Distribution of terrestrial heat flow. a Plots the heat flow rate at each measurement point. The circles indicate the heat flow at the Hi-net station, and the squares indicate the heat flow at the DTPBJ (Sakagawa et al. 2004). b Is plotted by interpolation using the Nearest neighbor method (nearest neighbor method). The grid size is set to 4Â min. Triangles in c indicate volcanoes in Northeastern Japan. The red dashed line indicates the volcanic front (Yoshida et al. 2013). The green hatch area indicates the location of the Ou Backbone Range. Dashed continuous lines indicate depth (km) contours to the top of the subducted Pacific plate (PAC) slab (Iwasaki et al. 2015; Lindquist et al. 2004)
