A powerful, magnitude 7.2 earthquake has shaken central and southern Mexico.

The U.S. Geological Survey initially calculated the quake's magnitude at 7.5, but later downgraded it to 7.2. It says the quake was centered northwest of the pacific resort of Acapulco, where many Mexicans are vacationing for the Easter holiday.

The quake was felt strongly in the resort city, as well as in Mexico's capital.

A woman who answered the phone at the civil protection office in Acapulco says officials are patrolling the city to check for damage and causalities.

There have beden no immediate reports of injuries or damage.

The quake was centered 170 miles southwest of Mexico City, but the shaking was felt in the capital for at least 30 seconds. Buildings swayed as people fled high rises and took to the streets.
