7.3 Magnitude Earthquake Strikes Mexico Coast Near Guatemala
A magnitude 7.3 earthquake struck off the coast of Mexico's southern Chiapas state near Guatemala on July 17, 2026, triggering a tsunami warning for parts of Mexico and Guatemala but causing no immediate major damage. The Mexico earthquake prompted evacuations in Guatemala City as residents fled homes and buildings amid fears connected to recent events elsewhere.
Initial Quake and Magnitude Revision
The quake struck at a depth of 15.2 km according to the USGS, which revised its initial 7.4 magnitude assessment at 10 km depth. [1] The US Geological Survey recorded the event near the coast of Mexico's southernmost state of Chiapas. [5] This revision adjusted both the magnitude downward from 7.4 and the depth from the initial shallow estimate of 10 km to the final reported depth of 15.2 km. [1] Authorities noted that the Mexico earthquake occurred on Friday and produced shaking felt across borders without immediate reports of structural harm. [5] The precise location placed the epicentre off the southern coast, allowing the tremor to reach neighbouring regions while remaining centred in Mexican waters. [1]
Tsunami Warning Issued
Following the tremor, the U.S. Tsunami Warning System said that hazardous tsunami waves were possible along coasts located within 300 km of the epicentre. [1] The waves could reach levels between 0.3 metre and 1 metre above tide level for some coasts in Mexico and Guatemala. [5] Mexico's secretary of the Navy, Raymundo Morales, said water levels were not expected to rise more than half a metre, but nevertheless advised people to stay away from beaches for now. [1] "There is no problem, no serious maritime impact," Morales said during a regular government press conference. [5] "We only expect some beaches to see a rise in water level of up to half a metre due to the tsunami effect from the earthquake." [1] The Mexico earthquake therefore led to a measured response that balanced the alert with reassurances about limited effects. [5]

Aftershocks Recorded
A series of aftershocks, including some with magnitudes between 5 and 6, were also felt in Mexico, Guatemala and El Salvador. [1] USGS recorded multiple aftershocks including a M5.0 at 59 km SSW of Puerto Madero, a M5.1 at 72 km SW of Puerto Madero, and a M5.1 at 78 km WSW of Puerto Madero. [2] The M5.0 event occurred at a depth of 35.1 km. [2] The two M5.1 events each registered at a depth of 10.0 km. [3] These aftershocks contributed to ongoing shaking reported across the three countries in the hours after the main Mexico earthquake. [5] Local observations confirmed that the sequence included events in the 5 to 6 magnitude range that sustained attention in the affected zones. [1]
Regional Impact in Guatemala
In Guatemala City, the earthquake shook buildings and prompted some residents to dash from their homes onto the street, according to a Reuters witness. [1] Local media in Guatemala showed footage of staff evacuating a government building as security protocols were activated. [5] "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," Alexander Valdez, a 29-year-old accountant, told Reuters in Guatemala City. [1] Adolfo Zacarias, a 43-year-old customer service worker who lives on the third floor of his building, said he sought shelter under a structural column as the shaking began. [5] "I think the memories of what recently happened in Venezuela came back to us and that scared us a lot," Zacarias said. [1] The Mexico earthquake therefore intersected with existing regional sensitivities, leading to visible public reactions in the capital. [5]
No Immediate Damage Reported
Authorities reported no immediate damage. [1] Mexico's Navy Secretary stated rises would not exceed half a metre and there was no serious maritime impact. [5] Officials across the region confirmed the absence of major effects on infrastructure or coastal activities following the Mexico earthquake. [1] The combination of the main shock and subsequent aftershocks produced no reports of serious harm despite the widespread shaking. [5] Government statements emphasised that the event remained contained in its physical consequences. [1]
What to watch next: Further aftershocks in the 5 to 6 magnitude range may continue to be felt in Mexico, Guatemala and El Salvador.
