New study shows how massive Cascadia subduction zone earthquake would completely remake the Pacific coastline
- A new study published on April 28 shows a magnitude 8 Cascadia earthquake could lower coastal land up to 6.6 feet in northern California, Oregon, and Washington.
- Researchers led by Tina Dura compared flood risks if the earthquake occurs today or in 2100, factoring in predicted sea-level rise due to climate change.
- The study found coastal subsidence combined with rising seas could increase the 100-year floodplain by up to 145 square miles, putting 17,710 more residents at risk of flooding.
- Dura warned that land subsidence "could persist for centuries after the earthquake" and that it would "totally change these coastal communities," affecting evacuation and rebuilding.
- The findings suggest that expanded floodplain maps could improve emergency planning and highlight the need to adapt infrastructure to future coastal changes.

The Big One, coupled with rising ocean, could leave many in Northwest living in flood zones, study finds
If the once-every-500-year Cascadia Subduction Zone earthquake doesn’t do enough damage to the coastal Northwest on its own, frequent and widespread flooding from rising seas that follows will take care of the rest, new research found.Oregon, Washington and California are overdue for the recurring seismic event — popularly referred to as “The Big One” — which last occurred in 1700 and could cause Northwest coastlines to lower and retreat by more…

People Living On The West Coast Should Be Preparing For Cataclysmic Natural Disasters
This article was originally published by Michael Snyder at The End of the American Dream under the title: As The Ring Of Fire Becomes More Active, People Living On The West Coast Should Be Preparing For Cataclysmic Natural Disasters In recent months, we have seen a tremendous amount of seismic activity occur along the Ring of Fire. Sizable earthquakes have been popping off like firecrackers, and volcanic activity has risen to very alarming leve…
