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.

A new report describes geological rifting underway beneath the Pacific Northwest, where tectonic forces are slowly pulling the Earth's crust apart. The findings are drawing widespread attention, with readers sharing and discussing the story of the region's underlying seismic activity. Scientists point to the ongoing deformation of the Cascadia region as evidence of powerful forces reshaping the ocean floor and coastline over geological timescales.
