The largest earthquake in the world had a magnitude of 9.5 and took place in Chile. The Valdivia Earthquake, also know as the Great Chilean Earthquake, happened on Sunday, May 22, 1960. It is the largest earthquake currently on record. It occured in the afternoon and the resulting tsunami affected southern Chile, Hawaii, Japan, the Philippines, eastern New Zealand, southeast Australia, and the Aleutian Islands in Alaska.

The epicenter of the Valdivia earthquake was near Lumaco, a coastal city with a population of roughly 11,405.

At Corral, the main port of Valdivia, the water level rose 13 ft before it began to recede. A wave of 26 ft struck the Chilean coast, mainly between Concepción and Chiloe. Ten minutes later another wave measuring 33 ft was reported.

Hundreds of people were already reported dead by the time the tsunami struck. One ship, Canelos, starting at the mouth of Valdivia River sank after being moved 0.93 mi backward and forward in the river; its mast is still visible today.
