説明

The geology of the Yasukuni landslide area consists mainly of tuffaceous clastic rocks and acidic volcaniclastic rocks of the Upper Miocene Ikutawara Formation, in which an interstratified illite/smectite minerals zone exists, formed by hydrothermal alteration related to the 8.1-7.7 Ma Ryuo hydrothermal system. The slide clays and debris contain large amounts of interstratified illite/smectite minerals. The occurrence of the Yasukuni slide is strongly related to the unstable nature of the interstratified illite/smectite minerals zone, the bulk of which is swelling clay mineral. This fact is useful in evaluating landslide risk and creating a hazard map of such slides in ancient and active hydrothermal fields.
