Naval Air Station Whidbey Island is among the Navy installations in the Northwest conducting earthquake response and recovery exercises through Aug. 9.

The annual exercise, called Citadel Rumble, will test Navy installations’ capabilities to respond to and recover from an exercise scenario that includes multiple hazards. In this case, simulated major earthquakes will trigger other simulated hazardous events, the Navy reported.

People near NAS Whidbey may see or hear activities related to the multi-day exercise, but this activity is not expected to impact the public outside of Navy property. Exercise activities that could potentially be observed include messages played over the Navy’s emergency notification loudspeaker system and increased emergency response vehicle and personnel activity.
