The Assistant Secretary of State for South and Central Asia, Nisha Desai Biswal, said the US is working through USAID's Office of US Foreign Disaster Assistance (OFDA) to provide assistance to earthquake victims in Nepal.
US OFDA chief Jeremy Konyndyk said USD 1 million has been authorised to address immediate needs.
"USAID, OFDA is launching a DART (disaster assistance response response team) to respond to the Nepal quake and has authorised an initial USD 1m to address immediate needs," he wrote on twitter.
"The President has been briefed (on the earthquake)," a White House official told PTI when asked about the earthquake.
The quake measuring 7.9 on Richter scale, which was followed by 16 aftershocks of magnitude 4.5 or greater, killed nearly 1,500 people in Nepal and left several thousands injured and hundreds missing across the country.
