A team of more than 60 search and rescue responders and medical experts has been deployed to support the relief effort in Nepal, International Development Secretary Justine Greening said.
A Department for International Development-chartered flight is leaving London tonight for Kathmandu, carrying seven UK International Search and Rescue crews, four search and rescue dogs, a medical support team and a hazardous materials specialist.
They will take with them more than 11 tonnes of kit, including torches, axes, rope, search cameras, stretchers and tents.
Also on board will be trauma medics travelling as part of a DFID-deployed UK Med team and a five-strong Foreign Office Rapid Deployment Team.
ITV News' Political Correspondent Lewis Vaughan Jones reports:
Four men trapped under as much as 10 foot of rubble after the Nepal earthquake were rescued when NASA technology sensed their heartbeats.
One medical worker told ITV News it was like 'entering your worst nightmare' as they tried to help look after the injured.
