Most recently, E. Engdahl and A. Villasenor completed a global earthquake catalog for the 20th century with o events.
This is the most complete and uniform earthquake catalog based on instrumental data available today. The hypocentral and focal mechanism catalogs are produced by the Alaska Earthquake Center () and contain seismicity records and focal plane solutions for historic events dating back to The seismic network is most densely concentrated in southern Alaska to monitor activity on crustal faults, the subduction zone, and along the Aleutian Islands.

Listed below are all the 35 known earthquakes with an estimated magnitude of or higher since Limited to a timeframe with enough data, this gives a rough estimate of its frequency per century. (The timeframe does not include outlying events like the earlier Shōhei earthquake and Sanriku earthquake, both estimated to have magnitude ≥ ).
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.
