The 1960 Valdivia earthquake and tsunami (Spanish: Terremoto de Valdivia) or the Great Chilean earthquake (Gran terremoto de Chile) occurred on 22 May 1960. Most studies have placed it at 9.4–9.6 on the moment magnitude scale, making it the strongest earthquake ever recorded, while some studies have placed the magnitude lower than 9.4. It occurred in the afternoon (19:11:14 UTC, 15:11:14 local time), and lasted 10 minutes. The resulting tsunamis affected southern Chile, Hawaii, Japan, the Philippines, eastern New Zealand, southeast Australia, and the Aleutian Islands. The epicenter of this megathrust earthquake was near Lumaco, approximately 570 kilometres (350 mi) south of Santiago, with Valdivia being the most affected city. The tremor caused localized tsunamis that severely battered the Chilean coast, with waves up to 25 metres (82 ft).
