A major 7.6 magnitude earthquake struck 120 miles east of Acapulco on Mexico's Pacific coast, the U.S. Geological Survey reports.
In Mexico City, the temblor shook buildings and sent people flooding into the streets, the Associated Press reports. Cell phone lines went down and traffic jammed in the moments after the quake, but the president said there were no immediate reports of major damage. The Post’s correspondent in Mexico, Nick Miroff, felt the quake:

The quake was followed by a less powerful aftershock that was also felt in Mexico City.
The Pacific Tsunami Warning Center told Reuters that the quake would not generate a destructive tsunami, but that there could be some local tsunami effects.
