Nepal earthquakes impact Gangetic plains as region's soft soil amplifies seismic energy, say experts
Gangetic plains because the soft soil of the region amplifies seismic energy originating from the Himalayan belt, seismologists said. On Friday night, a strong earthquake of magnitude 6.4 jolted Nepal sending waves of tremors across north India, including in Delhi-NCR.
The National Centre for Seismology (NCS) had said the epicentre of the earthquake, which struck around 11.30 pm, was in Nepal, about 227 km north of Ayodhya in Uttar Pradesh and 331 km west northwest of Kathmandu.
It has claimed at least 143 lives and injured more than 150 in the Himalayan nation, and is the worst since 2015.
While seismologists warned that consecutive earthquakes are foretelling bigger seismic shocks in the western Nepal Himalayan region, an examination of the preliminary reports published by the NCS paint a geographical picture of the parts of India that experience these Nepal quakes and hence, are susceptible to them.
The centre issues such reports hours following an earthquake, detailing information about its epicentre and its depth, a preliminary analysis of the cause of the shocks, and the regions in India that felt the earthquake.
Its preliminary report on the November 3 seismic event said that it was widely felt in Delhi-NCR and neighbouring states. More than 90 «felt reports» were filed in from Delhi, Uttarakhand, Uttar Pradesh, Bihar and Haryana through the NCS' website and mobile app, the report said.
