GRL: Fluid controls on the heterogeneous seismic characteristics of the Cascadia margin
By Jonathan Delph, Alan Levander, and Fenglin Niu Abstract: The dehydration of oceanic slabs during subduction is mainly thermally controlled and is often expressed as intermediate‐depth seismicity. In warm subduction zones, shallow dehydration can also lead to the buildup of pore‐fluid pressure near the plate interface, resulting in nonvolcanic tremor. Along the Cascadia margin, tremor […]
