1960 Chile earthquake, also known as the valdivia earthquake, occurred on May 22nd, 1960, which was the largest earthquake recorded in the observation history, with a moment magnitude of 9.5. The earthquake also caused tsunamis to hit Chile, Hawaii, Japan, the Philippines, eastern New Zealand, southeastern Australia and the Aleutian Islands in Alaska. The epicenter was located near Chile, 700 kilometers south of Santiago, and valdivia was the worst-hit city. The tsunami triggered by the earthquake severely hit the coast of Chile, setting off waves as high as 25 meters. The main tsunami crossed the Pacific Ocean and destroyed Hiro. At a distance of 10,000 kilometers from the epicenter, a wave with a height of 10.7 meters was recorded and spread to distant Japan and the Philippines. The number of deaths and economic losses caused by such a large-scale disaster cannot be accurately known. There are different estimates of the death toll caused by the earthquake and tsunami. According to the U.S. Geological Survey, the death toll is 223 1 3,000 or 5,700, and another source estimated that the death toll reached 6,000. [2] Different sources estimate that the economic loss is between 400 million and 800 million dollars. (or add inflation, today it is about $3.2 to $6.4 billion. )
