A powerful earthquake shook central and southern Mexico on Friday. Mexico's seismology service calculated the magnitude at 7.0 and said it was centred near the resort city of Acapulco. The US Geological Society (USGS) is reporting the quake as a magnitude of 7.5.
There was no immediate word of damage or casualties.
The quake shook Mexico City for at least 30 seconds, with buildings swaying as people fled high rises and took to the streets. Because of the Easter holiday, that city was less crowded than usual.
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 centred 250 miles (400 kilometres) away on the Pacific Coast.
