The 1960 Valdivia earthquake () or Great Chilean earthquake (''Gran terremoto de Chile'') of Sunday, 22 May 1960 was the most powerful earthquake ever recorded, rating a 9.5 on the moment magnitude scale. It occurred in the afternoon (19:11 GMT, 15:11 local time), and lasted approximately 10 minutes. The resulting tsunami affected southern Chile, Hawaii, Japan, the Philippines, eastern New Zealand, southeast Australia and the Aleutian Islands. The epicenter was near Lumaco (see map), approximately south of Santiago, with Valdivia being the most affected city. The tremor caused localised tsunamis that severely battered the Chilean coast, with waves up to . The main tsunami raced across the Pacific Ocean and devastated Hilo, Hawaii. Waves as high as were recorded from the epicenter, and as far away as Japan and the Philippines. The death toll and monetary losses arising from such a widespread disaster are not certain. Various estimates of the total number of fatalities from the earthquake and tsunamis have been published, with the United States Geological Survey citing studies with figures of 2,231, 3,000, or 5,700 killed and another source using an estimate of 6,000 dead. Different sources have estimated the monetary cost ranged from 400 million to 800 million〔 (or $ to $ today, adjusted for inflation). ==Earthquake development== The 1960 Chilean earthquakes were a sequence of strong earthquakes that affected Chile between 21 May and 6 June 1960.
