[s13e1] A Seismic Shift Instant

Scientists use the "seismic gap" theory to identify fault segments that haven't moved in a long time, marking them as the most likely locations for future massive ruptures. Immediate Hazards: Shaking and Inundation

A devastating tsunami could strike within 10 to 15 minutes of the initial shaking. The largest waves could reach heights of 100 feet , though coastal mountains and cliffs in areas like Oregon may provide a natural barrier to the water's eastward push. Preparation and Resilience Efforts [S13E1] A Seismic Shift

The Cascadia Subduction Zone (CSZ) is a unique tectonic fault where the is moving beneath the North American plate . Unlike other active zones, this fault is currently "locked" by friction, showing very little daily seismic activity, which allows massive amounts of stress to accumulate over time. Scientists use the "seismic gap" theory to identify

A major earthquake in this region would trigger a two-phase disaster involving both the land and the ocean. showing very little daily seismic activity
