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.

本项目是对日本阿索火山中岳活火山口周围历史时期火山灾害和喷发模式的研究。考古发掘在古坊中地区的7个地方进行，位于火山口以西1至1.5公里处。在所有的战壕里，我们发现了古坊中寺庙的废墟，上面覆盖着大量的灰烬层。它们是涵洞、地板、土方工程、木材遗骸和陶瓷碎片。有机<14>残体和木炭碎片的^ C年代显示其形成于15-17世纪。覆盖在废墟上的厚灰层可分为两类，即上灰层喷发产物和下灰层潜水或潜水岩浆爆发产物。并澄清了新岩浆产生的火山灰气体通过中岳火山口的热水池喷出。
