Deep-sea landslides in the Pacific Northwest's Cascadia subduction zone hold a record of earthquakes dating back 7,500 years, and similar markers may be found in other tectonic plate boundaries ...

Even long-lived subduction zones eventually die, and scientists believe they are witnessing the slow death of one in the northern end of the Cascadia subduction zone. A new study using seismic data ...

For decades, the end-stage life of a subduction zone existed only in theory. Now, for the first time in geologic history, scientists are bearing witness to the Juan de Fuca Plate tearing apart and ...
