 note = {application/pdf, 紀要論文, An attempt is made to obtain a model for the mode of volcanic ash fall deposition in the present paper. Sakurajima volcano is examined as a case, which offers useful data such as height eruption column, upper wind velocity, grain size distribution and isopach maps of the volcanic ash. Though there are still many problems in the application of the diffusion theory, it is available to apply the Stokes' law to the mode of volcanic ash fall deposition. On the basis of this result, two empirical formulae are obtained. Using a model formula applied in general cases, it is expected to assume palaeo-climate and past volcanic activities.},
