- The seismic alert network, including the nationwide cell-broadcast presidential warning, sounded across multiple states and prompted orderly evacuations and safety protocols.
- President Claudia Sheinbaum’s morning briefing was briefly halted as Palacio Nacional was evacuated; overflights and ground checks were activated across the capital.
- Authorities cited no major structural damage or casualties in early assessments, though power and phone service interruptions were reported near the coast, including parts of Acapulco.
- Aftershocks were noted and monitoring continues across central and southern states; separately, a shallow M4.5 quake off Nasca, Peru, on January 1 caused no reported damage.
