It also seems possible that specific types of failure are related to certain rock types and properties. Rebecca Bendick has studied the April 2015 quake as well as previous earthquakes in the area to find what the area's seismic future looks . . More on the Topic. This movement leads to collision of the Indian Plate with the Eurasian Plate, that causes frequent tremor and isostatic imbalances. This natural predis-position is exacerbated by anthropogenic processes, including land use changes, urbani-zation, and population growth within landslide affected areas (Petley, 2010).

The Indian Himalayan region is no exception to landslide incidences affecting key economic sectors such as transportation and agriculture and often leading to loss of lives. The elevation ranges from 4000 to 8848.86 masl. It is located in Zone V in the earthquake hazard zoning map of India. . Whereas the Western Ghats region is tectonically more stable and has less frequency of tremors and landslides due to it. Towards each other at some places and away from each other a. According to its study, there will be a 30-70 percent rise in the frequency of landslides in the border regions of China and Nepal that would pose threats to the region's infrastructure and communities living downstream.
