United Nations SDGs-11 focuses on safe, resilient, sustainable cities and human settlement. Importance given to implement the Disaster Risk Reduction strategy where the number of death and economic loss to be reduced. Seismic disaster risk reduction is one of the major task in SDGs., The occurrence of earthquake in the Himalayan region is continuou...

A significant amount of energy is released from sub-surface during an earthquake which is caused by seismotectonic activity. The occurrences of earthquake and its distribution pattern are necessary to correlate with concentrated and deviated energy in the sub-surface for better understanding the seismotectonic activity. Hence, the main aim of the p...

The different morphotectonic parameters have been analyzed for estimating tectono-geomorphic anomaly index (TGAI). The analysis of river long cross-profile and hypsometric curve has been integrated with the TGAI and epicenter distribution for monitoring tectono-geomorphic anomaly in Lower Tista sub-basin, India. Higher value of TGAI is observed in...

Landslide is a widespread hazard in the Himalayan region that occurs during the monsoon season due to heavy rainfall. The seismicity in the active thrust region is also induced landslides which brings instant disaster by the destruction of infrastructures and communication system. The advancement of remote sensing techniques help to identify the la...

Landslide is a devastating natural hazard, which causes significant losses of human lives and properties. The landslide occurrences are the perennial problem in Himalayan region where it is controlled by several parameters such as physical (relief, slope, geomorphology and soil), lithology, tectonic and seismological activity. The main aim of the p...

The Zagros fold-thrust belt is seismically active which produces large earthquakes in recent times. In the present study, the Shivah Lalayi basin has been selected which is the part of the Greater Zab river basin and covers the segment of the Zagros fold-thrust belt in the northern part of Iraq. Researchers have extensively worked between 2000 and...

The natural system of the drainage basin is interrupted by sub-surface faults and active tectonic processes. The anomalous nature of the drainage network and its basic morphological characteristics produce significant geomorphometric anomalies of the drainage basins which are an indicator of seismotectonic activity. In recent years, the increasing...

p>The prediction of a natural calamity such as earthquakes has been an area of interest for a long time but accurate results in earthquake forecasting have evaded scientists, even leading some to deem it intrinsically impossible to forecast them accurately. In this paper an attempt to forecast earthquakes and trends using a data of a series of past...

The anomalous nature of basin morphological characteristics produces significant geomorphic anomaly which is the indicator of seismotectonic activity. In recent years, the increasing frequency of earthquakes and subsequent damages to infrastructures in Indian sub-continent reveal to study the seimotectonic earthquake. Hence, the present research fo...

Earthquake is a geological natural hazard which is shaking of earth’s surface due to seismic activity. The Himalayan region and quaternary geological surface of Indian sub-continent had experienced several earthquakes in the recent geological period due to reactivation of existing faults. Surface drainage system and its morphometric characteristics...

An earthquake is a natural phenomenon which is very frequent in Himalayan region in India. In southern peninsula India, the spatial occurrence of earthquake is irregular, whereas the northeastern, the north and the northwestern Himalayan parts of India are subjected to regular occurrences of earthquakes as they mark the boundary of the Eurasian and...

An earthquake is a natural hazard which is induced due to the displacement of land mass along the active fault and release sub-surface energy. The concentration of the energy in the sub -surface is the major driving force for the landmass movement along the fault. The literature study depicts that there is some research gap in seismic hazard study...

The phenomenon of earthquake is the major seismic event occurring in the subsurface rupture zone. In the recent years, specifically active tectonic zones are more important due to its frequent occurrences of earthquakes. The main aim of the present research is to determine the threshold energy by studying the relationship between various geomechani...

Wetland is a valuable and most important natural resource in the environment. The present research aimed to study the wetland spatial dynamics by analysing the multidated satellite images and to develop a wetland mitigation plan through integrated geoinformatics techniques. The four stages of methodology include data acquisition, thematic database...

Lake is the important part of the wetland and also the main source for agricultural irrigation, domestic water supply and industrial requirement. It maintains the aquatic ecosystem and also considered as the major place for biodiversity conservation. The lake area is getting reduced due to increase in siltation and eutrophication processes in the a...

The major causes for lake morphological changes are the increase in siltation due to soil erosion in the catchment area followed by eutrophication processes.The dynamic changes in the lakes create an adverse effect on the lake environment and the aquatic ecosystem. The main objective of the present research is to study the lake morphological change...
