In the event of a Cascadia Subduction Zone earthquake and tsunami, coastal populations will become isolated into “islands” due to landslides, liquefaction, and damaged infrastructure like bridges.
Oregon
The Oregon Office of Emergency Management’s “Island Mapping Pilot Project” mapped coastal populations in relation to likely infrastructure damage after an earthquake and tsunami. These maps show where transportation infrastructure will be damaged (bridge failure, landslide, liquefaction) causing populations to be isolated into “islands”.
