List of earthquakes in 1906

This is a list of earthquakes in 1906. Only magnitude 6.0 or greater earthquakes appear on the list. Exceptions to this are earthquakes which 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. This year saw a number of historic earthquakes of which their significance was felt for many years after.

• A magnitude 6.5 earthquake struck Fujian Province, China on March 28 at an unknown depth. There were many (at least 101) deaths, some (at least 51 injuries) and a moderate amount of damage.

April–June

• A magnitude 7.2 earthquake struck the Revilla Gigedo Islands, Mexico on April 10 at a depth of 0.0 km.
• A magnitude 7.1 earthquake struck Chiayi County, Taiwan on April 13 at a depth of 5.0 km. There was 15 people killed, 84 further injured and the destruction of 1,794 homes.
• A magnitude 6.9 aftershock struck Chiayi County, Taiwan on April 13 at a depth of 5.0 km. This being a similar magnitude to the main shock means that it could be classed as a doublet earthquake.
• A magnitude 7.7 earthquake struck the San Pablo Bay, California on April 18 at a depth of 10.0 km. This event was the worst in California's history in terms of the death toll which ranges from 700 to an estimated 3,000. The fire which followed contributed to the death and damage count. Approximately 28,188 homes were destroyed and damage costs came to approx $400–530 million. No other earthquake has since surpassed this event in terms of magnitude in California as of November 2015.
