Mexico City earthquake 2013: No word of damage, injuries

MEXICO CITY (AP) - A seemingly strong earthquake is shaking Mexico's capital.

The magnitude-6.1 quake struck about 167 miles south of Mexico City, close to the resort city of Acapulco, just before 8:40 a.m. Eastern time.

Mexico City is vulnerable even to distant earthquakes because much of it sits atop the muddy sediments of drained lake beds that quiver as quake waves hit.

The magnitude-8.1 quake in 1985 that killed at least 6,000 people and destroyed many buildings in Mexico City was centered 250 miles away on the Pacific Coast.
