A moderate seismic event registered a magnitude of 4.20 early this morning in the Gulf Of California. Global monitoring agencies confirmed the tremor occurred on February 4, 2026, at 11:33:40 UTC, affecting the central section of the active tectonic boundary.
Preliminary geophysical assessment places the hypocenter at a shallow depth of 10.0 kilometers. The calculated epicenter location was near 27.50 N latitude and -111.05 W longitude, positioning the event within a seismically dynamic region characterized by the spreading center between the Pacific and North American plates.
Ambient environmental conditions at the time of the event showed cool temperatures and dense cloud cover. Monitoring stations reported overcast clouds and an air temperature of 18.6°C.
Events of this magnitude are considered characteristic of the ongoing tectonic stresses within the Gulf’s extensive network of transform faults and rift zones.
