Overview
- At 11:00 a.m. on Feb. 18, a regional drill in Mexico City and the State of Mexico will simulate a magnitude 7.2 earthquake near Pinotepa Nacional, Oaxaca.
- Roughly 13,900 public loudspeakers will sound and compatible phones will receive alerts, with authorities urging participants to follow evacuation protocols.
- The exercise is limited to CDMX and Edomex and is designed to measure reaction times, coordination, and the performance of the seismic‑alert network.
- Mexico City has enabled an online platform to register buildings and download a Family Protection Plan to document participation and improve preparedness.
- Officials reported normal operation of alerts during three early‑2026 quakes and confirmed national drills for May 6 and Sept. 19, while developing changes to reduce cellphone alert volume and modify message text.
