Cascadia Subduction Zone

Caption

Map shows the Cascadia Subduction Zone along the Pacific Northwest coast, with a shaded area encompassing the onshore and offshore areas where seismometers were located. Data from the seismometers helped University of Oregon researchers identify seismic anomalies at both ends of the fault where they believe pieces of the upper mantle are rising and modulating earthquake activity.
