Tsunami expert clarifies Eureka's safety from massive wave threats

The Humboldt County Board of Supervisors held a regular meeting on March 18, 2025, where significant discussions focused on tsunami preparedness and public safety. The meeting included a public comment session, during which concerns were raised about the potential impact of a tsunami, specifically regarding the possibility of a 30-foot wave.

A representative from the Office of Emergency Services (OES) addressed these concerns by explaining the development of the tsunami inundation zone map. This map was created with input from the California Geological Survey, which modeled worst-case tsunami scenarios. The representative emphasized that the map includes a 30% error margin to account for unexpected wave heights, ensuring that safety zones are adequately defined.

Residents were encouraged to utilize the Redwood Coast Tsunami Work Group's website to access detailed tsunami hazard maps. These maps allow individuals to assess their specific locations and understand their risk levels. The representative reassured the public that while tsunami waves can be large at the coast, they lose energy as they move inland. Consequently, areas like Eureka have relatively small inundation zones, making it feasible for residents to evacuate quickly if necessary.

The meeting underscored the importance of community awareness and preparedness in the face of natural disasters, urging residents to familiarize themselves with evacuation routes and safety zones. The Board of Supervisors continues to prioritize public safety and disaster readiness in Humboldt County.
