4.1 Magnitude Earthquake Shakes Central California Tuesday Morning

San Luis Obispo, California — A 4.1-magnitude earthquake struck Central California on Tuesday morning, rattling residents and causing many to report shaking. According to the United States Geological Survey (USGS), the quake occurred at 9:54 a.m. Pacific Time, about 8 miles southwest of Paso Robles and 4.6 miles west of Templeton.

The earthquake’s depth was estimated at around 3 miles, and it was felt by over 1,000 residents in the area. Reports described moderate shaking near the epicenter, while lighter tremors reached as far south as Santa Maria and Lompoc.

Initially, the USGS reported the earthquake’s magnitude as 4.4 before revising it to 4.1 following further analysis. Seismologists note that additional data may still lead to changes in the reported magnitude or severity map for the region.

Following the main quake, at least 10 aftershocks have been detected, the strongest registering at magnitude 2.3. Aftershocks can occur days, weeks, or even years after the initial event and may further impact already affected areas.

This region is known for its seismic activity due to several smaller faults that connect to the San Andreas fault system, which is responsible for the frequent small to moderate earthquakes experienced in Central California.

Local residents are encouraged to be prepared for future seismic events by reviewing disaster preparedness resources.
