floriparesort.com – 18 July 2026 | A powerful 7.3 quake hits Mexican coast, striking off the southern coast of Mexico early Friday morning, rattling the region and triggering immediate infrastructure reviews by emergency officials. The U.S. Geological Survey (USGS) said the quake struck near the Pacific coast of Chiapas state. The 7.3 quake hits Mexican coast at a shallow depth of roughly 9 miles, a factor that typically amplifies the intensity of shaking and expands the area where it can be felt.
The main tremor was part of a broader sequence of seismic activity in the area. Weaker earthquakes rattled the region shortly before and after the main event, including a magnitude 4.7 quake near Aquiles Serdán, alongside tremors of magnitude 5.1, 5.3, and 6.0 near Puerto Madero. As the 7.3 quake hits Mexican coast, analysts are still reviewing the PAGER impact assessment results that report the estimated damage. But given the size and location of the earthquake, damage is possible, according to USGS spokesperson Steven Sobieszczyk.
After the quake, a tsunami threat was issued for the coastlines of Mexico and Guatemala. Preliminary data from the USGS placed the epicenter approximately 30 miles southwest of Aquiles Serdán, a coastal community in Chiapas, and near the port town of Puerto Madero near the Guatemala border. The earthquake struck at 8:48 a.m. local time. A magnitude 7.0 or greater earthquake is classified as a major event capable of causing severe to catastrophic damage, particularly near the epicenter and in areas with vulnerable buildings.
As the 7.3 quake hits Mexican coast, recent USGS assessments note that earthquakes of this magnitude carry the potential for significant structural damage, fatalities, landslides, liquefaction, and widespread infrastructure disruptions. Historically, this part of Mexico is prone to large earthquakes, where the Cocos plate subducts beneath the North America plate at a rate of approximately 76 mm/yr. There have been at least eight magnitude 7 or greater quakes in this region since 2000, with the last closest one being a M7.4 in June 2020. The most recent, largest quake was a M8.2 earthquake in September 2017.

There were no immediate reports of deaths or major damage in the minutes following the earthquake, but authorities were expected to evaluate infrastructure and monitor coastal areas for possible tsunami impacts. Videos shared on social media showed strong shaking when the earthquake occurred. The 7.3 quake hits Mexican coast, and as a result, a tsunami was not expected in the U.S. because of the quake, NWS Tsunami Alerts said.
In conclusion, the 7.3 quake hits Mexican coast, causing widespread panic and triggering immediate infrastructure reviews by emergency officials. As the region begins to assess the damage and respond to the disaster, it is clear that the full extent of the earthquake’s impact will not be known for some time. However, one thing is certain: the people of Mexico and Guatemala will come together to support each other and rebuild in the aftermath of this devastating event. The 7.3 quake hits Mexican coast will be remembered as a significant event in the region’s history, and it will serve as a reminder of the importance of disaster preparedness and response.
