After the tremor, recorded at 08:48 hours (16:48 hours in mainland Spain), the United States Tsunami Warning System issued a tsunami alert for the region due to the possibility of dangerous tsunami waves on the coasts located less than 300 km (186 miles) from the epicenter.

According to the USGS, the waves could exceed the usual high tide level by between 0.3 and 1 meter. The Mexican alert service indicated that the area most affected will be the coast of Chiapas and Oaxaca, states in southern Mexico, and recommends “keeping the population away from the beaches until the alert is canceled; strong currents are expected at the entrances of the ports.”

In Guatemala City, the earthquake shook buildings and caused some residents to run out of their homes into the street, according to a Reuters witness. Local media in Guatemala showed images of personnel evacuating a government building while security protocols were activated.

The country’s president, Bernardo Arévalo, made a “call to the population to remain calm and follow the recommendations” of the authorities although “so far there are no fatalities and we are monitoring the situation minute by minute.”

According to another Reuters witness, the tremor was also felt in El Salvador.

In the Mexican state of Oaxaca, Governor Salomón Jara reported on social media that the earthquake was felt with moderate intensity in the capital.

In an initial assessment, the Mexican Secretary of the Navy, Admiral Raymundo Pedro Morales Ángeles, estimated that for now there is no evidence of “serious damage” from the tremor, although he has recommended residents to take extreme precautions because a rise in coastal waters of about half a meter is expected but, otherwise, “there is no problem.”
