MEXICO CITY (AP) - An earthquake shook Mexico's capital Friday and Mexican authorities has reported a moderate magnitude of 5.3. There are no reports of damage or injuries.
Many office workers evacuated their buildings after the quake set off alarms citywide.
Mexico's national seismology service says the quake was centered in the southern state of Guerrero.
Mayor Miguel Angel Mancera says in a message from his Twitter account there are no immediate reports of damage or injuries.
Mexico City is vulnerable to distant earthquakes because much of it sits atop the muddy sediments of drained lake beds. They jiggle like jelly when 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 (400 kilometers) away on the Pacific Coast.
