Liquefaction is when saturated, sandy soil briefly behaves like a liquid in strong shaking. Across Kitsap, the higher-risk pockets tend to follow low shorelines and inlets. Parts of Bremerton, Manette and Silverdale all have mapped examples, often right beside lower-risk ground.

Mapped at a regional scale, so this can't settle the answer for a single parcel. That's why the map stops zooming here.
Three different earthquakes to plan around
Seattle Fault
A shallow fault zone beneath Bremerton, with a scarp across southern Bainbridge Island. It could also send a fast local tsunami through central Puget Sound.
Tacoma Fault
USGS scenarios run it from the Belfair area through Vashon Island toward Federal Way, though its eastern reach is uncertain.
Cascadia Subduction Zone
The offshore giant. Expect long, widespread shaking, followed by a tsunami that takes hours to work its way down into Puget Sound and Hood Canal.

How fast the water could arrive
In central Puget Sound, the Seattle Fault is the faster threat. If you're near the water and feel strong shaking, that shaking is your warning: move to high ground right away and don't wait for a siren.
