Six killed, over 90 injured as quake rocks Northeast India


Nine aftershocks occurred till Monday noon in the wake of the 6.7 magnitude temblor that occurred in Manipur in the early hours.

The aftershocks including a 3.6 magnitude tremor were recorded by the CSIR-National Geophysical Research Institute’s broadband seismological network, which was installed in the North-east region.

“When earthquakes of this magnitude occur, they are followed by aftershocks which are expected to continue for a few days”, said D. Sri Nagesh, seismologist and head of the seismological observatory at NGRI here.

Terming the main event as a “strong earthquake”, he said that it occurred in a seismically active region where the Indian plate was subducting below the Burmese plate. It occurred at a depth of more than 25 km.

He said the region was located in intermediate-depth seismic zone where earthquakes occur up to a depth of 300 km, while shallow tremors occur up to a depth of 35 km.

He said that there were only three regions in the world where intermediate-depth earthquakes occur – Indo-Burmese plate region, Hindu Kush region and near Greece in the Aegean area. More info
