Kitsap County is subject to inland tsunamis. Earthquakes or landslides are both potential causes. Land masses falling into the water can create a wave that would affect low-lying areas. Waves created by inland tsunamis can damage ports, marinas, or businesses on the waterfront. Based on the 2019 assessment of Kitsap County, tsunamis are rated a moderate risk hazard.
What is KCDEM doing to address tsunamis?
The Kitsap Department of Emergency Management (KCDEM) is participating in local and regional planning to address tsunami emergencies. Projects include:
- Partner with local governments to enhance tsunami evacuation signage.
- Partner with Puget Sound counties to study the impact of a catastrophic earthquake. Earthquakes can generate a tsunami that would impact ports and maritime operations.
- KCDEM is also active in state and local planning efforts. Learn more about the Cascadia Rising 2022.
