David Breashears, an American filmmaker was on Everest working for the climate change awareness organisation GlacierWorks at the time the earthquake struck.

"We were preparing a brew, it was around noon and I was the first to notice it [...] It was very confusing at first, and then the shaking became much more violent, I think it lasted around 60 seconds", he told 5live's Up All Night programme.

Breashears explained that the two men knew that ice and snow would "soon begin raining down into the camp".

"Our instincts were to get out of the tents and see where the threat was coming from and not be buried alive in our tents [...] we took shelter wrapping our arms around each other, awaiting our fate".

The two men waited the avalanche out before getting on their radio to hear "the terrible news from base camp".
