The earthquake occurred approximately nine miles southwest of Trinidad, Colo.

This was the largest earthquake in Colorado since a M5.3 in August, 1967 at Rocky Mountain Arsenal. The largest earthquake in Colorado history was Nov 7th, 1882, near Rocky Mountain National Park; estimates vary but it was about a Magnitude 6.5.

Yesterday's M5.3 had three detected foreshocks (M4.6, 3.0 and 2.9), and there have been many recorded aftershocks.

Citizens who felt the earthquake can go online and report their observations on the USGS Did You Feel It? Web site (http://earthquake.usgs.gov/eqcenter/dyfi/). Over 1,000 reports of felt shaking have already been received from more than 200 zip codes in six states.

Earthquakes cannot be predicted. This area in Colorado has a history of earthquakes, notably a swarm that occurred in 2001, with earthquake magnitudes between M2.9 and 4.6. A USGS report on those earthquakes is available at the USGS Earthquake Hazards Program website (http://pubs.usgs.gov/of/2002/ofr-02-0073/ofr-02-0073.html).
