Historic Earthquakes in the United States and Its Territories

We're transitioning to a new system. Most earthquakes and associated information are in the new ComCat Earthquake Catalog, which the new Significant Earthquake Archives uses.

If you're looking for some particular information associated with an earthquake that you don't see on the eventpage for the earthquake in the Significant Earthquake Archives, return to this page and try the earthquake link in this list.

Thanks for your understanding while we're transitioning all the information.

Sorted by Date

Selected earthquakes of general historic interest.
All earthquake dates are UTC, not local time.
