Colorado was jolted by a 5.3 magnitude earthquake on Monday. The earthquake, which struck at 11.46 p.m. local time, is the largest since 1973 when the state was struck by a 5.7-magnitude quake.
The latest earthquake was recorded at 9 miles southwest of Trinidad, Colorado, 19 miles northwest of Raton, New Mexico and 182 miles of Denver, Colorado, according to the National Earthquake Information Center.
No injuries have been reported but State officials said that a number of homes around the epicentre have suffered minor structural damage. The earthquake was followed by an aftershock of 3.2 magnitude.
Earthquakes everywhere occur on faults within bedrock, usually miles deep. Most of the region's bedrock was formed as several generations of mountains rose and were eroded down again over the last billion or so years, according to United States Geological Survey (USGS).
