The deadly avalanche that swept through the Mt. Everest base camp after Saturday's massive earthquake in Nepal was caught on video by a German climber. "The ground is shaking," someone shouts as the footage begins. Moments later, climbers in the distance begin to run before the avalanche itself is visible. Then, within seconds, the camera fills with a fast-moving cloud, signaling the advance of the avalanche. The climbers shout and duck into tents as the rumble of the avalanche moving past can be heard outside. The footage was posted on Youtube by Jost Kobusch, a climber from Germany who previously has posted clips about preparations for his expedition.
