Abstract: Slope failure rates may be exacerbated by increased precipitation patterns associated with climate change. Such events are extremely disruptive for local communities affected. Rapid engineering remediation solutions generally require immediate site characterization, including information on… read more here.

DOI: 10.1190/geo2018-0651.1
Abstract: The horizontal-to-vertical spectral-ratio (HVSR) analysis of ambient noise recordings is a popular reconnaissance tool used worldwide for seismic microzonation and earthquake site characterization. We have expanded this single-station passive HVSR technique to active multicomponent data.… read more here.

DOI: 10.20965/jdr.2025.p0628
Abstract: Since underground structures in the sea area are difficult to observe, they are not well examined. To estimate underground structures beneath Seafloor Observation Network for Earthquakes and Tsunamis along the Japan Trench (S-net), which was… read more here.
