Nepal Hit Again: 7.3 Earthquake Aftershock
Nepal 7.3 earthquake is considered an aftershock.
Emergency officials in Nepal say at least 80 people have died in Today’s earthquake, which hit as the country is still in search and rescue mode from a prior quake that killed more than 8,000.
The 7.3 Nepal earthquake (SE of Zham, China) occurred as the result of thrust faulting on or near the decollément associated with the Main Himalayan Thrust, which defines the interface between the underthrusting India plate and the overriding Eurasia plate to the north. At the location of this earthquake, approximately 80 km to the east-northeast of the Nepalese capital of Kathmandu, the India plate is converging with Eurasia at a rate of 45 mm/yr towards the north-northeast – a fraction of which (~18 mm/yr) is driving the uplift of the Himalayan mountain range. The May 12, 2015 event is the largest aftershock to date of the M 7.8 April 25, 2015 Nepal earthquake – known as the Gorkha earthquake – which was located 150 km to the west, and which ruptured much of the decollément between these two earthquakes.
