Tsunami risks on coastlines is something possible due to their location. Though these disasters occur in very specific occasions, one can never rule out the possibility that it could happen. This is why the California Geological Survey updated its tsunami hazard maps for seven counties.

One of these counties is San Diego. The update explains evacuation routes so that the residents of these areas know where to go in case water spreads and know which are the safest locations in case a tsunami occurs.

This information was also updated for the Napa, Santa Cruz, Solano, Sonoma, Ventura, and Marin counties. It should be noted that this map, along with the tsunami risk assessment, is based on the flood tsunami maps of 2009. They are also the result of a high-resolution probability model with a 975-year return period.

If you go to the California Geological Survey webpage, one can specify whether the area one lives in, works at, or is visiting is colored yellow. If you are in one of these areas after a long earthquake or if you receive an evacuation notification, you should walk to one of the green areas of the map.

You can also use this map to outline an evacuation route to a safe area. You can also practice taking this route so that both residents and your family are prepared for these unexpected events. If you wish to know more about these safe county areas, click here.
