Cascadia Has Been Quiet for Centuries So Why Could a Tsunami Strike?

The Cascadia Subduction Zone is one of the most powerful earthquake zones in North America. Stretching along the Pacific Northwest, it lies beneath parts of British Columbia, Washington, Oregon, and Northern California. Unlike regions where earthquakes happen frequently, Cascadia can remain remarkably quiet for long periods of time — but that silence does not mean the fault is inactive. Scientists know that the fault has produced massive earthquakes and tsunamis in the past, with the last major rupture occurring in 1700. Today, millions of people live in communities across the region, surrounded by infrastructure that could be heavily affected by a major earthquake and tsunami. So why is Cascadia’s silence so concerning? What happens when a fault capable of producing a massive earthquake stays quiet for centuries? #Cascadia #CascadiaSubductionZone #Earthquake #EarthquakeRisk #MegathrustEarthquake #PacificNorthwest #Washington #Oregon #BritishColumbia #California #Tsunami #EarthquakeScience #Geology #NaturalDisaster #EarthquakeHistory #DisasterPreparedness #USGeography #GeographyDocumentary #ScienceDocumentary #NaturalDisasters
