Simulation of rock avalanche initiated by collapse of Unzen lava dome in case of large earthquake
Bibliographic record
Abstract
2008年5月12日に発生した四川大地震により, 速度が40m/sec以上の高速の岩盤崩壊が多く発生した。日本でも, 雲仙地区で大地震が発生した場合, 溶岩ドームが崩壊して, 岩塊が高速で流下し, 島原市の市街地に被害を及ぼすことが危惧される。本論文では, まず, 3次元地震応答解析を行い, 雲仙地区の溶岩ドームの震動特性を検討した。次に, 3次元地震応答解析の結果に基づき, 溶岩ドームの岩塊に加速度とその方位角を地震力として与え, 3次元個別要素法による高速岩盤崩壊シミュレーションを実施した。その結果, 流下速度の点において四川大地震でみられる高速の岩盤崩壊現象を説明できるものとなっている。また3次元個別要素法では, 3DECの改良により, 岩塊の接触形態を考慮したより実用的な物理モデルを反映させながら, 計算時間を大幅に短縮することができた。

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
