The U.S. Geological Survey's National Earthquake Information Center in Golden, Colorado says an earthquake shook the eastern San Luis Valley Wednesday.
The 2.7-magnitude earthquake occurred just before 10:30 Wednesday morning. Its epicenter (the ground's surface immediately above the earthquake's center) was about 22 miles east-northeast of Alamosa and very near Blanca Peak. It was 65 miles southwest of Pueblo and occurred at a depth of about 2 miles. No damage has been reported, and no reports have been received that anyone felt the tremor.
The U.S. Geological Survey notes that while earthquakes are rare in Colorado, little is known about the state's earthquake history due to the short period of earthquake records here. The majority of Colorado's earthquakes historically have been reported west of the Front Range. Most earthquakes east of the Front Range have been along the Arkansas River Valley and the South Platte River Valley.
Colorado's largest earthquake on record was a 6.6-magnitude quake that struck on November 7, 1882 and was centered around present-day Rocky Mountain National Park. It caused damage at the University of Colorado campus in Boulder and was the first earthquake on record to cause damage in Denver. It was felt as far away as Salt Lake City to the west and Salina, Kansas to the east. Other sizable earthquakes are known to have occurred near Buena Vista and Montrose.
