U.S. Navy installations in the Northwest region will conduct an earthquake and multi-hazard response exercise August 3-7, 2026. The participating installations include NAS Whidbey Island, Naval Station Everett, Naval Base Kitsap, and Naval Magazine Indian Island.
The annual exercise, called Citadel Rumble, will test Navy installations’ capabilities to prepare for, respond to and recover from an exercise scenario that includes multiple hazards triggered by a natural disaster. In this case, simulated earthquakes will trigger other simulated hazardous events.
People near the participating Navy installations 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 activity that might be observed includes messages played over the Navy’s emergency notification loudspeaker system and increased emergency response vehicle and personnel activity. The Navy aims to minimize impact to the public as much as possible during such exercises.
This exercise will provide Navy personnel the opportunity to exercise emergency management teams, processes, procedures and partnerships with local mutual aid agencies to be better prepared to respond to real-world disasters. The exercise will also further enhance the Navy’s readiness and ability to deploy forces even under the most adverse conditions.
The participating installations, along with their tenant commands, will test various procedures, including damage assessment, evacuation plans, disaster preparedness, recovery and consequence management plans, and accounting for Sailors and Navy families in the affected regions through the Navy Family Accountability and Assessment System.
Citadel Rumble, spearheaded by Commander, Navy Installations Command, is an annual fully-integrated disaster preparedness, response and recovery exercise that evaluates Navy Shore Emergency Management program readiness.
