Strong Earthquake Hits Nepal and India; 20 People Dead, Over 100 Injured

A strong earthquake measuring 6.9 moment magnitude (Mw) rocked north east of Nepal, India, and Bangladesh. The quake claimed at least 20 lives, 15 in India and 5 in Nepal, and injured over100 people.  Strong tremors were felt in Nepal on Sunday evening, at 6:25 pm. This is the strongest quake hit the country in 78 years. Accord U.S. Geological Survery (USGS) and National Seismological Center, Nepal, the epicenter was between Taplejung, eastern Nepal, and the Indian state of Sikkim (27.723°N, 88.064°E). The hypocenter (earthquake focus) was shallow (20 km) and located north east of Ghunsa village, Taplejung.

Among the five death reported in Nepal, three people died in Kathmandu after the compound wall of the British Embassy at Lainchaur collapsed in the aftermath of the quake, and two died in Dharan when the ceiling of their house fell down. Fifteen people died in north east areas of India, including two army personnel. Hundreds of people have been injured both in India and Nepal. Major damages have been reported from Gantok, Sikkim. The quake damaged buildings, affected transportation network, power supply, and mobile and telephone networks.

This is not a typical Himalayan earthquake! Be Careful...

According to technical details available in USGS website, this earthquake is not a typical Himilayan earthquake. The earthquake was generated by strike slip fault rather than a typical thrust interface plate boundary between upper Eurasian plate or the underlying India plate.In a Facebook group, Dr. Subesh Ghimire indicated that due to the different earthquake mechanism involved in this quake, the future prediction of earthquake based on seismic gap in Nepal could be still valid and pose a threat in near future.
