In August and September of 1986, the towns of Crested Butte and Aspen were shaken by a series of earthquakes with Richter magnitudes up to 3.5. Many of the tremors were accompanied by unusual thunder-like sounds. These earthquakes were part of an intense swarm of several hundred events that may have its source along a set of conjugate faults with a system of dikes along the Ruby Range. The fault(s) were probably reactivated in a normal sense by contemporary extensional stresses that characterize much of western and central Colorado.
