Article
Full-text available
The creation of earthquake hazard maps requires various datasets with selected attenuation relations. Based on the selected attenuation relation, the calculation time varies from half an hour to a couple of days. The length of time needed to create an earthquake hazard map also depends on the resolution of the resulting map. The time gets longer as...

Definition of an earthquake includes parameters with respect to region of interest. Each of those parameters has different weights on the earthquake ground motion and effect. This study examines the weight of common parameters that have an influence on the effects of earthquakes. The Analytic Hierarchy Process (AHP) is used for factor weighting of...
Article
The two important earthquakes that occurred in Turkey in 1999 have increased concerns on what would happen if a major earthquake affects Istanbul again. Alarming estimates reveal that Istanbul will probably be exposed to a devastating earthquake, with a magnitude between 6.5 and 7.7, in the next 25–30 years. The necessity of comprehensive plans for...
Article
The development of a general purpose disaster impact assessment software package is a daunting task, complicated by a number of technical, political, and administrative challenges. For example, geospatial information management should account for the administrative system of the country subject to the assessment, while the hazard, fragility, and in...
Article
A new generation of tools is needed to allow researchers and practicing engineers the ability to leverage investments in new methodologies and software infrastructure while enabling customization to local conditions. MAEviz represents such a next generation of seismic risk assessment software, based on the Mid-America Earthquake (MAE) Center resear...

Data availability to respond to a natural disaster is a tender spot to prevent secondary deaths. Authorities need a map showing spots with the annotations of the level and the size of the emergency to manage response teams. Whilst conventional spatial data acquisition techniques (such as; photogrammetry, remote sensing) seen somehow eligible to use...
Article
Over the past 20 years, the development of offshore wind farms has become increasingly important across the world. One of the most crucial reasons for that is offshore wind turbines have higher average speeds than those onshore, producing more electricity. In this study, a new hybrid approach integrating Interval Rough Numbers (IRNs) into Best Wors...
Thesis
Social Media is a new age of data sources that emerged in the last decade. Users who have diverse different motivations (such as; entertainment, communicating, or promoting) sign up the platforms worldwide. Currently, there is 3.5 billion active social media account worldwide. This growing number of account holders are accepted as human sensors tha...

Social media (SM) can be an invaluable resource in terms of understanding and managing the effects of catastrophic disasters. In order to use SM platforms for public participatory (PP) mapping of emergency management activities, a bias investigation should be undertaken with regard to the data related to the study area (urban, regional or national,...

Determination of the location of a research station in Antarctica is a very important issue, and necessary for countries to have sustainable Antarctic Scientific Program and expeditions. The suitable site selection is affected by long-term scientific work plan, its realization costs, and field experience on the continent. For this purpose, using a...
Conference Paper
The credibility of Social Media (SM) data, and generally speaking crowd-generated content, has been questioned by many. The credibility could be even more questionable if a part of information is inferred from such contents as the inference itself can add to the uncertainty, reliability, and credibility. This is the case for the absolute majority o...

Full-text available
Worldwide, earthquakes and related disasters have persistently had severe negative impacts on human livelihoods and have caused widespread socioeconomic and environmental damage. The severity of these disasters has prompted recognition of the need for comprehensive and effective disaster and emergency management (DEM) efforts, which are required to...

Article
For many years, researchers have been warning that Istanbul will encounter a devastating earthquake in the very near future, which is likely to cause extensive damage to buildings, bridges and roads. In order to be able to take substantial precautions and manage any disaster in the best way possible, analyses are required not only of the expected s...

Full-text available
Istanbul is located in one of the most active seismic zones in the world. Since Istanbul is the industrial, commercial, cultural and educational center of Turkey, it attracts ongoing migration from all over Turkey. However, those migrations caused unplanned construction and those unplanned constructions led to the formation of vulnerable and undocu...

Full-text available
Although the occurrence of earthquakes cannot be prevented, the vulnerabilities of them can be mitigated by decreasing the population, strengthening the vulnerable assets or both. The impact of the earthquake would be even higher if it is not managed properly. Istanbul has been affected by earthquakes throughout its history. The most recent damages...

Istanbul has been affected by earthquakes throughout its history. The most recent earthquake to shake Istanbul was on August 17 1999, along the North Anatolian Fault, 12 km southeast of the Izmit Province, with a magnitude of 7.4. Following the 1999 Izmit earthquake, the earthquake risk in Istanbul started to draw attention and many scientific stud...
