Mexico carried out its annual nationwide earthquake drill this week, using the exercise to test a phone-based alert system alongside the country’s traditional seismic alarm network. Around midday, sirens sounded in Mexico City as part of the coordinated drill, prompting residents to practice evacuation procedures.
The exercise coincides with a somber date on the Mexican calendar: it commemorates the devastating earthquakes of September 19, 1985, and September 19, 2017, both of which struck on the same day decades apart and killed thousands of people across the country. Millions of Mexicans take part in the yearly drill as a way of honoring the victims of those disasters while reinforcing public preparedness.
This year’s drill placed special emphasis on evaluating how well mobile phone alerts complement the existing seismic alarm system, which relies on speakers installed throughout earthquake-prone areas like the capital. Authorities are exploring whether smartphone notifications can reach residents more quickly or in areas where the physical alarm network has gaps, potentially strengthening the country’s early-warning capabilities ahead of future seismic events.
Mexico sits atop several active fault lines, making earthquake preparedness a critical part of civil protection policy. Want more details on how the drill unfolded? Check out the original report.
