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

Jan. 26, 1700 is the last time a 9.0 earthquake and tsunami started on the Cascadia Subduction Zone. We know the exact date of the tsunami, Jan. 26, 1700, because the tsunami eventually hit Japan and the Japanese recorded it as an "orphan" tsunami. Geologic records on the Washington state coast match that approximate date, as well. Our Hazards and Outreach team are here to tell you a bit more about this event, but more importantly, what you can do to be more prepared for the next one. | Washingt

In a recent Wired article entitled, "The Long-Lost Tale of an 18th-Century Tsunami, as Told by Trees" new evidence for the Cascadia tsunami of 1700 is brought to light by examining tree rings on the U.S. Pacific coast. This SOS dataset shows the 1700 Cascadia tsunami modeled by the NOAA Pacific Tsunami Warning Center RIFT model. Earthquakes like this one (magnitude 8 or 9) along the Juan de Fuca plate on the coast of Washington, Oregon, California, and British Columbia are thought to happen ever

In the winter of 1700, the Pacific Northwest experienced one of the largest earthquakes ever recorded. The Cascadia Subduction Zone, a fault stretching from Vancouver Island to northern California, slipped and caused a massive earthquake estimated to be around magnitude 9.0. What makes this event even more remarkable is not just its sheer magnitude but its far-reaching effects. Hours after the tremors stopped, a powerful tsunami was unleashed across the Pacific Ocean. The tsunami generated by th
