• Imaging results: The imaging revealed deep fractures in the Juan de Fuca plate, including one where the descending oceanic slab has dropped approximately 3.1 miles (5 kilometers).
• Earthquake records: Analysis of earthquake data supported the seismic images. Along a 47-mile (75-kilometer) tear, some areas show continued seismic activity, while others are eerily quiet. This "missing seismicity" indicates that sections of the plate have already fully detached. 

the Cascadia subduction zone, located off the Pacific Northwest coast, actively tearing itself apart. Rather than shutting down abruptly in a single event, the oceanic plate is undergoing a gradual, episodic collapse that is creating smaller microplates. This slow-motion unraveling was documented in a study published in Science Advances in September 2025. How scientists made the discovery

The breakthrough discovery was made possible by the 2021 Cascadia Seismic Imaging Experiment (CASIE21), which was funded by the National Science Foundation.
