Mexico City Buildings Shake in Strongest Earthquake Since 2003

Buildings in Mexico City swayed, sending frightened residents into the streets of the capital, after a 7.4-magnitude earthquake struck near Acapulco.

President Felipe Calderon, in a message posted on Twitter, said no major damage had been detected and there were no reports of casualties. The quake, which was originally estimated by the U.S. Geological Survey to have a 7.9 magnitude, struck 200 miles southeast of the capital in Oaxaca state.
