Acapulco Quake: U.S. Geological Survey 7.6 Acapulco earthquake, A major 7.6 magnitude earthquake has struck 200 km (120 miles) east of Acapulco on Mexico’s Pacific coast.

The quake was felt in Mexico City where buildings shook and office employees fled into the street, according to witnesses. Cell phone lines were down and traffic snarled in the capital moments after the quake.

The U.S. Geological Survey located the epicenter of the quake at 525 km (15 miles) east of Ometepec in Guerrero state at a depth of 18 km (10.9 miles).

No damage was reported in Oaxaca, near where the quake hit, according to local television.

The Pacific Tsunami Warning Center said the inland earthquake would not generate a destructive widespread tsunami, but there was the possibility of some local tsunami effects.

U.S. Geological Survey, A 5.6 magnitude earthquake struck in Oklahoma late on Saturday evening, the U.S. Geological Survey said, toppling a chimney, damaging buildings and sending a boulder the size of an SUV onto a rural road.

The quake was the strongest in Oklahoma history, topping a tremor of 5.5 magnitude in 1952, according to the USGS.

It was the second quake recorded in the state within 24 hours after a tremor of 4.7 magnitude early on Saturday. Both quakes were centered east of Oklahoma City in Lincoln County.

There were no reports of serious injuries or deaths.

J.L. Gilbert, owner of the Sparks Vineyard and Winery, about four miles from the epicenter of the quake, said it lasted “a good 30 seconds.”

“It was a pretty good jolt. We’re not used to this. We’re used to being sucked up into the wind,” he said, referring to Oklahoma’s reputation as a tornado alley.

One of Gilbert’s employees went to the hospital after tripping and hitting his head on a doorway while scrambling to get out of his home, Gilbert said.

In Prague, Oklahoma, where the earlier quake was centered, City Manager Jim Greff said the latest tremblor caused a chimney to topple over and crash through the roof of a home.

Part of the ceiling grid in the Prague library collapsed during the quake, but the walls remained intact, Greff said.

The earthquake caused state Highway 62 to buckle in three places west of Prague and sent a boulder “about the size of an SUV” tumbling onto a rural road in southeast Lincoln County, said Aaron Bennett, dispatch supervisor for the county’s emergency management division.

Four aftershocks from the initial quake were felt by 1 a.m. Sunday, Bennett said.
