Pacific Northwest

Scientists have captured a subduction zone off Vancouver Island in the process of tearing itself apart, suggesting these massive tectonic systems may die piece by piece rather than all at once. The finding offers new insight into how subduction zones end over geological time, with implications for understanding seismic hazards in the Pacific Northwest, where the Cascadia zone poses earthquake and tsunami risks.

New research reported by ScienceDaily describes geological activity tearing apart the Earth's crust beneath the Pacific Northwest of North America. The finding concerns the Cascadia region, where tectonic forces are said to be slowly splitting the seabed and coastal crust. Geologists say the discovery sheds light on how tectonic plates deform and how the region's earthquake hazards may evolve over time.
