List of earthquakes in 1957

This is a list of earthquakes in 1957. Only magnitude 6.0 or greater earthquakes appear on the list. Lower magnitude events are included if they have caused death, injury or damage. Events which occurred in remote areas will be excluded from the list as they wouldn't have generated significant media interest. All dates are listed according to UTC time. An extremely active year in a large way helped by a magnitude 8.6 earthquake in Alaska in March. This event was one of the largest on record in the United States and was followed by an energetic aftershock sequence which resulted in 6 aftershocks measuring greater than magnitude 7.0. Other parts of the world such as Mongolia, Bolivia and Turkey to name a few saw large events. Turkey and Iran had several earthquakes with high death tolls.
