Every year on September 19, Mexico conducts a nationwide earthquake drill to commemorate the devastating quakes of 1985 and 2017—both of which struck on the same date and left deep scars on the nation’s memory. The drill serves as a vital exercise in preparedness, aiming to strengthen public awareness and emergency response capabilities. In 2025, the drill was held at 11:00 a.m. local time, simulating a hypothetical 7.5 magnitude earthquake with an epicenter in Guerrero. Over 14,000 loudspeakers across Mexico City activated the Seismic Alert System (SASMEX), which celebrates its 30th anniversary this year. By honoring the lives lost in past disasters and reinforcing safety measures, the September 19 drill remains a cornerstone of national solidarity and proactive risk management.
