The North Eastern Region of India is a mega-earthquake prone zone caused by active fault planes beneath formed by the convergence of three tectonic plates viz. India Plate, Eurasian Plate and Burma Plate. Historically the region has suffered from two great earthquakes (M &gt; 8.0) – 1897 Assam earthquake and 1950 Assam-Tibet earthquake – and about 20 large earthquakes (8.0 &gt; M &gt; 7.0) since 1897. The 1950 Assam-Tibet earthquake is still the largest earthquake in India.
