Three small earthquakes rattled parts of central Arizona and were felt in the Phoenix area.
The U.S. Geological Survey says a magnitude 4.1 temblor struck at 11:29 p.m. MST Sunday, followed by a 4.0 quake about 20 minutes later. A smaller, magnitude-3.2 quake, hit at 9 p.m.
The USGS says all the quakes ranged from 3-6 miles in depth and were centered near Black Canyon City, about 45 miles north of Phoenix.
The agency's website recorded scores of responses from people in such suburban Phoenix cities as Cave Creek, Peoria, Scottsdale and Glendale who reported feeling at least one of the quakes.
The sheriff's offices in Yavapai County and Maricopa counties didn't immediately comment when contacted about the quakes.
