Two quakes shake Boulder

Two weekend earthquakes did not go unnoticed by many Boulder residents.

The first, at 2.8 magnitude, occurred about 7 p.m. April 17; the second, at 2.6, before noon on Sunday. Each quake originated in roughly the same area, about three to four miles east, northeast of Boulder, and about six miles deep, according to the United States Geological Service.

Friday’s quake was preceded by two smaller earthquakes from the same general area earlier that day, registering 2.1 and 1.4. A slightly smaller quake immediately followed the 2.8 event, registering at 2.5, according to the USGS.
