Philippine Sea plate

Philippine Sea plate unified based on the velocity structures by seismic tomography, seismicity, focal mechanisms, seismic reflection and refraction survey, receiver function analysis.

Data of southwestern Japan^{1, 3, 9}, Kanto district⁴, and northern area of Izu island¹⁰ are compiled. Green areas denote the estimated asperities or locked zone on the Philippine Sea slab^{7, 13}, and expected source region of the Tokai, Tonankai, Nankai earthquakes^{2, 15}. Blue areas denote the slow slip events^{5, 6, 8, 11, 12}. Arrows indicate direction of plate motion of the Philippine Sea plate relative to the continental plate¹⁴. Red triangles denote active volcanoes.
