This project is a study on volcanic disaster and mode of eruptions during historical time around the active crater of Nakadake, Aso volcano, Japan. The archaeological excavations were carried out at 7 places in the Furubochu area located at 1 to 1,5 km west from the crater. In all trenches we found the ruins of the Furubochu temples, which were covered with a lot of ash layers. They are culverts, floors earthworks, wood remains, and fragments of ceramics. The ^<14>C dates of organic relicts and fragments of charcoal indicate 15-17 century. Thick ash layers covering on ruins were subdivided into two groups, i.e. ash eruption products of upper group and phreatic or phreato-magmatic explosion products of lower group. And it was clarified that effusions of gas with volcanic ash originated from new magma was occurred through the hot water pool in the crater of Nakadake.

该项目是对日本阿苏火山中岳火山口周围历史时期火山灾害和喷发模式的研究。考古发掘在火山口以西 1 至 1.5 公里的古坊中地区的 7 个地点进行。在所有的战壕中，我们都发现了古坊中寺庙的遗址，上面覆盖着很多灰烬层。它们是涵洞、地板、土方工程、木材遗骸和陶瓷碎片。有机遗迹和木炭碎片的^14C年代表明15-17世纪。覆盖在遗址上的厚厚的灰层又分为两组，即上组的火山灰喷发产物和下组的潜水或潜水岩浆爆炸产物。并澄清，来自新岩浆的火山灰气体是通过中岳火山口的热水池喷出的。
