Welcome to our Earthquake Catalogs! 

These catalogs are lists of Oklahoma earthquakes (and important details regarding each earthquake) organized over a certain period of time. They are fairly complete to a minimum magnitude of 2.9 from 1980 to present, a minimum magnitude of 3.6 from 1960 to present, and a minimum magnitude of 5.0 from 1897 to present. Each catalog has many downloadable file formats. Refer to this table for descriptions of file types and application compatibilities.
