In Geology. A convergent boundary with no subduction is a continental-continental boundary. Because oceanic crust is denser than continental crust, it is always the subducting plate in a â¦ oceanic-continental boundary.In an oceanic-oceanic boundary, one of the plates will subduct, depending on several factors.ecause oceanic crust is denser than continental crust, it is always the subducting plate in a â¦ oceanic-continental boundary.

The Cascadia Subduction Zone (CSZ) is a 1,000 km (620 mi) long dipping fault that stretches from Northern Vancouver Island to Cape Mendocino in northern California.It separates the Juan de Fuca and North America plates. New Juan de Fuca plate is created offshore along the Juan de Fuca Ridge.ectonic processes active in the Cascadia subduction zone region include accretion, subduction, deep earthquakes, and active volcanism of the Cascades. This volcanism has included such notable eruptions as Mount Mazama (Crater Lake) about 7,500 years ago, Mount Meager about 2,350 years ago, and Mount St. Helens in 1980.
