Overview
On 18 April 2014 a catastrophic avalanche struck the slopes of Mount Everest, originating in the Khumbu Icefall and sweeping down toward the established climbing route. The event was triggered by the collapse of a large block of glacial ice (a serac), creating a high-velocity flow of snow and ice that struck climbers and high-altitude workers on the route.
What happened
The avalanche was the result of a serac fall from above the icefall, a common but unpredictable hazard in heavily crevassed glacier terrain. At the time dozens of local guides and climbing staff were working to prepare the route between Base Camp and Camp I when the collapse occurred. The disaster killed 16 people and injured nine others.
Location and characteristics
The Khumbu Icefall sits between Everest Base Camp and Camp I and is composed of constantly moving ice towers and deep crevasses. Seracs are unstable overhanging blocks that can fail without warning, producing avalanches and icefalls. Teams use fixed ropes, ladders and route cutting to cross the icefall, but those precautions cannot eliminate the intrinsic risk.
Immediate response and consequences
Rescue and recovery were carried out under difficult conditions at high altitude. In the days following the incident many expeditions were delayed or cancelled, and debates intensified about the safety, compensation and working conditions for Nepalese guides and porters. The event prompted renewed attention to route selection, acclimatization schedules and the responsibilities of expedition operators.
Notable facts and legacy
- Cause: collapse of a serac above the Khumbu Icefall.
- Impact: 16 dead, nine injured, widespread disruption to the climbing season.
- Aftermath: greater scrutiny of high-altitude safety and the livelihoods of local climbing staff.
