A magnitude 5.5 earthquake struck southern Mexico’s Oaxaca state on Friday evening, according to Mexican authorities and the United States Geological Survey (USGS).
The quake, which occurred near the town of San Miguel Achiutla at a depth of 64 kilometers (40 miles), prompted Mexico City’s seismic alarm system to activate, sending residents briefly into the streets.
Mexican President Claudia Sheinbaum confirmed on X that no damage had been reported, while Oaxaca’s governor stated that emergency protocols had been activated in response to the tremor.
Seismic Alarm System Activated in Mexico City
The earthquake triggered Mexico City’s seismic alarm system, designed to provide early warnings of tremors. The alarms prompted residents to evacuate buildings and gather in open spaces as a precaution. While the quake was felt in the capital, no significant damage or injuries were reported.
Mexico City, located approximately 300 kilometers (186 miles) from the epicenter, is no stranger to earthquakes due to its location in a seismically active region. The city’s alarm system has been credited with saving lives by providing critical seconds for residents to seek safety.
Oaxaca’s Emergency Response
Oaxaca, one of Mexico’s most seismically active states, has well-established emergency protocols for responding to earthquakes. Governor Salomón Jara Cruz confirmed that these protocols were activated following the tremor, ensuring that local authorities were prepared to address any potential impacts.
The region’s history of seismic activity has led to the development of robust infrastructure and response systems, minimizing the risk of damage and casualties during moderate earthquakes like this one.
USGS Details on the Earthquake
According to the USGS, the earthquake’s epicenter was located near San Miguel Achiutla, a small town in Oaxaca. The quake’s depth of 64 kilometers (40 miles) classified it as an intermediate-depth earthquake, which typically causes less surface damage compared to shallow quakes.
The USGS also noted that earthquakes of this magnitude are relatively common in southern Mexico, where tectonic plate interactions frequently generate seismic activity.
