Residents across Humboldt, Del Norte, and Mendocino counties are encouraged to participate in the annual North Coast Tsunami Drill on Wednesday, March 25, at 11 a.m. This exercise is coordinated by the Humboldt, Del Norte, and Mendocino counties’ Offices of Emergency Services, the National Weather Service in Eureka, and with the Redwood Coast Tsunami Work Group. The goal of this drill is to provide an opportunity for individuals, businesses, and organizations to practice earthquake and tsunami preparedness for a locally felt earthquake and tsunami.
On March 25 at 11 a.m., if you are in a tsunami zone, practice your evacuation plan by walking to higher ground or outside the tsunami hazard area. If you are not in a tsunami zone, stay where you are, evacuation is not necessary. Instead, use this time to consider how you would respond after an earthquake resulting in major damage.
Keep in mind that dangerous tsunami waves can continue for 24 to 48 hours after the first wave arrives. In a real event, do not return to the tsunami hazard area until officials confirm it is safe.
