List of historical earthquakes
Historical earthquakes is a list of significant earthquakes known to have occurred prior to the beginning of the 20th century. As the events listed here occurred before routine instrumental recordings, they rely mainly on the analysis of written sources. There is often significant uncertainty in location and magnitude and sometimes date for each earthquake. The number of fatalities is also often highly uncertain, particularly for the older events.Source for all events with 'USGS' labelled as the source United States Geological Survey
Note: Magnitudes are generally estimations from intensity data. When no magnitude was available, the maximum intensity, written as a Roman numeral from I to XII, is given.
