Assuming I have the right earthquake, here is the report. Apparently, CO didn’t suffer any damage:

The 2011 Colorado Earthquake was a magnitude 5.3 (Mw) intraplate earthquake that occurred on August 22, 2011 at 11:46 PM MDT (05:46 UTC). The epicenter was 15 km (10 mi) west northwest of Trinidad, Colorado, and 290 km (180 mi) south of Denver, according to the United States Geological Survey (USGS).[1][3][4][5][6][7][8][9] It was the largest natural earthquake to affect Colorado for more than a hundred years.[4]
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][3] The 5.3 magnitude earthquake occurred as a result of normal faulting and was similar in depth, style and location to the events that made up the 2001 swarm.
Impact[edit source | editbeta]

Tremors were felt around the state of Colorado and in areas of New Mexico.[10]
A Las Animas County Sheriff's Office dispatcher said she had received calls from "tons" of county residents who felt the shaking, as well as reports of rockslides along a highway following the quake. USGS geophysicist Jessica Sigala said the quake has the potential of causing minimal damage.[10]
Another USGS geophysicist, Shengzao Chen, said the center had received calls from more than 70 people in Trinidad, Colo., who felt the shaking, as well as several dozen people in New Mexico. More than 30 people in Colorado Springs, about 130 miles from Cokedale, also reported feeling the quake, he said.[10]
