Ground Motion Evaluation in Residential Area, Minami-Aso Village for the Main Shock of the 2016 Kumamoto Earthquake

Abstract

Residential landslides in Miami-Aso Village, which are located near the epicenter of the main shock of the 2016 Kumamoto Earthquake were occurred due to the strong motion. In this study, ground investigations were conducted at the landslide sites in order to evaluate the empirical site effects. Seismic waveforms at the sites of interest during the 2016 main shock were then estimated based on the site effects and the characterized source model. The estimated ground motions will be useful in the detailed study of the landslide mechanism.
