In the early hours of Tuesday, a small but noticeable 2.6 magnitude earthquake rattled parts of San Ramon, California, reminding residents once again why earthquake preparedness matters. According to the U.S. Geological Survey (USGS), the quake struck right around 12:08 a.m. on November 18, catching many late-night Californians off guard.
Where the Earthquake Hit
The tremor’s epicenter was located about 2 miles southeast of San Ramon, shaking at a depth of roughly 5 miles. While a 2.6 magnitude quake is generally considered light, many people still reported feeling a quick jolt or brief shaking.
As of this morning, over 30 residents have already submitted “Did You Feel It?” reports on the USGS website—so if you felt anything unusual last night, you can still share your experience with the agency.
Not the First Quake This Week
This wasn’t an isolated event. Just five days earlier, the Bay Area felt a stronger 3.5 magnitude earthquake near Vallejo, showing a bit of elevated seismic activity in Northern California this week.

What These Magnitudes Mean
If you’re wondering how strong a 2.6 earthquake is, here’s a quick breakdown:
- Below 2.5: Usually not felt
- 2.5–5.4: Often felt, rarely causes damage
- 5.5+: Can cause structural damage depending on the area
California is one of the most earthquake-prone states in the country, along with Alaska, Hawaii, Washington, Oregon, and Puerto Rico. Globally, more than 500,000 detectable earthquakes happen every year—about 100,000 are felt, and around 100 cause damage.
What To Do If an Earthquake Strikes
Safety experts continue to emphasize one golden rule:
Drop, Cover, and Hold On.
Here’s what to do depending on where you are:
- Inside: Stay there. Move away from windows and unstable furniture.
- In bed: Stay down, face the mattress, and cover your head with a pillow.
- Outside: Move away from buildings, streetlights, and power lines.
- In a car: Pull over, stop, and set your parking brake.
After any quake, be prepared for aftershocks, check for hazards like gas leaks, and stay alert.
Stay Safe, California
Earthquakes like this are a reminder to keep your emergency kits stocked, your phones charged, and your plans ready. Even small tremors can be wake-up calls.
If you felt last night’s earthquake in California, take a moment to report it—it helps scientists understand how these quakes travel and who they affect.
Stay safe, stay prepared, and stay informed.
