In coordination with CalOES, Humboldt County, Del Norte County, Mendocino County, local tribal governments, and the Redwood Coast Tsunami Work Group; the National Weather Service in Eureka, California will be conducting a test of the tsunami warning communications system on March 25th between 11 am and noon. The test will simulate the dissemination of a tsunami warning for a large tsunami wave originating from far away, such as in Alaska or Japan. Examples of events like this in the past include 1964 (Alaska) and 2011 (Japan) when tsunami waves hit our coastline from far away.
The test will trigger the Emergency Alert System (EAS) across the three county area resulting in alerts on radio and TV broadcasts, weather radio, and tsunami sirens in some areas. People on the coast may also hear test broadcasts from airplanes and receive reverse calling alerts from county governments. The Wireless Emergency Alerts (WEA) system for cellular phones will NOT be tested, but in a real emergency it would be activated for a Tsunami Warning.
