Within an hour, more than 70 felt reports related to this earthquake were received from Delhi, Uttarakhand, Uttar Pradesh, Bihar, Himachal Pradesh, Rajasthan and Punjab through the NCS website and mobile app. These reports indicated intensities ranging from I to III on the Modified Mercalli Intensity (MMI) Scale
New Delhi:
Four earthquakes, the strongest being of magnitude 6.2, jolted Nepal in quick succession on Tuesday with tremors reverberating through parts of north India, including Delhi-NCR, the National Centre for Seismology (NCS) said.
An NCS official said the first quake of magnitude 4.6 struck west Nepal at a depth of 10 km at 2:25 pm, followed by the 6.2 magnitude jolt at 2:51 pm.
Two more quakes (magnitude 3.6 and 3.1) hit the same region at a depth of 15 km and 10 km at 3:06 pm and 3:19 pm, respectively.
The epicentre of the strongest quake was located in Dipayal district in west Nepal, 206 km southeast of the pilgrimage town of Joshimath in Uttarakhand and 284 km north of Uttar Pradesh’s capital Lucknow.
“The events were recorded by more than 60 broadband seismic stations installed by the National Centre for Seismology. The analysis of seismic data shows that the events occurred on the North Almora Thrust (NAT), which provides a very suitable location for triggering the mainshock due to appreciable structural heterogeneity in and around the mainshock. The preliminary fault plane solution derived from moment tensor inversion suggests a thrust fault,” the NCS said in a report.
Within an hour, more than 70 felt reports related to this earthquake were received from Delhi, Uttarakhand, Uttar Pradesh, Bihar, Himachal Pradesh, Rajasthan and Punjab through the NCS website and mobile app. These reports indicated intensities ranging from I to III on the Modified Mercalli Intensity (MMI) Scale.
