COASTAL SEISMICITY Low to Moderate Seismicity from coastal regions- Case Studies from East Coast of India
Peninsular India is often faced with two major natural hazards namely the cyclone and storm surges in the coastal areas and the intraplate seismicity in the main land and coastal areas. We have now fairly a well established weather forecasting mechanism to cope up with high cyclone and storm surges. The other natural hazards is the continental earthquakes like the Latur (1993), Jabalpur (1997), Bhuj (2001) which caused huge devastation, including heavy human losses. These earthquakes are the result of the reactivation of subsurface weak zones beneath the continental shield. The reactivation is due to compressional stress accumulated on the Indian Plate as it moves northward in the overall plate Kinematics of this part of the earth.
