The Cascadia Subduction Zone is a 700-mile-long fault that runs from Northern California to British Columbia. Scientists currently predict a 37% chance that a megathrust earthquake of 7.1 magnitude or greater will occur within the next 50 years in this fault zone—one of the main reasons our region needs a replacement bridge designed to withstand such a disaster. | Interstate Bridge Replacement Program

🚨 Alert: Megathrust Zone - The Cascadia Fault Is Overdue We worry about the San Andreas, but the fault that can change the map is Cascadia, a 600-mile megathrust off Washington and Oregon. Scientists train for a Magnitude 9.0 event that can shake Seattle and Portland and send a local tsunami racing toward the coast in about 15 minutes after the shaking stops. 🌊 What history tells us: in 1700, Cascadia ruptured at ~M9.0 and launched a Pacific-wide tsunami recorded in Japan.

⚠️ 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
