Cascadia Subduction Zone

The Cascadia Subduction Zone is a geological area located off the coast of the Pacific Northwest, where the Juan de Fuca Plate is sliding beneath the North American Plate. This convergence can create powerful earthquakes and volcanic activity, affecting regions from Northern California to British Columbia. The zone is notable for its potential to produce large-scale earthquakes, known as "megathrust" earthquakes, which can have significant impacts on nearby communities. Scientists closely monitor the region to understand its seismic activity and assess risks to ensure better preparedness for future events.
