Using ultra-advanced seismic reflection technology akin to a geological ultrasound, scientists have captured a striking look at the Cascadia subduction zone “caught in the act of dying.” The data shows massive underwater faults and fractures tearing through the sinking Pacific tectonic plate. Instead of collapsing in one catastrophic event, the plate is snapping apart piece by piece, creating smaller microplates. Geologists describe the slow-motion phenomenon as watching a train derailment one car at a time beneath the ocean floor.
