A powerful earthquake shook central and southern Mexico on Friday. The US Geological Survey calculated its magnitude at 7.5 and said it was centered near the Pacific resort of Acapulco, where many Mexicans are vacationing for the Easter holiday.

An Associated Press reporter said it was felt strongly in the resort city but there were no immediate reports of injuries or damage.

The quake shook Mexico City for at least 30 seconds, with buildings swaying as people fled high-rises and took to the streets.
