Largest Earthquake Ever Recorded?

The question that I wanted to answer was "What was the largest earthquake ever recorded?". See below for the information I found out:

The largest earthquake ever recorded was in Valdivia in Chile. It occurred on the 22^nd May 1960 and was recorded at 9.5 on the Richter scale. It occurred in the afternoon at 15:11 local time. The earthquake also resulted in a tsunami which affected southern Chile, Hawaii, Japan, the Philippines, eastern New Zealand, southeast Australia and the Aleutian Islands in Alaska. The epiccenter was near Lumaco around 570km south of Santiago. The waves reached up to 25m in height. Two days after the earthquake, a volcanic vent close to Puyehue volcano erupted. This was caused by the Nazca Plate being subducted underneath the South American Plate on the Peru-Chile Trench.
