Filmmaker Michael Churton has described the moment he was hit by an avalanche while climbing Mount Everest.
The 38-year-old from New York says he believes that the force of the earthquake shook loose a big ice shelf, which careered down the mountainside towards him and a group of people he was with.
"I told the group to get down. It was about 4,000 feet of snow just coming and there was nowhere to run," he said.
As the tsunami of snow approached, he got into the foetal postition and hoped for the best.
The force of the snow hitting his body knocked him into a rock, leaving him with some facial injuries.
After about a minute of snow pummelling over him, Mr Churton managed to dig himself out and search for his companions.
He described how someone next to him had been pushed 30 feet away, while another woman remains missing.
It comes as German mountaineer Jost Kobusch captured the terrifying moment the Everest base camp was hit by an avalanche triggered by the Nepal earthquake.
Other survivors on Everest described a cloud of rock and ice that smashed into base camp on Saturday.
Mountaineer Alex Gavan posted this to Twitter:
More than 60 people were injured, leading climbers to send frantic messages calling for helicopter assistance to evacuate the wounded.
An estimated 100 climbers and guides were safe but trapped at camps 1 and 2 by Saturday's 7.9 magnitude earthquake which rendered the treacherous Khumbu icefalls leading up to them from base camp impassable.
