Community Event Response to the 25 April 2015 Mw 7.8 Gorkha, Nepal Earthquake

Posted 25 April 2015

Last updated 15 May 2015

Event Overview

From the USGS Event Page, 25 April 2015: The April 25, 2015 M 7.8 Nepal earthquake occurred as the result of thrust faulting on or near the main frontal thrust between the subducting India plate and the overriding Eurasia plate to the north. At the location of this earthquake, approximately 80 km to the northwest of the Nepalese capital of Kathmandu, the India plate is converging with Eurasia at a rate of 45 mm/yr towards the north-northeast, driving the uplift of the Himalayan mountain range. The preliminary location, size and focal mechanism of the April 25 earthquake are consistent with its occurrence on the main subduction thrust interface between the India and Eurasia plates. For more information, see the USGS Earthquake Hazards Program event summary.
