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

🚨Cascadia Fault: 6.0 Earthquake Just Hit Off Oregon Cascadia’s offshore fault system just reminded us it is alive. A magnitude 6.0 earthquake hit off the Oregon coast at 7:25 p.m. Pacific on January 15, 2026, about 183 miles west of Bandon at a shallow depth of roughly 10 km. USGS says shaking on land was light and there was no tsunami, but that is not the whole story. This quake struck on the offshore plate boundary in front of the Cascadia Subduction Zone, one of the most dangerous earthquake
