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

Today In Labor History March 27, 1964: The magnitude of 9.2 Good Friday earthquake struck Southcentral Alaska, killing 125 people and inflicting massive damage to the city of Anchorage. It was the most powerful earthquake recorded in North American history. 600 miles of fault fractured at once, moved up to 60 feet and released 500 years of pent-up stress. 200 miles away, in Kodiak, some areas were permanently raised 30 feet. Parts of Anchorage dropped by 8 feet. The quake generated tsunamis that wiped out many small Alaskan villages, and others that damaged Washington, Oregon, California, Hawaii and Japan. In Hawaii, a 12.5-foot tsunami hit Hilo, causing relatively minor damage. However, just 4 years prior, the great Chilean Quake of 1960 (9.5 magnitude) generated a tsunami that destroyed much of Hilo and killed 61 people. And on April 1, 1946, an 8.6 quake in Alaska caused Hawaii’s worst ever tsunami (some waves were over 50 feet high), killing over 160 in Hilo. A 100-foot tsunami wiped out a village in Alaska.
