Tectonic environment and crust thickness in the area around Japan. Tectonic environment in the area around Japan. The blue lines denote the plate boundaries, and the gray lines illustrate the isodepth contours of the Moho depth in kilometers derived from the CRUST 1.0 model (Laske et al. 2013). The red triangles and lines denote active volcanoes and the volcanic front, respectively. The major features in the Sea of Japan are marked as follows: JB, Japan Basin; YB, Yamato Basin; TB, Tsushima Basin; YR, Yamato Rise.
