Climbers at the base camp of Mount Everest run for cover as a huge avalanche triggered by the Nepal earthquake approaches.
Cries of “inside, inside!” and “close the door” are heard, followed by rapid breathing as the climbers huddle inside a tent.
The panic is captured on amateur video, one of several to emerge showing the moment Nepal’s calamitous earthquake struck last Saturday.
The avalanche wiped out a large part of the base camp, killing 18 climbers and mountain sherpa guides and injuring more than 60 people.
But it narrowly missed these climbers’ tent. Paul Devaney and Teodor Johansen, who filmed the video, say everyone in it is safe and well.
“I’ve never seen anything like that before,” one said with relief.
At Tripureshwor Chowkin in southern Kathmandu, CCTV footage captured the scene as a monument in the middle of a roundabout collapsed and tumbled into the road.
A tourist filmed the events unfolding in Bhaktapur, the UNESCO World Heritage Site known for its mostly Hindu temples and historical architecture.
As people in Durbar Square watch in fear and awe, bricks and debris fall from the surrounding monuments and dust fills the air.

As well as a tourist attraction, Bhaktapur is also a normal city of some 300,000 people. Nearby in the old backstreets, many buildings were reduced to rubble, hundreds were killed.
One local was quoted as saying more than half of people in the city were affected by the earthquake.
