This is a list of earthquakes in 1921. 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. In a stark contrast to 1920, the death toll for this year was only 51. Indonesia and Japan were very active.
