Eureka California is the largest city on the Northern California coast and sits in Humboldt Bay — one of the few natural harbors on the Pacific coast between San Francisco and Astoria. The city is extremely isolated — US Highway 101 is the primary connection and floods or slides can cut the community off entirely. Humboldt County sits near the Cascadia Subduction Zone and the offshore Mendocino Triple Junction — one of the most seismically complex areas in North America. Tsunami risk is extreme and the city hosts the National Weather Service office for the region.
