Forty-five earthquakes of moderate intensity (V or greater) on the Modified Mercalli Intensity Scale (MM) and extent have originated in Wyoming from 1894 to 1976. Many shocks have occurred in Yellowstone National Park, including an intensity VII event in June 1975. the 1959 Hebgen Lake, Mont., earthquake, centered just west of the park, was felt (MM VII) in northwestern Wyoming. Many aftershocks from this earthquake were reported in Yellowstone Park (MM V-VI) through December 1959, and numerous shocks of lesser intensities continued through 1963.

Earthquake history of Virginia

Virginia is a State of considerable seismic activity, although the earthquakes are rarely strong. Thirty-five shocks, intensity MM V or greater (Modified Mercalli Scale), are listed with epicenters within its borders. The locations of several of the older events are not precise; thus, the above count i subject to alteration. A detailed study of Virginia earthquakes by G. A. Bollinger and M. G. Hopper of the Virginia Polytechnic Institute and State University listed 137 shocks (71 from 1774 to 1899, 66 from 1900 to 1970). Many of these were felt with intensities below MM V.

Earthquake history of Vermont

Seven earthquakes of intensity V or greater on the Modified Mercalli Scale (MM) are known to have originated within Vermont. Many additional shocks centered in other New England States and Canada have been strongly felt in Vermont.
