Earthquakes

Get alerts

My Shake is a free smartphone app that gives you audio and visual warnings about shaking. It will warn you when shaking is at a magnitude 4.5 or higher. When it detects a significant magnitude shake, the system issues a ShakeAlert® Message. This gives you a warning before the shaking starts. The app is also available in Spanish.
Download the free app from the Apple App Store or Google Play.

Build a Stay Box 

We call it a “box,” but it doesn’t matter what you use, the goal is to keep your supplies together in one place, like a closet or corner of the garage. A Stay Box should have enough essentials for you and your family to stay safe at home for 3–5 days. This is especially important during situations like a shelter-in-place after an earthquake.

Make a Plan 

Know how you’ll find and stay in touch with your family during an earthquake. It won’t take long to make a plan.  

Protect your home. Secure items in your home that could injure you during an earthquake. Try tackling one item each weekend until everything is done:

• Anchor heavy furniture like bookcases and TVs.
• Secure wall hangings.
• Store heavy and breakable objects on lower shelves.

Start with free or low-cost fixes and ask friends for help. Sharing these steps can inspire your circle to get prepared too. 

Consider obtaining earthquake insurance. A standard homeowner’s insurance policy does not cover earthquake damage.

1. Drop, cover and hold on. Drop down and get under a strong table. If you are not near a table, drop against an interior wall. Cover your head and neck with your arms. Stay away from windows.
2. Stay put. Whether you’re in a car, bed, or public place, stay put and wait until the shaking stops. If you’re outside, stay away from wires or falling objects. But if you’re near the coast during an earthquake, immediately go to high ground, because tsunamis can follow.
3. Stay calm. Keeping your wits about you will ensure that you make safe choices for yourself and those around you.

Accessibility Specific Tips 

• If you are in a recliner or bed: Cover your head and neck with your arms or a pillow until the shaking stops.
• If you use a cane: Drop, cover, and hold on. Or sit on a chair or bed and cover your head and neck with both hands. Keep your cane near you so you can use it when the shaking stops.
• If you use a walker or wheelchair: Lock your wheels (if applicable). If using a walker carefully get as low as possible. Bend over and cover your head and neck with your arms, a book, or a pillow.

• Check your surroundings. Check for damage, and look for anyone who is injured and in need of attention. If you are in a Neighborhood Response Group, check in with your Block Captain.
• Leave a trail. If you leave home, leave a sign telling friends and family your new location. Text your emergency contact or update your social media pages to say you’re okay.
• Stay tuned. Check the Marin County Public Emergency Portal for local up-to-date information. Listen to the radio for important information and instructions. Aftershocks, which often follow large earthquakes, can cause damage too.
