From: Seismogenesis of dual subduction beneath Kanto, central Japan controlled by fluid release
Slab surface temperature and mantle flow distribution. (A) Numerical experiment with a single plate (Pacific). Red and blight blue tubes depict the mantle wedge flow in two regions. Note the trench normal mantle flow in both areas (shown as red and blue arrows). (B) Numerical experiment with double subduction (Philippine Sea plate is shown as a semitransparent surface). Note the complex toroidal mantle flow underneath the Philippine Sea plate. (C) Temperature distribution inside the Philippine Sea plate. Black dots represent seismicity. Pacific plate is shown as a semitransparent surface. Blue arrows represent the mantle flow around the bottom of the Philippine Sea plate.
