Rio Blanco County experienced its third earthquake in a day Saturday as a magnitude 3.4 quake shook an area approximately 50 miles north of Grand Junction.
The quake occurred at 4:42 a.m. and was about one mile beneath the surface. It was located about four miles southwest of a 4.3 earthquake that occurred Friday morning. That quake was the strongest of the year in Colorado so far. A magnitude 2.9 quake was also recorded in the area Friday by the United State Geological Survey.
