SANTIAGO, Chile -- 
U.S. monitors say a magnitude-6.4 earthquake has struck just off the shore of central Chile, affecting the same area where last year's much larger earthquake set off a devastating tsunami.
Chile's emergency office says Wednesday's quake was a 6.3 and that no damage to people or buildings has been reported.
The U.S. Geological Survey says this earthquake struck just before 9 a.m. (1300 GMT) and was centered 59 miles (96 kilometers) southwest of Concepcion, the capital of Chile's Bio-Bio region.

Earthquake hits southern Spain; damage said unlikely

(CNN) -- A strong earthquake struck near the Spanish city of Granada early Monday, but at a depth that made damage to the medieval Moorish capital unlikely, the U.S. Geological Survey reported.

The magnitude 6.2 earthquake struck at 12:08 a.m. local time Monday (6:08 p.m. Sunday ET), the USGS reported.

It was centered about 24 kilometers (15 miles) southeast of Granada and about 370 kilometers (230 miles) south of Madrid, Spain's capital.

There was no immediate report of damage or injuries from the temblor. The quake's recorded depth of 616 kilometers -- nearly 400 miles -- means little damage is likely, geophysicist Susan Potter told CNN.

Strong quake kills 2 in Mexico, rattles US states

clipped from news.yahoo.com

MEXICALI, Mexico – Aftershocks rattled the southwest Mexico-U.S. border on Monday morning in the aftermath of a major earthquake that killed two people, blacked out cities and forced the evacuation of hospitals and nursing homes.

Sunday's 7.2-magnitude quake, centered just south of the U.S. border near Mexicali, was one of the strongest earthquakes to hit region in decades, shaking at least 20 million people.

It had a shallow depth of 6 miles (10 kilometers). But the human toll was minimal in large part because the energy from the quake moved northwest of Mexicali toward a less populated area, said Jessica Sigala, a geophysicist from the U.S. Geological Survey.

"Construction codes prevented more serious damage," Valdes said. "People see that it always shakes and have improved their construction capacity. Then when the construction codes are implemented, there is stricter control, especially in larger structures."

Minor Earthquake Strikes Near Chicago

CHICAGO—A minor earthquake centered in a rural area about 40 miles north-northwest of Chicago struck in the early hours of Wednesday morning, according to the U.S. Geological Survey.

The 3.8-magnitude quake could be felt as far away as Ohio and Missouri, said Julie Dutton, a geophysicist with the agency.

No damage or injuries were reported, she said, although the USGS did receive 10,000 reports from people who felt the quake. The agency estimated as many as 11 million people felt light shaking. She said the earthquake likely wasn't strong enough to generate any waves on nearby Lake Michigan.
