Why are there more earthquakes in the Himalayas and in the north-eastern region of India ?
The Indian plate is moving at a speed of one centimetre per year towards north and north eastern direction and it is obstructed by Eurasian Plate.
As a result of this, both the plates are said to be locked with each other resulting in accumulation of energy at different points of time. Excessive accumulation of energy results in building up of stress, which ultimately leads to the breaking up of the lock and the sudden release of energy causes earthquakes along the Himalayan arch.
