Overview
- The Servicio Sismológico Nacional confirmed a magnitude 6.1 quake 116 kilometers southwest of Guasave on June 30, 2026, with a reported depth of about 5.0 kilometers.
- The shallow focus made the tremor widely felt in Guasave, Culiacán, Los Mochis and parts of Baja California Sur, and prompted evacuations of some multi‑story buildings.
- As of the latest reports authorities have not confirmed structural damage or injuries and state and national protection units are carrying out building inspections and monitoring for aftershocks.
- The Navy’s tsunami warning center assessed sea levels and ruled out a tsunami threat, while early seismological estimates that ranged lower were revised by the SSN as more data were processed.
- Mexico’s complex plate setting makes frequent quakes common, so officials say continued monitoring for replicas and targeted infrastructure checks remain the priority for public safety.
