Keywords:amount of fall-out ashs, photo images

When the volcano erupted, to estimate the eruptive mass of magma is important in revealing the scale of the eruption. However, in order to estimate the amount of fall-out ashes, it requires many field works. In these days, it is possible to know the appearance of fall-out ashes to immediate through the Internet media such as SNS. In this study, we conducted filed survey at the time of actual fall-out ashes from Sakurajima and Aso volcanoes. Also it was carried out fall-out ashes from Sakurajima volcano measurement by experiment. And we tried estimation method for the amount of the fall-out ashes using the photo images. From the images obtained by the fall-out ashes measurement by experiment, it can be said that it is possible to grasp weight per unit area of approximately.
