Mains articles have more focus on analysis and prelims articles have more focus on facts. However, this doesn’t mean that Mains articles don’t cover facts and PT articles can’t have analysis. You are suggested to read all of them for all stages of examination.

Deformation of the crust is also accommodated A fault is a fragmentation or zone of fractures along splay structures including the between two blocks of rock. Faults allow the ! Himalayan Frontal Thrust (HFT) blocks to move relative to each other in different ! Main Boundary Thrust (MBT) directions. ! Main Central Thrust (MCT) This movement of blocks of rock can be rapid, in the form of an earthquake or may occur slowly, Himalayan Thrust which is called as creep. Range of a fault can be few millimeters to Himalayan Frontal Thrust thousands of kilometers. Most faults produce ! The Himalayan Frontal Thrust (HFT), also known repeated displacements over geologic time. as the Main Frontal Thrust (MFT) is a geological During the earthquake disaster, the rock on one fault in the Himalayas that defi nes the boundary side of the fault suddenly falls over with respect between the Indian and Eurasian Plates.

Hence it is desirable to stress on the need of earthquake preparedness and enforcement of Due to high population density, urbanization, good construction practices. Seismological and deforestation and unprecedented growth of poor GPS networks in the Himalaya should be installed construction in the Himalayan foothills and Indo- other than the continuing efforts to understand Gangetic plains, scientists are of the view that the earthquake occurrence processes through, it is even the occurrence of a single major earthquake important that early earthquake warning systems will be disastrous for the region.
