SILVERDALE — Local naval bases will take part in Citadel Rumble, an annual earthquake response drill, from Monday through Friday.
The worldwide exercise is conducted by the Navy Installations Command.
The exercise tests the abilities of naval installations to respond to, and recover from, multiple hazards that could be triggered by a major earthquake.
Participating local installations include Naval Air Station Whidbey Island, Naval Base Kitsap, Naval Magazine Indian Island and Naval Station Everett.
People near one of these installations may hear messages over emergency notification loudspeakers or may see increased activity from emergency response personnel and vehicles.
