 Nepal's Tectonic Summary (USGS analysis)

The April 25, 2015 M 7.8 Nepal earthquake occurred as the result of thrust faulting on or near the main thrust interface 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 – a fraction of which (~18 mm/yr) is 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 decollément associated with the Main Himalayan Thrust, which defines the subduction thrust interface between the India and Eurasia plates.

While commonly plotted as points on maps, earthquakes of this size are more appropriately described as slip over a larger fault area. Events of the size of the April 25, 2015 earthquake are typically about 100x50 km in size (length x width); early modeling of this earthquake implies dimensions of ~120x80 km, directed from the hypocenter eastwards, and towards Kathmandu. As a result, substantial seismic energy was generated by faulting very close to the city.  

 

The boundary region of the India and Eurasia plates has a history of large and great earthquakes. Four events of M6 or larger have occurred within 250 km of the April 25, 2015 earthquake over the past century. One, a M 6.9 earthquake in August 1988, 240 km to the southeast of the April 25 event, caused close to 1500 fatalities. The largest, an M 8.0 event known as the 1934 Nepal-Bihar earthquake, ruptured a large section of the fault to the east of this 2015 event, in a similar location to the 1988 earthquake. It severely damaged Kathmandu, and is thought to have caused around 10,600 fatalities. Prior to the 20th century, a large earthquake in 1833 is thought to have ruptured a similar area as the 2015 event.
