Overview
- The alert will be transmitted through roughly 13,992 C5 loudspeaker posts in Mexico City, as well as via dedicated receivers, radio, television and cell broadcast messaging.
- CDMX will implement its Emergency Plan with an initial damage scan using C5 cameras and Condores helicopter overflights, the Emergency Committee at C5, borough protection councils and deployment down to 1,017 territorial quadrants.
- The State of Mexico will activate its own alert and protocols, install its C5 emergency committee, and deploy Relámpagos helicopters, with special focus on the state’s eastern zone under the drill’s impact assumptions.
- The drill hypothesis models a magnitude 7.2 quake 11 km south of Pinotepa Nacional, Oaxaca, at 12 km depth, with strong shaking expected on lacustrine and transition soils and moderate effects on hill zones in the Valley of Mexico.
- Officials set a three‑drill schedule for 2026 (Feb. 18 metropolitan, May 6 with federal coordination, Sept. 19), while recent magnitude 4.0–4.6 events in Mexico and Peru yielded no major damage and did not trigger the Mexico City alert.
