説明
昭和59年9月14日,午前8時48分に生じた長野県西部地震(M6.9) が同県木曽郡王滝村を中心に多大な被害をもたらしたが,筆者等はこの度被災地へ赴き,王滝川に沿う地すべり・土砂流の猛威の跡を見聞する機会を得たので,その状況を報告し,水工学的な見地からこの災害が我々に投げかける諸問題を考察する。
An earthquake with the magnitude of 6.9 attacked the west part of Nagano prefecture on the 14th of September 1984. The number of persons reported killed or missing was concentrated in Otaki village,where residents were buried under two big landslides and a heavy debris flow. The worst damage,heavy debris flow,was caused by the collapse of a ridge near the summit of Mt. Ontake (E.L. 3063m) at the height of 2800m. The debris flowed down the valley of Nigorigawa Riv.,jumped over a ridge with a height of 100m,locatedat the junction with the valley of Otakigawa Riv.,and piled along the valley 4km in length and 30m in thickness. The authors visited the above village and observed the sites of the mass movement. The paper deals mainly with the hydraulic mechanism of the debris flow based upon observed facts offered by the inhabitants of the village. In addition,a brief review of the historical disasters accompanied with landslides both in japan and around the world is included.
