Writing on their blog a few hours after the devastation, Schneider and Chappatte said Saturday was "very, very scary". Their part of the original Base Camp had been flattened.
The drama was one of many incredible stories of survival that emerged yesterday after the devastating earthquake and avalanche.
Nine Greek climbers whose Sherpa guide stole from them in Kathmandu told of their lucky escape after heading home from Nepal the day before the avalanche.
"We arrived in Kathmandu last week and there we discovered that our Sherpa had disappeared with the money we had given him," one of the climbers told Nerit, Greek public TV.
"In the end we were lucky, but we have friends at the [Everest] camps who are living through very difficult moments," he added.
A Northampton archaeologist and her friend survived an "apocalyptic nightmare" when the village they had been in two hours earlier was flattened. Dr Hayley Saul, 32, was said to be "absolutely terrified".
Her sister, Emma Price, 24, said: "They had to trek another five or six hours to get to the next village. Huge boulders were falling and following them."
