This tremor followed a more powerful 7.3 magnitude earthquake off the southern coast of Mexico, which led to a tsunami warning for several Pacific regions.
Authorities in both Mexico and Guatemala confirmed no deaths or significant damage from the strong quake, which was also felt in El Salvador. Mexico’s navy indicated there was “no serious impact” but advised residents to avoid beaches as a safety measure.
Initially, the US Tsunami Warning System alerted about potentially dangerous tsunami waves along the coasts of Mexico and Guatemala. Small wave heights of up to 0.3 meters above tide levels were later recorded in Puerto Madero and Chiapas before the warning was lifted.
The earthquake occurred near the fishing community of Puerto Madero at a depth of 15.2 km, according to the US Geological Survey (USGS). Multiple aftershocks, with magnitudes between 4.7 and 6.0, were reported.
Officials in the Mexican states of Oaxaca and Chiapas noted that the quake was felt moderately but resulted in no major damage. In Guatemala and El Salvador, the tremor caused evacuations as buildings swayed, although no injuries were recorded.
Guatemala’s President Bernardo Arévalo stated that emergency response teams were sent out following a separate 5.6 magnitude quake near Quetzaltenango, and confirmed that there were no reported fatalities.
The US National Oceanic and Atmospheric Administration (NOAA) also predicted minor tsunami waves under 0.3 meters along parts of the Pacific coast, impacting El Salvador, Colombia, Costa Rica, Ecuador, Nicaragua, Panama, Peru, and Honduras.
Authorities later announced that the tsunami threat had subsided but urged coastal residents to remain vigilant.
