Major earthquakes that shook Northeast India in the past decade

SHILLONG: 

The 6.4 magnitude quake that shook Assam and parts of the northeast on the morning of April 28, Wednesday, is a reminder that almost the entire region of northeast India lies on the highest prone earthquake belt, seismic zone V. 

The quake, which occurred 80 km away from Guwahati near Dhekiajuli in the Sonitpur district of Assam at about 7:51 am, is a reminder that a fool-proof disaster management plan in the region is necessary to tackle such crises at any point.
 
Fault lines 

Multiple aftershocks struck Assam after the first quake. The National Centre for Seismology (NCS) has attributed the multiple quakes to the Kopili fault zone closer to Himalayan Frontal Thrust. This is a seismically active area falling in zone V.

A fault line is basically a fracture in the rocks of the Earth’s crust, which has been created due to a mass movement caused by the displacement of rocks.

According to DownToEarth, the Kopili fault zone has witnessed many seismic activities in the past, including the 1869 earthquake (7.8 magnitude) and the 1943 earthquake (7.3 magnitude). 

The Kopili fault zone is a 300 km long and 50 km wide lineament (linear feature) extending from the western part of Manipur up to the tri-junction of Bhutan, Arunachal Pradesh and Assam.
