Abstract

In this report, ground shaking characteristics in the residential area around Mashiki Town, Kumamoto Prefecture, Japan, are evaluated by dense microtremor array measurements. First, we conducted microtremor measurements at 365 sites in the residential land. H/V spectra were then calculated using the measurement records. Finally, fine distributions based on the peak (ridge) and trough frequencies of the H/V spectra were illustrated in the residential land. The relationships between the evaluated H/V spectra and the seismic damage will be useful in the future study on the strong motion estimation in the residential land of during the 2016 Kumamoto earthquake sequence.
