Earthquake Hazard
... There are three main steps: 1) Define all the possible sources to cause significant hazard at a site using historic data. 2) Choose a fixed distance, fixed magnitude earthquake and place it on the closest position to the site on each source. 3) Estimate ground motions via GMPEs to determine the gr ...

1960 Valdivia earthquake
The 1960 Valdivia earthquake (Spanish: Terremoto de Valdivia) 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 570 kilometres (350 mi) 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 25 metres (82 ft). The main tsunami raced across the Pacific Ocean and devastated Hilo, Hawaii. Waves as high as 10.7 metres (35 ft) were recorded 10,000 kilometres (6,200 mi) 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 US$400 million to 800 million (or $3.19 billion to $6.38 billion today, adjusted for inflation).
