Lineament tectonics : Its relation to seismic activity in India

ABSTRACT

Structural changes in the earthsïs crust develop continuously due to a slow and gradual movement of an overstressed part of the earth. These changes normally termed as tectonic plates are formed due to their ultimate relationship to the development of the structure of the earth. Volcanic activity, ground subsidence and tectonic stresses all set up strong motions. Tectonic is responsible for almost all the worldïs earthquakes and geological faulting. Impacts of earthquakes on the buildings normally depend upon Magnitude, Duration, and Acceleration of the strong motion of the ground and vulnerability of buildings. The Indian subcontinental plate, after getting detached from its Gondwanic partners in the early Cretaceous, moved rapidly subducting underneath Asia and Burmese plates followed by a collision resulting in the episodic lift of the Himalayas.
