4.1 magnitude earthquake rocks the valley

PHOENIX (KSAZ) - A 4.1 magnitude earthquake rocked the valley near Black Canyon City on late Sunday night. 

The United States Geological Survey tells Fox 10 that three small earthquakes hit the area of Black Canyon City beginning at around 9:30 p.m. on Sunday night. The largest of the three, a 4.1 magnitude earthquake, hit just northeast of Black Canyon City at 11:30 p.m., and was likely an aftershock of an earlier earthquake, according to the National Weather Service.

The first earthquake that hit the area was 3.2 magnitude, followed by a 4.0 about five kilometers northeast of Black Canyon City, a rural mountain community about 45 miles north of Phoenix.

The three quakes were a fairly routine release of stress underground, said David Brumbaugh, a Northern Arizona University geophysics professor and the Arizona Earthquake Center's director. 

Power outages rocked the valley, however, APS now says they have no reason to believe the outages were a result of the earthquakes.

All power was restored as of 1:43 a.m. on Monday morning.

The Arizona Department of Transportation says no bridges or tunnels were affected by the earthquakes.
