Tsunamis may be rare, but every coastline in the world—including California’s—is vulnerable. While we can’t prevent a tsunami, we can significantly reduce its impact through preparedness, timely warnings, and effective response.

From March 22 to 30, Cal OES, the California Geological Survey, and the National Weather Service will work together through the California Tsunami Program to support local coastal communities with evacuation exercises, community drills (tsunami walks), preparedness fairs, and educational presentations.

Know How to Stay Safe

A tsunami can strike with little warning. The best way to protect yourself is to be prepared:
✅ Protect yourself during local earthquakes
✅ Move to high ground or go inland immediately
✅ Stay there until officials declare it safe

Know Your Tsunami Zone

The purpose of TsunamiZone.org is to help individuals and organizations understand their tsunami zones, recognize the warning signs of an incoming tsunami, and respond effectively. Throughout the year, you are encouraged to participate in tsunami education activities and drills, and to register your participation on this website.

Stay Informed

Being prepared isn't just about tsunamis—wildfire risks also require constant vigilance. Southern Marin residents should monitor multiple sources for emergency alerts, including:

• Alert Marin
• Nixle
• Local TV & radio
• Social media (Facebook, Twitter, Nextdoor)

Trust your senses—look, listen, and smell for signs of danger.
