When earthquakes happen along this boundary, "they can be huge," Simms said. The Cascadia Subduction Zone is the boundary between two of Earth's big tectonic plates." However, that region overlies the Cascadia Subduction Zone. Jane Tyska/Digital First Media/East Bay Times/GettyĪlex Simms, Professor, Department of Earth Science at the University of California Santa Barbara told Newsweek: "The earthquake that happened was not the 'big one.'
