On February 28, 2025, Mexico experienced notable seismic activity, reminding citizens of its geographical vulnerability to earthquakes. The Servicio Sismológico Nacional (SSN) reported two earthquakes occurring within minutes of each other, one at 1:33 PM near Coahuila and another at 1:39 PM, with its epicenter located 15 kilometers south of Iguala, Guerrero, registering at 5.2 on the Richter scale.
The earthquake near Iguala triggered concerns but fortunately did not result in any casualties or significant damage. Citizens experienced the tremors differently; some felt the seismic jolts strongly, whereas others barely noticed the disturbances. Social media platforms quickly filled with memes and reactions, leveraging humor to cope with the surprise of the quakes.
A common inquiry during such events focuses on the alert system for seismic activity. Why did the alert not sound for this earthquake? According to experts, the seismic alert system is only triggered by quakes exceeding 5.6 to 6.0 on the Richter scale. Meanwhile, the sensors monitoring seismic activity do not extend to the capital, primarily active along the Pacific coastline.
Despite not engaging the alert system, the earthquake was felt across various locations, including the capital. Within the city, the tremor prompted some residents to evacuate buildings due to fear of aftershocks. Myriam Urzúa, head of the Secretaría de Gestión Integral de Riesgos y Protección Civil for Mexico City, noted during interviews, "The situation has been assessed, and we have not recorded significant damage. We will continue monitoring potential impacts."
The Mexican seismic situation is persistent and rooted deeply within its geography—situated along the Pacific Ring of Fire, where numerous tectonic plates converge. This reality means the country frequently experiences earthquakes and tremors.
Understanding the patterns of seismic activity is key to enhancing safety and preparedness. The Centro Nacional de Prevención de Desastres (CENAPRED) has continuously provided guidance not only on immediate responses during earthquakes, like seeking shelter under sturdy furniture but also on preparations for potential future incidents.
The recent earthquakes serve as vivid reminders of Mexico's seismic phenomenon. A previous earthquake occurred just six minutes before the significant one near Guerrero—it measured 5.5 and originated from Texas, USA, about 347 kilometers north of Ciudad Acuña, Coahuila.
Residents were reminded of the historical earthquakes of 1985 and 2017, which devastated parts of the country, leading to deaths and destruction. These past tragedies are fresh memories for many, causing anxiety during any earthquake event, regardless of magnitude.
Historically, Mexico has experienced significant earthquakes, including the 1787 quake, which, noted for its 8.6 magnitude, was accompanied by tsunamis. Experts caution the occurrence of substantial earthquakes remains feasible due to energy buildup on various geological fault lines, particularly along the Guerrero Gap.
Even with the absence of substantial damage following today’s events, it is advantageous to promote continuous learning and preparedness among residents. Practical steps include establishing emergency plans, holding evacuation drills, and creating emergency kits, as advised by authorities.
It’s noteworthy how the Mexican government continues to invest efforts to educate citizens about seismic risks and responses. The need for active engagement and training becomes imperative, especially considering potential future tremors.
Pertinently, during and after seismic events, CENAPRED suggests individuals maintain composure, avoid hazardous areas, and utilize communication responsibly to ease the burden on emergency services.
Photos and infographics detailing areas of high seismic incidents, common practices before, during, and after tremors can be found on designated government websites, serving as valuable resources for public education.
Given the frequency of these disturbances, establishing culture-based preparedness can be pivotal for the nation moving forward. New standards of awareness and readiness can shape the actions of citizens and the response of the government as they work to increase resilience against natural disasters.
