A powerful 7.3 magnitude earthquake struck off the coast of southern Mexico on Friday, triggering a tsunami warning for parts of the Pacific.

No fatalities or significant damage have been reported in Mexico or Guatemala from the earthquake, which was also felt in El Salvador.

Mexico’s Navy Secretary, Admiral Raymundo Morales, said at a news conference that “there was no serious impact” but that people were advised to stay away from the beaches.

The US Tsunami Warning System had warned of possible ““Dangerous tsunami waves” along the nearby coasts of Mexico and Guatemala. It later recorded waves of 0.3 m (1.1 ft) above tide level in Puerto Madero and Chiapas in Mexico.

Several hours after the initial warning was issued, the center said the threat had passed, but advised people in affected areas to “remain vigilant and exercise normal precautions near the sea.”

The earthquake, which occurred near the fishing town of Puerto Madero in Mexico at 8:49 a.m. local time (2:49 p.m. GMT) on Friday, had a depth of 15.2 kilometers (9 miles), according to the United States Geological Survey (USGS).

The governor of the Mexican state of Oaxaca, Salomón Jara Cruz, said the earthquake was felt with “moderate intensity” but no significant damage was reported.

Eduardo Ramírez, governor of the state of Chiapas closest to the epicenter, also said there had been no serious impact, but added that he had ordered his cabinet to suspend administrative activities and urged the private sector to do the same.

In Guatemala and El Salvador, the tremor shook buildings, prompting evacuations and causing some people to flee their homes, the Reuters news agency reported.

A series of aftershocks have been recorded, with magnitudes between 4.7 and 6.
