List of earthquakes in 1922
This is a list of earthquakes in 1922. 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. The dominant event of the year both in terms of magnitude and death toll was in Chile. In November a magnitude 8.5 earthquake struck the Atacama Region. This was one of the largest events of the 20th Century. In spite of the magnitude only 700 deaths were caused. Peru, Russia and Taiwan had several magnitude 7.0+ events.
