The quake was at a depth of 10 kilometers.
Since 1900, several earthquakes of magnitude 8 and larger have occurred in the region, some resulting in destructive tsunamis. In 1960, a magnitude-9.6 earthquake in southern Chile was the largest instrumentally measured quake in the world, according to the USGS.
In 2010, a magnitude 8.8 earthquake was reported just north of the 1960 quake.
