An earthquake measuring 3.8 on the Richter Scale struck just inside Colorado along the border with New Mexico early Sunday morning in Las Animas County.

According to the United State Geological Survey, the quake struck at 4:43 a.m. and was centered about 27 miles southwest of Trinidad. It occurred at a depth of nearly five miles beneath the surface. No damage or injuries have been reported.

The area is known for minor earthquakes. Since the start of the year, seven earthquakes measuring 2.0 or greater have been recorded in the area, including one on May 5. Six quakes were recorded nearby in Alamosa and Huerfano counties between February and March. The strongest in that area measured 3.4 but was originally reported being as strong as 3.8.

Colorado has experienced 37 earthquakes measuring 2.0 or more since January 1. Most have occurred in the southern and western parts of the state, though two small quakes were recorded near Greeley in late March.
