A powerful 7.3-magnitude earthquake struck off the southern coast of Mexico on Friday, July 17, triggering a tsunami alert for parts of the Pacific coastline and causing widespread panic across Mexico and neighbouring Central American countries.

According to the United States Geological Survey (USGS), the earthquake occurred about 48 kilometres off the coast of Aquiles Serdán at a depth of approximately 18 kilometres.

Mexico's National Seismological Service reported more than 30 aftershocks following the initial quake, with the strongest measuring magnitude 6.8.

In response, the United States National Oceanic and Atmospheric Administration (NOAA) issued a tsunami threat alert, prompting authorities to advise residents in coastal communities to stay away from beaches as a precaution.

The earthquake was strongly felt across the Mexican states of Chiapas and Oaxaca, as well as in neighbouring Guatemala and El Salvador.

As of the time of reporting, no deaths or serious injuries had been confirmed.

In Tuxtla Gutiérrez, the capital of Chiapas State, frightened residents rushed out of buildings as the tremor shook the city.

Mexican President Claudia Sheinbaum said she had been in contact with the governors of the affected states to monitor the situation, while Navy Secretary Raymundo Morales assured the public that there had been no significant damage.

"There are no serious effects," the government said as emergency officials continued to assess the impact of the earthquake.

In Guatemala City, authorities evacuated several buildings and suspended classes in communities near the Mexican border due to the strength of the tremor.

Although Mexico City is located more than 800 kilometres from the epicentre, residents reported feeling the earthquake, prompting precautionary evacuations from a number of high-rise buildings.

Mexico and much of Central America lie along active tectonic plate boundaries within the Pacific Ring of Fire, making the region one of the most seismically active areas in the world.
