| Research Abstract |
In order to evaluate the frequency of small-scale eruption in a volcano, the purpose of this study is to establish a method for detecting the tracks indicating the eruptive episode in volcanic soils. It is proved that the existence of a clay mineral implies thesmall-scale eruptive event, but it is difficult to reconstruct the volcanic activity for a very small content of this clay mineral. On the other hand, radiocarbon age obtained from the sample of age known was good agreement with the old document. This result indicates that it is possible to decide the precise age by this 14C wiggle-matching method.
