Figure 6From: Markov random field modeling for mapping geofluid distributions from seismic velocity structuresObserved tomographic data ( Matsubara et al. 2008) at the depth of 40 km used in this study. P-wave and S-wave velocities (VP (left) and VS (right)) and their ratio (VP/VS, bottom) are shown. Closed triangles indicate the Quaternary volcanoes.Back to article page
