Recent Earthquake Activity
Over the past week, the region has experienced six tremors measuring 2.5 or greater. The most significant event was a 3.8 magnitude quake near Idyllwild on November 27. Below are the notable earthquakes reported:
- 3.8 magnitude southwest of Idyllwild on Nov. 27
- 3.5 magnitude southwest of Idyllwild on Nov. 27
- 3.0 magnitude southwest of Idyllwild on Nov. 28
- 2.6 magnitude south of Highland on Nov. 23

Understanding Earthquake Magnitude
Magnitude quantifies the energy released during an earthquake. The U.S. Geological Survey notes that the modern scale replaced the older Richter scale. Generally, earthquakes measuring between 2.5 and 5.4 are felt but seldom cause significant damage. In contrast, quakes below 2.5 are usually unnoticed by most individuals.
Earthquake Statistics
- 500,000 detectable earthquakes occur worldwide each year.
- Approximately 100,000 can be felt, with about 100 resulting in damage.
Safety Tips During an Earthquake
To ensure safety during an earthquake, follow the recommendations below:
- If in a vehicle: Pull over, stop, and set the parking brake.
- If in bed: Turn face-down and protect your head with a pillow.
- If outdoors: Stay clear of buildings; do not enter them.
- If indoors: Remain there and avoid moving outside. Steer clear of doorways.
According to experts, the best practice is to “Drop, Cover, and Hold On.” Find a sturdy surface, drop to your hands and knees, and hold on until the shaking subsides. If you use a mobility aid, ensure it’s secure and stay seated during the quake.
Post-earthquake hazards may include structural damage, gas leaks, and fallen power lines. Aftershocks are also a common occurrence, so be prepared to repeat safety measures if they happen.
