On the afternoon of April 15, 2015, an earthquake rocked the Himalayas, causing widespread death and damage across Nepal, India and Tibet. The magnitude 7.8 quake—the strongest ever recorded in the region—rattled glaciers and ice falls along a ridge just to the west of Mount Everest, sending an avalanche of ice and snow hurtling towards the base camp below. When the snow settled, 15 were dead and scores more were injured in what would become the deadliest day on the world's highest mountain.
