List of earthquakes in 1918

This is a list of earthquakes in 1918. 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. A couple of major events capped a fairly active year. The two major events came within weeks of each other. The largest was a magnitude 8.3 in the Philippines in August. In early September a magnitude 8.1 struck Russia. The deadliest event occurred in February in China when a magnitude 7.3 caused 2,000 deaths.
