"San Francisco uses a combination of technologies and methods - including Alert SF, Wireless Emergency Alerts, social media, community networks, and public safety vehicles equipped with public address systems and lights. These tools were used successfully to evacuate Ocean Beach and the Great Highway in December, 2024 during a tsunami warning."
"The San Francisco Department of Emergency Management shut the sirens down over hardware and security issues in 2019. Originally expected to be upgraded at a cost of $2 million to $2.5 million, the repairs were never completed and the sirens remain silent."
San Francisco's iconic emergency sirens, shut down in 2019 for hardware and security repairs, remain non-functional despite an estimated $2 million to $2.5 million upgrade cost. A 2023 attempt to fund repairs through legislation failed to secure budget approval from the mayor's office. The FBI warning of potential Iranian drone attacks has renewed attention on the city's emergency warning capabilities. The San Francisco Department of Emergency Management now relies on alternative notification systems including Alert SF, Wireless Emergency Alerts, social media, community networks, and public safety vehicles with public address systems. These methods were successfully deployed during a December 2024 tsunami warning.
