RANGELY — A small earthquake was recorded about 11:30 a.m. Thursday about three miles from Rangely.

The tremor, which measured 2.8 in the Richter scale, was felt by a few people, who posted their experience on the Rangely Buy, Sale and Trade Facebook page. One resident said it felt as though something had hit her house and asked if anyone else had noticed, inspiring more than 20 comments.

Saturday’s temblor marked Northwest Colorado’s third earthquake this year.

Two other tremors shook residents up in April. About 2:45 a.m. April 20 a magnitude 3.9 quake hit roughly 22 miles northwest of Craig.

Two days later, about 11 a.m. April 22, another shock originated roughly 3 miles west, northwest of Rangely, and measured 3.7 in magnitude.

“Typically a magnitude 3.0 to 3.9 event would be only slightly felt as a vibration, maybe similar to that of a passing truck. People on upper floors of buildings would notice it more,” said Matt Morgan, deputy director and senior research geologist for the Colorado Geological Survey.

Minor earthquakes such as these are not unusual in Western Colorado, said Julie Dutton, geophysicist for the national earthquake center national earthquake center in Golden.
