Scientists Capture Subduction Zone Tearing Apart off Vancouver Island

Scientists have captured a subduction zone off Vancouver Island in the process of tearing itself apart, revealing that these massive tectonic systems may die piece by piece rather than all at once. This observation provides new insight into the behavior of tectonic structures beneath the Pacific Northwest.

The discovery could help explain ancient plate fragments and volcanic activity. It may also shed light on how hidden breaks beneath Cascadia influence future earthquakes.
