  • 超高密度地震観測情報に基づく地盤震動特性の評価

Description

Tokyo Gas Co., Ltd. has deployed a real-time earthquake monitoring system, SUPREME, which employs approximately 4, 000 spectrum intensity (SI) sensors in their service area. Tokyo Gas gathered approximately 60, 000 borehole information, and the amplifications of SI are estimated in their service area. Recently, Metropolitan Seismic Observation network (MeSO-net) has been operated. This study evaluates the site amplification characteristics using the ground motion records obtained by SUPREME and MeSO-net, and the availability of geospatial data compiled by Tokyo Gas is discussed.
