Commission did not want to declare that they are responsible for the results of their "labor".

What to believe? Implement something new?

Or implement what scammers get money for?

Geophysicists and the Government of Italy, I propose to contact me urgently.

You all know that a geophysicist has no right to make a forecast for the public.

I now have only one L-wave sensor and it is installed in the house, there is no protection against technical noise, therefore I have no right to give any forecasts and I cannot give 100% certainty.

However, if you are expecting a high-loss earthquake, please contact me immediately. I am ready to receive your representatives in Haifa, conclude an agreement and show how the sensor is made, set up communication with seismic stations in Italy, and possibly in the Vrancea zone. This will allow you to get accurate forecasting ten hours before the start of an earthquake in your area. We see that after the earthquake, surface waves continue to fluctuate and we see a serious earthquake on the opposite side of the planet (Fiji). This is not a harbinger, but it indicates an increase in the planet's seismic activity.

Sincerely. Alexandr Yagodin.

WO2008053463 - SYSTEM OF THE PREDICTION OF THE EARTHQUAKE

We found a lot of documents in Tappe Sialk Kashan that occurred an earthquake which after that architecture developed and became better than before

This is a question about earthquake amplitude attenuation.

With your experience of observing earthquake waveforms or simulating ones, I hope you will give us some insight on that matter.

I'm trying to simulate the PGD/PGA attenuation along a given azimuth of an earthquake magnitude 5.5, reverse fault (S:215 D:50 R:84), with point source simulation.

The process is to simulate synthetic seismograms at each stations separated with equidistance (~5km). A 1-D tabular velocity model is used.

We consider only the horizontal components (radial and transversal); and the PGD/PGA is the maximum between them.

The results I'm getting are strange for me.

The figure attached shows the PGA amplitude of 40 stations in two directions: azimuth 45° and azimuth 125°.

I was expecting a constant regular attenuation from the nearest station to the farthest one. Instead, I got two sudden decrease followed by an increase in the amplitude (around 56km and 130km for the example shown in the figure attached).

I did run several tests and this anomaly (if it is), doesn't seem to be affected by the event depth or with seismic nuting.

I would like to know if in such condition (ideal conditions without any amplification factors at the surface) we expect an amplification in amplitude (due to ordinary wave behavior such us multiple) ?

Or is it expected, especially with reverse faults? Since the chosen azimuths (45° and 125°) are ~ parallel and perpendicular to the strike?

Or is there any other explanation or error that I'm missing.

Thank you in advance for your help

I am performing the earthquake analysis on bridge structure in ABAQUS CAE under Dynamic Implicit step. I am getting the error as shown in the picture attached.

All elements are C3D8R.

How to resolve this error?

How to sell a part of a patent and build a global network of short-term forecasts if the discovery and technique were created by an individual author?

For example:

Appeal to the seismologists of the Arab countries.  With the aim of establishing a Near East short-range earthquake forecast network, I am offering to the Arab countries (via Jordan or via the UAE) part of the short-range earthquake forecast patent and my assistance in processing the materials for the forecast. The system and method have successfully passed the tests of earthquake prediction in real conditions with high accuracy and reliability - 95-100%.

I am interested in the impact of the 2015 earthquakes on the springs. There are many anecdotal reports of springs drying or shifting, but is there any hard evidence of the impact?

As a result of bottom uplift during an earthquake, an ordinary trochoidal surface (transverse) wave occurs. There are no other opinions. The first slide shows the generally accepted wave generation mechanism. The second slide shows a diagram of the motion of particles in a surface wave. Everyone thinks so. In 2006 in Vienna, at the Intergovernmental Oceanographic Commission's Tsunami (EGU2006), I asked everyone why a tsunami begins with an outflow of water from the coast. My question was of no interest. The third slide shows that the water will first move away from the shore. The fourth slide shows that in the open ocean there is a hole first and then a mountain. Maybe this is not a trochoidal wave, but a Rayleigh wave? The scheme of the Rayleigh wave is shown on the fifth slide. If this is so, then the tsunami formation mechanism (first slide) is wrong?

Seismic moment gives us the release of the energy during earthquake. If this could relate to the PGA expected at site, we could estimate the PGA from moment magnitude itself. Probabilistic seismic hazard analysis is an elaborate procedure to get this but a direct relation can save a lot of time and calculations.

I am doing my MTech thesis on topic “ANALYSIS OF SEISMIC SEPARATION GAP BETWEEN TWO ADJACENT REINFORCED CONCRETE BUILDING” and i am planning to use FVD250 between two adjacent buildings, so what will be the cost of one single viscous damper and is it good idea to use FVD between building?

Geothermal energy is a renewable energy generated from earth's heat which can be harvested for human use. However, my first question is about is there any solution for absorbing and utilizing the earthquake energy and if possible can that be done by using geothermal energy. I know that earthquake energy is quite immense and difficult to do this practical which requires high technology and more expensive too but is there any possibility even though to resolve this issue?. Please, kindly respond.
