Scientists have just uncovered a terrifying possibility — a megaquake on the Cascadia Fault could trigger another massive earthquake along California’s San Andreas Fault, striking within minutes or hours.
This new research suggests that the Big One might not be a solo disaster… but a deadly domino effect that could devastate the entire West Coast, hitting San Francisco, Portland, Seattle, and Vancouver all at once.
The study, backed by over 20 years of research, found evidence of 18 massive earthquakes in Cascadia followed by quakes on the northern San Andreas over the past 3,000 years. The last time this happened? A magnitude 9 quake in 1700 that caused a tsunami in Japan and may have also triggered a major quake in Northern California.
Cascadia has a 37% chance of producing another megaquake in the next 50 years. And now, we know it might not strike alone. WooGlobe Ref : WGA782444 For licensing and to use this video, please email licensing@wooglobe.com
