Shallower Plate, Stronger Shaking in Oregon | Science News

New seismic mapping reveals northern Oregon could face stronger, longer shaking from future Cascadia earthquakes — thanks to a shallower Juan de Fuca plate and a hidden sedimentary basin near Tillamook that amplifies quake waves like a bowl of jelly. Scientists deployed 192 seismometers plus offshore data to create the most detailed subduction zone map yet, raising hazard estimates by 9–17% and urging closer scrutiny of basins like Portland’s Tualatin Basin.
