Earthquakes were reported early Tuesday morning south of Mexico City, but there have been no reports of injuries or significant damage.
The U.S. Geological Survey reported a magnitude-5.5 quake occurred at 7:04 a.m. local time, centered about 10 miles west-southwest of Pinotepa Nacional on the Pacific Coast and 227 miles south-southeast of Mexico City. Mexico Seismology Service initially calculated the quake's magnitude at 5.9.
A second quake shook the region a few minutes later.
Mexico City's soft soil makes it especially sensitive to distant earthquakes. But Mayor Manuel Mancera said in a Twitter post that no damage was reported.
Local news media also said there were no reports of damage close to Pinotepa Nacional.
