This is a list of earthquakes in 1920. 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. With over 200,000 deaths being recorded in China, and substantial fatalities elsewhere, 1920 was one of the deadliest years of the 20th century for earthquakes.
