| | Abstract | | We estimated the subsurface structures using microtremor array observation data at the port and airport in Satsuma-Iwojima Island. Subsurface structures from the surface to the soil layers of Vs=2000m/s were estimated considering both the H/V spectral ratios and the dispersion curves of phase velocity. The airport is thought to be on an outer rim of a volcanic crater of Kikai Caldera and the shallow subsurface structure of Vs |
