Thanks to @uccawx I learned San Mateo County in California, where I live, has a Tsunami Hazard Area Dashboard. it’s super easy to use, too.

Bad news: I’m in a tsunami hazard area. (But I knew that from the last time I looked at such maps.)

Good news: I can drive a very short distance in one of two directions and get out of the hazard area — I don’t need to go as far as I went when we had a tsunami alert a while back. That’s good, because traffic was hideous when we got that alert.

Welcome to the San Mateo County Tsunami Hazard Area Dashboard!

To see if you are in an unsafe area during a tsunami, click the search box at the top of the page and type in an address or choose "Use current location". The pop-up box "Are You In a Hazard Area" will say Yes or No. If you are in the Yellow Zone during a tsunami warning, relocate to the Green Zone.

Overview

The Tsunami Hazard Map was created by the San Mateo County Department of Emergency Management to help identify areas that could potentially be impacted by a tsunami. This map is designed for use by residents within the local jurisdiction and for emergency planning purposes. While the map outlines the worst case scenario (yellow), it does not provide information about the probability of such events occurring nor is it intended to serve as a legal document. #tsunami #SanMateoCounty #CA
