An earthquake measuring 7.1 on the Richter scale originating 83 km east of of Kathmandu and 30 km South-East of of Kodari in Nepal, was felt across north India and West Bengal a little after 12.30 this afternoon. In Kolkata, people rushed out of their offices in the central business district, causing traffic snarls.
According to the MHA two earthquakes struck India with epicentres in Nepal (7.1 on Richter scale) and Afghanistan (6.9 on Richter scale).
The National Geophysical Research Institute in Hyderabad, said this was the largest aftershock recorded since the earthquake of 7.8 magnitude that struck Nepal on April 26.
N Purnachandar Rao, an NGRI Siesmologist, said almost 100 aftershocks have been recorded since the Nepal quake last month, many of them with a magniture between 5-6 on the Richter scale.
He said the present earthquake can cause further damage to structures which have been weakened. Though large aftershocks are not unusual, a tremor of this magnitude could cause further damage.
According to agency reports, the powerful earthquake, epicentred in Nepal, shook West Bengal, Delhi and several parts of north India.
Immediately after the quake at around 12:35 pm, panic-stricken people were seen rushing out of buildings in Delhi.
Metro services were immediately put on restricted mode with speeds being slowed down.
Authorities said in many areas, high-rise buildings are being vacated.
