5.3-magnitude earthquake in Colorado late night August 22
The USGS is reporting a series of eight earthquakes – including a magnitude 5.3 midnight earthquake – that shook southern Colorado beginning Monday morning local time, August 22, 2011. The largest of these eight quakes came last night (August 22) just before midnight local time. The 5.3-magnitude quake woke some people up and startled hundreds of others, including some in Colorado Springs, according to Associated Press and a report in the Colorado Springs Gazette.
The 5.3-magnitude quake took place Monday, August 22, 2011 at 11:46:19 p.m. local time (5:46 UTC on August 23). Its epicenter was 15 kilometers (9 miles) west-southwest of Trinidad, Colorado and 290 kilometers (180 miles) south of Denver, Colorado.
U.S. Geological Survey geophysicist Amy Vaughn told the Colorado Springs Gazette that the midnight 5.3-magnitude quake is the largest in Colorado since a magnitude 5.7 was recorded in 1973.
The Colorado Springs Gazette also reported that a few homes were damaged, and local sheriff’s deputies were investigating reports of rockslides along highways.
The last time the area received such a series of earthquakes was in August and September 2001, when about a dozen smaller-sized temblors were recorded
