Geophysical imaging of fluids in the Cascadia subduction zone

Water that has been carried deep into the Earth by oceanic plates in subduction zones, can influence earthquakes and volcanic eruptions. Three-dimensional images of electrical resistivity derived from electromagnetic geophysical data provide new constraints on the distribution, transport, and storage of water in the Cascadia subduction zone.
