Three earthquakes struck off the coast of Sinaloa on Wednesday, July 2, rattling residents across multiple municipalities in Baja California Sur. The strongest quake registered a 6.1 magnitude at 12:45 p.m. local time. No injuries or structural damage were confirmed in BCS.
The series of earthquakes originated off the Sinaloa coastline in the Gulf of California. A third tremor, measuring 4.8 magnitude, was detected just 131 kilometers (about 81 miles) from La Paz at a shallow depth of 9.9 kilometers. That quake was felt across several communities in both Sinaloa and BCS.
Civil Protection Clears Buildings After Inspections
The Sinaloa State Civil Protection Institute reported no structural damage from any of the three events, though inspections were still ongoing at the time of the initial report. In BCS, authorities evacuated some buildings as a precaution and later cleared them for re-entry after completing inspections.
No injuries were reported on either side of the Gulf. Authorities in both states continued monitoring the situation throughout the afternoon.
BCS Sits in an Active Seismic Zone
The earthquakes are consistent with the region’s well-documented seismic activity. According to earthquake monitoring data, BCS experiences an average of 645 earthquakes of magnitude 4.0 or higher every decade, roughly one notable quake every six days. The state has recorded at least nine earthquakes above magnitude 7.0 since 1900.
The strongest earthquake ever recorded near BCS was a 7.3 magnitude event on April 10, 1906. Its epicenter was located 62 kilometers north-northwest of La Paz, under the Gulf of California at a depth of 15 kilometers.
What to Know About Earthquake Preparedness
A 6.1 magnitude earthquake is classified as “strong” and can cause damage to poorly constructed buildings, though well-engineered structures typically withstand it without major issues. The shallow depth of Wednesday’s smaller 4.8 quake, at just 9.9 kilometers, made it more perceptible at the surface despite its lower magnitude.
Residents in La Paz, Los Cabos, and other BCS communities should know the location of their nearest emergency assembly point. In most Mexican cities, these are marked with green signs reading “Punto de Reunión” in public plazas and parks.
