Catastrophic Earthquake in Nepal
A terrifying earthquake of magnitude 7.8 has hit Nepal on April 25, 2015, causing thousands of victims and devastating losses. We would like to express our condolences to all those who have lost close relatives and friends. We share the grief and convey our sympathy for all those who have lost their livelihood. We would like to let all Nepali people know, that we are with you and that you can count on our solidarity to overcome this extremely painful moment of despair. The earthquake occurred approximately 80 km to the northwest of the Nepalese capital of Kathmandu, as a result of thrust faulting process between the subducting India plate and the overriding Eurasia plate to the north. At the location of this earthquake, according to USGS, 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. An earthquake of similar magnitude struck Nepal 80 years ago; in 1934 the Nepal-Bihar earthquake occurred with M=8.0. It severely damaged Kathmandu, and is thought to have caused around 10,600 fatalities. In the coming days USGS expects 3-14 M?5 aftershocks. Additionally, USGS estimates that there is a 54% chance of a M?6 aftershock, and a 7% chance of a M?7 aftershock during this one-week period after the main shock.
