CLIFTON, Ariz. -- A 4.1-magnitude earthquake struck near the Arizona and New Mexico border, and officials say it was the largest in a series of aftershocks from a temblor last month.
The U.S. Geological Survey said the quake struck at 7:48 p.m. PDT Friday and was centered about 40 miles south of Clifton and 5 miles west of the New Mexico border.
The Greenlee County Sheriff's office in Clifton said it hasn't received any calls from people reporting the quake.
USGS geophysicist Dale Grant said it was the largest of many aftershocks from a magnitude 5.2 quake that struck in the same area on June 28. That quake was widely felt but caused no injuries or serious damages.
The Arizona Geological survey said aftershocks could hit the area for weeks or even months.
