(CNN)-- A powerful earthquake struck southern Mexico on Friday, with tremors felt in both Guatemala and El Salvador, as the US Geological Survey initially estimated its magnitude at 7.3 on the Richter scale.

The agency said the epicenter was located 48 kilometers southwest of the town of Aquiles Serdán in the coastal state of Chiapas, Mexico.

The quake appeared to cause moderate to strong shaking along the coast.

The Pacific Tsunami Warning Center warned of possible hazardous tsunami waves within 300 kilometers of the epicenter.

It added that tsunami waves could reach up to 1 meter above tide level along the coasts of Guatemala and Mexico.

For his part, Mexican Navy Secretary Raymundo Pedro Morales Ángeles said there were 'no issues' in the country following the earthquake.

He added, at the conclusion of President Claudia Sheinbaum's daily morning press conference: 'There is no serious damage. Regarding maritime conditions, sea levels are expected to rise on some beaches by up to half a meter due to the quake. We advise citizens to stay away from the beaches for now.'

Meanwhile, the governor of the Mexican state of Oaxaca, Salomón Jara Cruz, said the earthquake was felt 'moderately strong' in the state capital, adding that 'no major damage' has been reported so far.

Guatemala President Bernardo Arévalo said no deaths have been reported so far, noting that emergency response plans are being activated.

Meanwhile, the fire department in El Salvador announced that it has not yet detected any damage within the country.
