According to the US Geological Survey (USGS), the quake struck near the coastal town of Puerto Madero in Mexico's Chiapas state at a shallow depth of 10 kilometres, increasing the intensity of ground shaking in nearby areas.

Tsunami warning issued

Following the earthquake, the US Tsunami Warning System warned that hazardous tsunami waves were possible along coastlines within 300 kilometres of the epicentre.

Authorities continued to monitor coastal areas as a precaution, though there were no immediate reports of tsunami impacts.

Tremors felt across three countries

The earthquake was widely felt in neighbouring Guatemala, where buildings swayed in the capital, prompting residents to rush outdoors.

Local media showed government employees evacuating office buildings as emergency safety protocols were activated.

The tremor was also felt in neighbouring El Salvador, according to Reuters witnesses.

Despite the strong shaking, authorities in Mexico said there were no immediate reports of significant damage or casualties.

In Oaxaca, Governor Salomón Jara said the earthquake was felt with moderate intensity in the state capital but that initial assessments had not revealed any serious damage.

Emergency officials in Mexico and neighbouring countries continued to assess the situation as aftershocks remained possible.
