Series of Earthquakes Jolt Nepal and Parts of North India - Strongest at Magnitude 6.2

On Tuesday, four successive earthquakes struck Nepal with tremors felt across north India including Delhi-NCR, as reported by the National Centre for Seismology (NCS). The strongest quake recorded had a magnitude of 6.2 and was located in west Nepal's Dipayal district.

On Tuesday, October 3rd, Nepal was hit by a series of four earthquakes in quick succession. The strongest of these had a magnitude of 6.2 and its effects were felt across parts of northern India, including the Delhi-NCR region. This information was confirmed by the National Centre for Seismology (NCS).

The Sequence of Events

An NCS official reported that the first earthquake struck west Nepal at 2:25 pm with a magnitude of 4.6 and a depth of 10 km. It was quickly followed by the most powerful quake at 2:51 pm which registered a magnitude of 6.2 on the Richter scale. Two more tremors were recorded in the same region with magnitudes measuring 3.6 and 3.1 respectively; these occurred at depths of about15 km and10 km at timings - approximately around 3:06 pm and again at roughly around about19 minutes past three.

Epicentre Location and Impact

The epicentre for the strongest quake was located in Dipayal district which is situated in west Nepal, approximately some206 kilometres southeast from Joshimath –a well-known pilgrimage town located within Uttarakhand state; it also lies roughly284 kilometres north from Lucknow, which is Uttar Pradesh’s capital city.

Data Collection & Analysis

These seismic events were captured by over sixty broadband seismic stations installed across various locations by the National Centre for Seismology (NCS). A detailed analysis conducted on this collected seismic data revealed that these series events took place along North Almora Thrust (NAT). This particular location offers an ideal setting to trigger mainshock due to its significant structural heterogeneity within as well as surrounding areas where mainshock occurs.

Fault Plane Solution

The preliminary fault plane solution derived from the moment tensor inversion suggests that these earthquakes were a result of a thrust fault, as stated in the report published by NCS.

Conclusion

This series of earthquakes in Nepal and its subsequent tremors felt across North India underscores the need for constant vigilance and preparedness against such natural disasters. The data collected by institutions like NCS not only helps to understand these seismic activities better but also aids in strategizing effective disaster management plans. It is crucial to continue investing in such research and infrastructure development which can potentially save many lives during such calamitous events.
