Strongest Earthquake of the Year in Western Colorado Overnight
An earthquake measuring 4.3 on the Richter Scale was recorded in western Colorado overnight. The quake was centered in Rio Blanco County just a few miles from the location of an underground nuclear test site in the 1970s, and was one of four to occur in or near Colorado over the past 24 hours.
The United States Geological Survey reports that the earthquake occurred shortly after 4:00 a.m. in a sparsely populated area about 50 miles north of Grand Junction at a depth of more than three miles.
