An 8.1 magnitude earthquake struck southern Mexico late Thursday and was felt as far away as Mexico City, the US Geological Survey said.
It hit offshore 120 kilometers (75 miles) southwest of the town of Tres Picos in the state of Chiapas and sparked warnings of tsunami waves across Central America.
There were no immediate reports of fatalities, but quakes of this size have caused massive destruction in the past.
