Millions of people enjoy California's coastline! Whether you live, work or visit, it is important to be aware that the coastal region is vulnerable to tsunamis. California's large offshore faults and steep underwater slopes can cause a local tsunami to arrive in minutes. Tsunamis can also travel across the ocean from distant earthquakes.
California tsunami inundation maps show where areas on land can become quickly flooded when there is a tsunami. Tsunamis produce strong, rapidly moving currents that can flow onto normally dry land. Tsunamis are also dangerous for people in the water and boats or ships near the coastline.
Inundation maps help guide people from dangerous areas to safe areas by showing where high, safe ground is located. These maps are useful to help plan a safe evacuation route. You can practice walking out of the tsunami zone to be better prepared for a real tsunami.
