Southern Tohoku - Kanto districts:
Nakajima and Hasegawa (2006, GRL); Hirose et al. (2008, Zisin2); Nakajima et al. (2009, JGR)

Southwestern Japan:

Drawing procedure

  1. By downloading & decompressing data file (plate_data.tar.gz), "plate_data" folder is made.
  2. By using "contour_map_PHS.gmt" in the folder, depth contours of the Philippine Sea slab (contour_map_PHS.ps, PHS) is illustrated. (*)
  3. By using "contour_map_PAC.gmt" in the folder, depth contours of the Pacific slab (contour_map_PAC.ps, PAC) is illustrated. (*)

    *: Generic Mapping Tools (GMT) should have been installed in your PC.

Composition of plate data files

Pacific plate

[PAC]: Hokkaido - northern Tohoku districts[Kita et al. (2010, EPSL)]
     Northern - southern Tohoku[Nakajima and Hasegawa (2006, GRL)]
     Kanto district - northern Izu arc[Nakajima et al. (2009, JGR)]

*Note: Depth contours in the Pacific plate are illustrated by using GMT's interpolation command because data are composed every 0.2 degrees in latitude and longitude.

Philippine Sea plate

[sw]: southwestern Japan[Hirose et al. (2008, JGR)]
*: Depth contour of 20 km near the Kii peninsula of[Hirose et al. (2007, Zisin2)] is revised.

[kanto]: Kanto district[Hirose et al. (2008a, Zisin2)]

[izu3]: northern area of Izu island[Nakajima et al. (2009, JGR)]

[nakajima]: deeper part of the Philippine Sea slab[Nakajima and Hasegawa (2007, JGR)]

[baba]: depth contour of 10 km along the Nankai trough[Baba et al. (2002, PEPI)]
