Prime Minister Narendra Modi spoke to Sonowal twice. “I pray for the well-being of the people of Assam,” Modi tweeted.
Union Home Minister Amit Shah, Union Finance Minister Nirmala Sitharaman and DONER Minister Jitendra Singh also called Sonowal and took stock of the damage. All necessary help and support to the state government has been assured.
Sonowal, who visited Dhekiajuli on Wednesday evening, said the district administrations were directed to carry out a field survey of the damage, submit reports for a detailed review and extend necessary help and support to those affected.
The primary tremor on Wednesday morning has its epicentre at 26.690 N and 92.360 E and a focal depth of 17 km, according to a report by the National Centre for Seismology.
“The preliminary analysis shows that the events are located near to Kopili Fault closer to Himalayan Frontal Thrust (HFT). The area is seismically very active falling in the highest Seismic Hazard zone V associated with collisional tectonics where Indian plate subducts beneath the Eurasian Plate,” the report said.
The report said the “historical and instrumentally recorded earthquake data” showed that the region has been affected by “moderate to large earthquakes”, the most prominent among them on July 29, 1960 of magnitude 6.
