Historical earthquakes is a list of significant earthquakes known to have occurred prior to the early 20th century. As the events listed here occurred before routine instrumental recordings — later followed by seismotomography imaging technique,[1] observations using space satellites from outer space,[2] use of artificial intelligence (AI) for early earthquake warnings[3] — they rely mainly on the analysis of written sources, observations of shaking objects and/or animal behavior during earthquakes,[4] religious/traditional beliefs about earthquakes such as "God's punishment", "God's rage", "Earth's rage" or "Mother Nature's rage".[5] There is often significant uncertainty in location and magnitude and sometimes date for each earthquake. The number of fatalities is also often highly uncertain and hypothetical, particularly for the older events.
