Scientists have issued a terrifying new warning — a massive earthquake and mega tsunami could strike the U.S. West Coast before the year 2100. The threat lies in the Cascadia Subduction Zone, a 620-mile-long fault line that could trigger catastrophic flooding across cities like Seattle, Portland, and parts of Northern California.<br /><br />With up to a 29% chance of a magnitude 8.0 or higher earthquake within the next 75 years, the potential impact is devastating: tens of thousands of buildings flooded, vital infrastructure wiped out, and farmland permanently destroyed by saltwater. And unlike hurricanes or wildfires, this disaster could strike with no warning at all.<br /><br />In this video, we break down the science behind the threat, the areas at greatest risk, and what this means for millions living along the Pacific Northwest.<br />WooGlobe Ref : WGA894400<br />For licensing and to use this video, please email licensing@wooglobe.com
