Minor Earthquake Shakes San Francisco Bay Area

Why this matters: Even minor earthquakes serve as a reminder of the region's seismic activity and the importance of preparedness. Residents should be aware of the possibility of aftershocks and review safety measures.

The earthquake, while minor, highlights the ongoing seismic activity in the San Francisco Bay Area. The USGS is monitoring the situation and may update the shake-severity map as more data becomes available. Aftershocks are a common occurrence following earthquakes and can pose a risk to already weakened structures. Residents should be prepared for potential aftershocks and know what to do in the event of another earthquake.

Understanding the Modified Mercalli Intensity scale helps to interpret the severity of the shaking. A shake intensity of 3 is defined as "weak," but the earthquake may be felt outside the areas shown on the map. Maps showing aftershocks within 100 miles and seven days of the initial quake are also available from the USGS.

Drop, cover, and hold on. Protect your head and neck.

An aftershock is a smaller earthquake that follows a larger one in the same general area.

Aftershocks can occur days, weeks, or even years after the initial earthquake.
