In subduction zones, the sites of the world's largest earthquakes, tectonic activity may generate a "pump" that transports ...

Subduction will likely continue on either side of the tear and deformation may become more distributed across the region. In ...

The Cascadia Subduction Zone off the Pacific Northwest is overdue for an earthquake – and when it happens, coastal communities will be devastated.
