The 2011 Colorado earthquake occurred on August 22 at with a
moment magnitude of 5.3 and a maximum
Mercalli intensity of VII (Very Strong ). The
epicenter of the
intraplate earthquake was 10 mi (20 km) west northwest of
Trinidad, Colorado , and 180 mi (290 km) south of
Denver , according to the
United States Geological Survey (USGS).

[6] It was the largest natural earthquake to affect Colorado for more than a hundred years.
[3]
The earthquake occurred as part of a
swarm of smaller quakes that started the previous day. The last time the Colorado region received a series of earthquakes was in 2001, when about a dozen smaller-sized temblors were recorded.
[1] The shock occurred as a result of
normal faulting and was similar in depth, style and location to the events that made up the 2001 swarm.
