Topography and 1D mantle structure models for NW Pacific. a Regional large-scale topography model (top) and local small-scale topography model for a site NM04 (bottom), discretized in the \(\left( {x_{1} ,y_{1} } \right)\) coordinate system (\(\theta_{1} = - 55\)°). North is up. Color indicates the bathymetry. The observation array or site locates the center of the regional or local model as indicated by a circle. b Same as a but in the \(\left( {x_{6} ,y_{6} } \right)\) coordinate system (\(\theta_{6} = 15\)°). c 1D electrical conductivity structure model after Baba et al. (2017b)
