Emergency Sirens

At noon on the first Wednesday of every month, we test the emergency siren warning system.

The test is a 30-second slow wail tone. 

If you hear a siren at different time, there is an an emergency in your area! 

You should turn your radio to one of the following local emergency broadcast news stations: KCBS (740 AM), KGO (810 AM) or KNBR (680 AM) to learn more about the emergency. 

Sirens sound during earthquakes, chemical spills, large fires, terrorist acts or other emergency events. 

The City of Oakland uses three different siren sounds. Each sound tells you how to stay safe during the emergency.

If you hear a 3-minute steady tone, you should shelter in place.

If you hear a 3-minute slow wail tone, a there might be a s Tsunami. 

If you hear a 3-minute fast wail tone, there is a fire.
