Intense Video Shows the Terrifying Moment an Avalanche Hits Mount Everest

Warning: this video contains profanity.

Mount Everest was one of the places hit hard by the devastating earthquake in Nepal on Saturday. At least 18 people died at the base camp — including a Google executive named Dan Fredinburg — after the quake triggered an avalanche. Now a video has surfaced showing the moment the avalanche started roaring toward hikers, and it's quickly gone viral. "The ground is shaking" is the first thing you hear German climber and videographer Jost Kobusch say. About 19 seconds into the video, he sees other people running and realizes the avalanche is coming before he ducks into a tent with fellow climbers.

"The ground was shaking from the earthquake and as soon as we saw people running we were running ourselves to save our lives," Kobusch wrote on YouTube. It's hard to watch the video without your heart racing: just imagine what it was like to be there in person.
