A 4.3 magnitude earthquake occurred off the coast of Baja California Sur on the morning of Friday, October 30, according to the National Seismological Service (SSN). The seismic event, which took place at 07:16 Central Time, was centered in the Pacific Ocean approximately 238 kilometers southeast of San José del Cabo at a depth of 10 kilometers. The epicenter was pinpointed by authorities at coordinates 21.61 north latitude and -108.00 west longitude.
Impact of the tremor near Los Cabos
Because of the significant distance between the epicenter and the mainland, the movement was largely unnoticed by residents in the Los Cabos region. Municipal and state authorities have reported no damage or injuries resulting from the tremor. While the earthquake reached a magnitude of 4.3, its perception on land was mitigated by the depth of the event and its distance from populated urban centers, as noted by the SSN. The epicenter was located far from the municipality’s primary inhabited areas, ensuring that the event had no impact on local communities.
Geographic and technical data
While the SSN logged the event at 07:16 Central Time, local records indicated the tremor occurred at 06:16 local time. The seismic activity was recorded within the agency’s ongoing national monitoring program, which tracks tectonic shifts across the region.
Tectonic activity in the Baja California region
Baja California Sur is situated in a zone of frequent seismic activity driven by the interaction between the Pacific and North American tectonic plates. This geological environment regularly produces tremors, particularly within the Gulf of California and surrounding marine areas.

Frequently asked questions about the Baja California earthquake
Was this earthquake related to the San Andrés Fault? While the region experiences significant tectonic activity, officials clarified that this specific tremor did not occur directly on the San Andrés Fault.
Why did residents not feel the earthquake? The earthquake was not widely felt because the epicenter was located 238 kilometers offshore. The seismic event’s 10-kilometer depth and distance from the coast resulted in it remaining largely unnoticed by the population of Los Cabos, according to reports.
Are there any official reports of damage?
As of the latest update from the National Seismological Service and local authorities, there are no reports of property damage or injuries caused by the seismic activity.
