A powerful magnitude 7.3 earthquake struck off the coast of Mexico's southernmost state of Chiapas on Friday, shaking buildings as far away as Guatemala and El Salvador, according to multiple reports. Authorities reported no immediate casualties or major damage, though the tremor triggered a tsunami warning for parts of the Pacific.

The quake struck at a depth of 15.2 kilometers (9.4 miles), according to the US Geological Survey, after revising its earlier assessment of a magnitude 7.4 quake at a shallower depth of 10 kilometers.

Coverage Comparison

The earthquake was reported consistently across international media, with each outlet noting the magnitude, location, and the absence of immediate reports of casualties or major damage. The BBC highlighted the response from Mexican and Guatemalan presidents, while France 24 included personal accounts from residents in Guatemala City. The South China Morning Post emphasized the tsunami warning and the potential wave heights.

All three outlets described the earthquake as a natural disaster and focused on its impact across the region, with no significant variation in the core facts presented.

Key Claims

According to multiple reports, the earthquake struck near the coast of Mexico's Chiapas state at 08:49 local time (14:49 GMT) on Friday. The epicenter was located in the sea, 58 kilometers (36 miles) from the small coastal town of Puerto Madero.

The US Tsunami Warning System issued a warning for hazardous tsunami waves along coasts within 300 kilometers (186 miles) of the epicenter. For some coasts in Mexico and Guatemala, waves could reach between 0.3 meters (one foot) and one meter (three feet) above tide level, as reported by the South China Morning Post and France 24.

Mexico's navy secretary, Admiral Raymundo Morales, said during a government press conference that water levels were not expected to rise more than half a meter, but advised people to stay away from beaches. "There is no problem, no serious maritime impact," Morales said. "We only expect some beaches to see a rise in water level of up to half a meter due to the tsunami effect from the earthquake."

The US National Oceanic and Atmospheric Administration forecast waves of less than 0.3 meters above tide level along the coasts of El Salvador, Colombia, Costa Rica, Ecuador, Nicaragua, Panama, Peru, and Honduras, based on a single report.

A series of aftershocks with magnitudes between 4.7 and 6 were recorded, according to the BBC and France 24. Guatemala's President Bernardo Arévalo said the country's emergency management agency was deployed in response to a magnitude 5.6 earthquake with its epicenter in Quetzaltenango. No fatalities had been recorded so far, he added.

In Guatemala City, the earthquake shook buildings and prompted some residents to dash from their homes onto the street, as reported by France 24, citing a Reuters witness. Local media showed footage of staff evacuating a government building as security protocols were activated. Alexander Valdez, a 29-year-old accountant, told Reuters: "I got really scared and it reminded me of the recent earthquake in Venezuela. So I ran out and went down the stairs because I live on the eighth floor. The shaking wouldn't stop."

The tsunami warning was later lifted, with the US Tsunami Warning System advising people in affected areas to "remain observant and exercise normal caution near the sea," as reported by the BBC. The center recorded waves of 0.3 meters above tide level in Puerto Madero and Chiapas, Mexico.

Governor Salomón Jara Cruz of the southern Mexican state of Oaxaca said the quake was felt with "moderate intensity" but no significant damage had been reported. Eduardo Ramírez, governor of Chiapas, also said there had been no serious impact, but added he had instructed his cabinet to suspend administrative activities and urged the private sector to do the same.

Mexican President Claudia Sheinbaum said emergency protocols were activated but that neither Chiapas nor the neighboring state of Tabasco reported issues, as reported by the BBC. Guatemalan President Bernardo Arévalo said there were no deaths.

What was claimed, and who backed it

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
