This is a list of earthquakes in 1903. 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. A quieter year than normal but one with many deaths. The bulk of the deaths in this year came from a quake which struck Turkey in April. The largest event of the year was a magnitude 8.1 earthquake in Greece but this only caused two deaths.
