Overview

• At 12:00 local time, millions participated in the Second Simulacro Nacional, evacuating buildings in an orderly exercise held across all 32 states.
• A cell-broadcast test reached roughly 80 million phones with a distinct tone and on-screen message, joining radio, TV and 14,491 public loudspeakers.
• The national scenario simulated an M8.1 earthquake near Lázaro Cárdenas, while states also drilled hurricanes, tsunamis or urban fires based on local risk.
• Authorities emphasized the alert does not require internet or prepaid balance and can sound on silent if emergency alerts are enabled; some users did not receive it due to device settings or compatibility, with a 079 helpline available.
• President Claudia Sheinbaum led a Zócalo ceremony with the flag at half-mast for the 1985 and 2017 victims, and media and agencies reported staged incidents and evacuations without major real emergencies.
