12 Miles WSW of Eureke Offshore of Humboldt County
Notes
At about this time on this morning in 1994 a M5.4 earthquake with an epicenter just offshore of Eureka, CA, along the coast of Humboldt County in Northern California jolted residents in the immediate area injuring about two dozen of them while knocking out power, breaking windows and doing widely scattered other minor damage. An interesting footnote to this event were the numerous reliable reports of strange photo-luminescent phenomenon in the sky over offshore epicenter area as the earthquake occurred.
