Three-dimensional deep electrical resistivity structure beneath the Kii Peninsula, southwestern Japan: fluids and their contribution to seismic activities
By mapping the 3-D electrical resistivity structure beneath the Kii Peninsula, this study reveals that impermeable acidic plutons act as barriers to fluid migration from the subducting Philippine Sea slab, thereby controlling the accumulation of slab-derived fluids that trigger deep low-frequency earthquakes and guiding fluid flow that influences microseismicity.
