Earthquake activity ramps up in southeastern Arizona

There have been at least 22 small earthquakes in the last 24 hours south of Duncan in southeastern Arizona, near the New Mexico border, according to Dr. Jeri Young, who manages the state seismic monitoring network here at AZGS.   A magnitude 3.0 earthquake at 8:22 a.m. today is the largest one detected.  There are reports of shaking being felt  by residents in the area.   [Right, orange star marks the epicenter of the M=3.0 event.

The earthquakes are occurring in the same area that experienced a magnitude 5.3 quake in June 2014.   Aftershocks have continued in the area since then.
