We have a new earthquake map from the USGS that shows the largest magnitude 8 (or 9) earthquake to hit Colorado in nearly three decades.
The new map, released this week, shows that a magnitude 8 earthquake hit about 1:50 p.m.
Saturday in the Colorado town of Longmont, about 10 miles northeast of the city of Greeley.
The quake was centered about 30 miles (48 kilometers) northeast of Greeleys hometown of West Greeley, Colorado, and about 5 miles (8 kilometers) east of the town of St. George.
A large, shallow, tremor was detected at 1:52 p.n., the US Geological Survey said.
The magnitude 8 quake was felt by at least 30 people in Longmont.
The USGS said the quake occurred between 1:55 and 1:59 p.c. at a depth of about 1.4 miles (2 kilometers).
It is not clear whether the quake was triggered by a fault or natural earthquake.
The quake was the strongest recorded in Colorado since April 2011, when an earthquake measuring magnitude 6.8 struck in the town, triggering a chain reaction that sent rocks and debris crashing into buildings.
