A weak layer, which caused these avalanches, was observed 30cm below the snow surface and was composed of solid type depth hoar. It is conjectured that this weak layer was formed under the following condition; fresh snow deposited between midnight of 1 and the morning of 2 January changed into a solid type depth hoar layer under the weak wind and cold condition on the morning of 3 January. A simulation using a numerical snowpack model with meteorological data also revealed a solid type depth hoar layer and demonstrated the availability of model to forecast avalanches. Although forests are considered to contribute to avalanche protection in general, this avalanche implied that we need to evaluate their effectiveness carefully.", "subitem_description_type":
