Earth is splitting open beneath the Pacific Northwest, scientists say
Scientists have observed the Juan de Fuca tectonic plate splitting apart beneath the Pacific Northwest as it subducts under the North American plate, marking the first time a subduction zone has been seen in the process of breaking down. Using seismic imaging and earthquake data from the 2021 Cascadia Seismic Imaging Experiment, researchers found the plate is fragmenting piece by piece rather than collapsing all at once. The findings provide new insights into the life cycle of tectonic plates and may influence understanding of earthquake risks in the region.

Science News from research organizations Earth is splitting open beneath the Pacific Northwest, scientists say Date: April 29, 2026 Source: Columbia Climate School Summary: For the first time, scientists have watched a subduction zone literally fall apart beneath the ocean floor. Using advanced seismic imaging, they found the Juan de Fuca plate splitting into fragments as it sinks beneath North America. Rather than collapsing all at once, the plate is tearing piece by piece, like a train slowly derailing. The finding helps explain ancient plate fragments and could refine how scientists understand earthquake behavior.
