Volcanic arcs are produced by these regions where the lithosphere enters the asthenosphere.
One of these entities near the Tokai district of Honshu had been studied by Kiyoo, who together with Caltech professor Hugo were the namesakes of the Wadati-Benioff regions. The cities of Victoria, Vancouver, Portland, and Seattle lie on one of these entities named Cascadia. Volcanic arcs are produced by these regions where the lithosphere enters the asthenosphere. Taking place at convergent plate boundaries, for 10 points, name these geological regions or processes where one tectonic plate sinks into the Earth's mantle by moving under another tectonic plate, thus causing violent volcanic eruptions and destructive earthquakes.
