The City of American Canyon is located in the seismically active San Francisco Bay region. The most notable active fault in our area is the West Napa Fault. The West Napa Fault was the epicenter of the 6.0 South Napa Quake on August 24, 2014.

Earthquakes are incredibly random and strike without warning. Whether you are sleeping, working, taking a walk or cooking dinner, take responsibility now to minimize your risks. It’s important that you are ready and able to take care of yourself and your family both during and after an earthquake.


There are five important steps you can take to help you prepare for the next big one.

  1. Secure your space by identifying hazards, strengthening your property, and securing moveable items.

  2. Plan to be safe by creating an emergency plan. Decide how you will communicate with your family, friends, and colleagues in an emergency.

  3. Practice DROP, COVER, and HOLD ON with members of your household and office co-workers.

  4. Create your emergency supply kit and store in a convenient location.

  5. Minimize financial hardship by storing important documents in your emergency supply kit. You may also want to consider earthquake insurance.


A major earthquake will cause violent ground shaking. This shaking may make it difficult to stand up or walk. At the first sign of movement, take cover and protect yourself from falling or flying objects.

To keep yourself and your loved ones safe, remember to DROP, COVER, and HOLD ON.

You may find yourself in a situation you don’t expect when an earthquake hits. Before you hit the floor, ensure that you are in a safe place away from heavy bookcases, cabinets, glass doors, windows, hanging objects, buildings, power lines, or trees.

Once you know you are safe, immediately, DROP to the floor. Take COVER under a sturdy desk or table. If one is not available, cover the back of your neck and head with your hands and arms. Then, HANG ON to something stable. Stay where you are until the shaking stops.

After the shaking stops, move carefully. There may be broken glass, fallen items, or unstable structures. Be aware that aftershocks are highly likely. Directly after an earthquake, you should:

  • Check yourself and others around you for injuries. Provide assistance to others if you have training.

  • Look around to identify dangerous conditions, such as structural damage, broken glass, gas leaks, or fires.

  • Turn off the gas only if you believe there is a leak. Be aware that it may take several days after an incident for PG&E to turn the gas back on.

  • If you are in a damaged building, go outside and quickly move away from the building.

  • Tune your radio to 99.3 KVYN (FM), 1440 KVON (AM), and local television stations for further information.
