Pacific Northwest Fault Zone Raises Fresh Alarm Over Cascadia Megathrust Risk
New scientific reporting is renewing attention on the Cascadia Subduction Zone, where the Juan de Fuca Plate is slowly diving beneath North America and deforming the Pacific Northwest coastline. The concern is not immediate collapse, but the long-term accumulation of strain that could one day trigger a catastrophic earthquake and tsunami with consequences far beyond the region. For clean energy planners, coastal infrastructure operators and climate resilience officials, the warning underscores a harder truth: the energy transition is unfolding across a landscape where seismic risk, ports, transmission corridors and low-lying communities are tightly intertwined.
