On November 7, 1882 an earthquake rocked parts of Colorado, Wyoming, Utah, and
Kansas. It was felt over 470,000 sq km , with a maximum reported Modified Mercalli intensity of VII. An isoseismal map for the main event and the felt area of an aftershock on November 8th, along with historic wave path and
focusing considerations, suggest the epicenter was probably in north-central Colorado, perhaps in the northern Front Range or possibly southern Laramie Mountains.
