What was the magnitude of the earthquake in Chile May 22 1960?
Actions that saved lives, and actions that cost lives, as recounted by eyewitnesses to the tsunami from the largest earthquake ever measured – the magnitude 9.5 earthquake in Chile on May 22, 1960.
Why was the Valdivia earthquake so strong?
It is subducting under (that is, being forced under) the South American plate. A sudden breaking in the rocks along a roughly 560–620-mile (900–1,000-km) stretch of the Nazca Plate caused the earthquake, which has been generally agreed to have had a magnitude of 9.5—the largest earthquake recorded in the 20th century.
Was the Valdivia earthquake Richter scale strong?
The 1960 Valdivia earthquake and tsunami (Spanish: Terremoto de Valdivia) or the Great Chilean earthquake (Gran terremoto de Chile) on 22 May 1960 was the most powerful earthquake ever recorded. Various studies have placed it at 9.4–9.6 on the moment magnitude scale.
What caused the Valdivia earthquake 1960?
