Northern California issues rare tsunami warning after earthquake but cancels it quickly

Northern California experienced a rare tsunami warning on Thursday after a 7.0 magnitude earthquake struck near Ferndale. The National Weather Service issued the alert quickly but canceled it within an hour after determining there was no significant tsunami threat. In response to the warning, some cities ordered evacuations while others used social media to inform residents. The alert prompted mixed reactions, with some people seeking higher ground and others heading to the beach for a better view. Authorities took various actions, including evacuating areas in Eureka and halting transit in the San Francisco Bay Area. Critics noted the absence of emergency sirens in San Francisco, which have been out of service since 2019.
