Small earthquake shakes east Arizona

Posted: Updated:

PHOENIX -- A small earthquake has shaken eastern Arizona near its border with New Mexico.

The U.S. Geological Survey say the magnitude 3.7 temblor struck at 12:27 a.m. Monday and was centered about 160 miles east of Phoenix.

The earthquake zone was in a sparsely populated area and the USGS said on its website that it had very few reports of anyone feeling it.

Small quake shakes US-Mexico border; no damage

OCOTILLO, Calif. -- Another small earthquake has struck an often shaken border region of California and Mexico, but there are no reports of any injuries or damage.

A preliminary report from the U.S. Geological Survey says the magnitude-4.2 quake struck at a depth of about 11 miles at about 10:20 p.m. Sunday. It was centered 21 miles west of Mexicali, Mexico, and 12 miles southeast of Ocotillo, Calif.

A dispatcher with the Imperial County Sheriff's Department says no injuries or damages have been reported.

The earthquake shook the same region as a magnitude-7.2 quake that killed two people in Mexicali April 4. The region has seen a major surge in seismic activity since.
