Helium isotopes from groundwater and hot springs at the stratovolcano, Unzen, have a stronger mantle signature than for the nearby caldera volcano, Aso, which suggests that magma at Unzen is younger still supplied with primordial mantle helium.

Abstract Plate bending-related normal faults (i.e. bend-faults) develop at the outer trench-slope of the oceanic plate incoming into the subduction zone. Numerous geophysical studies and numerical simulations suggest that bend-faults play a key role
