Geology and Countermeasure of Landslides in Northwestern Part of Yamaguchi Prefecture, Japan
Bibliographic record
Abstract
山口県北西部の日本海に沿って，東西に油谷半島の付け根付近から半島先端を経て角島に至るまで，古第三紀後期漸新世から新第三紀中期中新世の堆積岩が分布している．この基盤岩は後期中新世に噴出した玄武岩の溶岩流によって被覆されている．この溶岩流によって形成された溶岩台地は，その後の地すべりや海水面の作用で侵食や運搬を受け，半島の尾根部にキャップロックとして残されている．この漸新-中新統堆積岩類は，十分固結していない段階から，玄武岩の荷重と地下水の供給を受け，堆積岩内あるいは境界付近をすべり面とする大規模地すべりが発生した．この大規模地すべり域では初生的な地すべりの後に少なくとも2回の地すべりの痕跡が残れている．本案内書では初生的な地すべりを1次地すべり，1次地すべりにより形成された地すべり土塊が，再度すべったものを2次地すべり，さらに表層部のみがすべったものを3次地すべりとする．本地域は，2次，3次地すべりを対象として｢地すべり防止区域｣に指定され，地すべり工事が実施されてきた．今回の巡検では代表的な地すべり地を巡り，山口県北西部日本海岸の地質との関連を紹介するだけでなく，最近の研究成果による詳細な地すべり滑動のメカニズム，解析手法，対策工事についても議論する．

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
