Fig. 5From: Microtremor array surveys and development of the velocity model in the Hakodate Plain, Hokkaido, JapanTarget area for modeling velocity structure in the Hakodate Plain. The target area for constructing the new velocity structure model (red frame) and locations of control points (blue: microtremor array surveys, magenta: reflection surveys by Sato et al. (2019), pink: reflection surveys by Japan National Oil Corporation (JNOC) 1981) are shown.
