A 9.0 megathrust earthquake along the Cascadia Subduction Zone would be one of the most destructive disasters in North American history. Scientists warn the 1,000 km fault from Vancouver Island to Northern California is capable of minutes of violent shaking, massive ground rupture, and a tsunami arriving within 15–30 minutes. This 15-second cinematic simulation shows how quickly the event could unfold — from the violent plate rupture offshore to the shaking in major cities like Seattle, Portland

The Cascadia Megathrust: On this day, 326 years ago For centuries leading up to January 26, 1700, an oceanic plate was slowly pushing beneath North America off the Pacific Northwest coast—moving just inches per year as stress quietly built underground. On January 26, 1700, that locked boundary gave way. The plates suddenly slipped, releasing centuries of stored energy and triggering a massive earthquake that ruptured the Cascadia Subduction Zone. Fault systems like Cascadia can remain quiet for

⚠️ PACIFIC NORTHWEST 9.0 MEGAQUAKE RISK The Cascadia Subduction Zone is a 1,000 km megathrust fault off the coasts of Vancouver Island, Washington, Oregon and northern California. Geological records from drowned forests, sand sheets and offshore cores show that Cascadia has produced many great earthquakes over the last 10,000 years, with full-margin ruptures repeating on the order of hundreds of years. A new line of research looks at the relationship between Cascadia and the San Andreas Fault. A
