Kurashita Landslide
Kurashita landslide (Japanese: 倉下地すべり） is located in Hakuba-Mura, Kitaazumi-Gun, Nagano Prefecture, Japan. The landslide is 800 m long and 800 m wide covering about 78 hectors of land. The landslide is divided into five blocks, labeled Block A through Block E. The area holds cultural significance as part of Hakuba-Mura, host of the 1998 Nagano Winter Olympics, and remains a major tourist destination. Geology Kurashita landslide, located near the Fossa Magna (Itoigawa-Shizuoka Tectonic Line), is part of one of Japan's most active tectonic regions. Ongoing tectonic movements since the Permian Period have created a complex geological structure, making the area prone to landslides. Geologically, the area consists of Jurassic shallow marine deposits, quartz andesite, and Lower Tertiary welded tuff, underlain by Permian to Triassic shale, sandstone, and conglomerate, resting on serpentine melange basement rocks. These layers were mixed and faulted over time. The active Bloc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kamenose Landslide
The Kamenose Landslide (Japanese: 亀の背地すべり, Kamenose Jisuberi) is a historically significant and geologically active landslide Landslides, also known as landslips, rockslips or rockslides, are several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, mudflows, shallow or deep-seated slope failures and debris flows. Landslides ... located in Osaka Prefecture, Japan, along the Yamato River basin. Known for its recurring mass movements and complex geological structure, the Kamenose Landslide has posed a persistent threat to local communities, transportation routes, and infrastructure for centuries. Geography and Location The Kamenose Landslide is situated in the eastern part of Osaka Prefecture, near the boundary with Nara Prefecture, along the foothills of the Ikoma Mountains. The geology of the Kamenose area is complex and comprises primarily alternating layers of sandstone and mudstone, along with weathered granite and vo ...

Harabun Landslide
Harabun Landslide is an urban landslide that occurred on July 7, 1997, in Harabun-Cho, a district in Sasebo City, Nagasaki Prefecture, Japan. Triggered by an unusually intense and prolonged rainfall event, the landslide caused extensive destruction to homes, roads, and lifelines in the area, forcing the evacuation of dozens of families and highlighting the risks associated with urban development on unstable slopes. The landslide covers an area of approximately 0.3 hectares, with length of 70 meters and width of 50. The depth is about 10 meters. The total volume of displaced material was estimated at 17,000 cubic meters. Geology Geologically, the site is underlain by Upper Tertiary mudstone and sandstone and overlain by a basaltic caprock. Beneath lies evidence of ancient landslide deposits, indicating a history of slope instability. The landslide occurred at the base of a steep slope situated along an alluvial plain. The moving mass was composed of clayey colluvium derived from vol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
