What are the long-term consequences of land subsidence following a Cascadia earthquake, and how will this impact coastal communities?

A major earthquake along the Cascadia Subduction Zone could cause coastal land to drop up to 6.5 feet, leading to prolonged flooding in towns like Seaside, Oregon, and Westport, Washington. This subsidence, lasting decades to centuries, will exacerbate existing flood risks and significantly increase the number of people and structures affected beyond initial tsunami damage. The effects will worsen with rising sea levels from climate change.
