Humboldt County on the Northern California coast sits at the junction of the Gorda Juan de Fuca and North American tectonic plates — one of the most seismically active regions in the continental US. A magnitude 6.4 earthquake struck near Ferndale in December 2022 injuring dozens and cutting power to thousands. Tsunami risk from Cascadia Subduction Zone events is extremely serious for Eureka and coastal communities. Cal Poly Humboldt creates institutional emergency planning requirements.
