Mexico has scheduled its Second National Drill for September 19, 2026, at 12:00 PM central time. Coordinated by Civil Protection authorities, the exercise is designed to test evacuation routes, institutional communication, and emergency response protocols.

The drill will utilize five distinct seismic scenarios based on geophysical data. The primary simulation involves a 7.7 magnitude earthquake with an epicenter 15 kilometers southwest of Tehuacán, Puebla, at a depth of 67 kilometers, affecting regions including Mexico City, Puebla, Veracruz, and Jalisco. Other hypothetical scenarios include earthquakes in Quintana Roo, Mexicali, Allende, and Tonalá. The government also intends to test mass alert systems via mobile phones during the exercise.
