Deadly Everest avalanche triggered by Nepal earthquake which took life of 7802 fo far.Climbers at the Mount Everest base camp – and others trapped higher on its slopes – were locked in a desperate effort to treat injured colleagues caught in a devastating avalanche that swept through the encampment after being triggered by Saturday’s powerful earthquake. Nepal was also hit Sunday by a series of aftershocks, triggering more avalanches in the mountains above base camp. None of those avalanches, though, were believed to have caused further injuries.
