5 December 2024 - a 7.0 magnitude earthquake off the Northern California coast triggered a tsunami warning - which was cancelled, but not before sending coastal Californian residents into a panic.
Offshore earthquakes along the west coast of the United States leave little time to warn costal residents, so tsunami alerts are usually automatic - to err on the side of safety.
