Understanding Tsunami Signage

Most emergency management agencies responsible for areas along the California coast went through a vigorous process to identify tsunami hazard zones and then placed signs in specific areas to delineate the perimeter of the inundation zone, evacuation routes and appropriate action to be taken by individuals when an earthquake occurs.

	If you see a Tsunami Hazard Zone sign, you are in an area that could, potentially, be inundated by a tsunami. Upon seeing this sign, identify possible locations to which you will travel when the water starts moving.
	The Tsunami Evacuation Route sign is used with arrows to direct individuals toward a safe area. When evacuating after an earthquake, follow the arrows until reaching an evacuation site. These signs can be found on state highways as well as local streets and roads.
	The signs indicating you are in a tsunami hazard zone and should go to high ground or inland in the event of an earthquake are generally located near the immediate coastline, in parking lots, at parks and beaches. When seeing this sign, be prepared by taking note of the location to which you will go after an earthquake. In most cases, safe, high ground is reachable by foot.
	The Entering/Leaving Tsunami Hazard Zone sign is used to delineate the boundary of defined inundation areas on State highways, local street and roads. You are considered safe, and out of the tsunami hazard zone, if moving inland away from the coast, from these signs.
	Signs designating an Evacuation Site may be used to direct road users (including pedestrians and bicyclists) to safe areas. Such a sign is further confirmation that you’ve reached safe, high ground.
