YUNGAY — 1970 · Major Tragedy

The Huascarán Avalanche That Buried Yungay

ClosedSources: ALast updated: 14 October 2026

On the afternoon of 31 May 1970 a magnitude 7.9 earthquake struck off the coast of Peru. The shaking destabilised the north face of Huascarán, Peru's highest mountain, tearing loose a mass of ice and rock some 900 metres wide. The debris flow travelled about 18 kilometres at speeds of 280 to 335 km/h, burying the town of Yungay and the village of Ranrahirca within minutes. The Ancash earthquake killed between 66,000 and 70,000 people in total, one of the deadliest natural disasters in the Western Hemisphere. The government banned excavation of the old town and declared it a national cemetery; the site, known as the Campo Santo, is now a memorial. Survivors built a new Yungay nearby.
