Beschreibung:The caldera-forming eruption of Nigorikawa volcano produced pyroclastic-fall and -surge deposits and pyroclastic-flow deposits that extend northward and westward to the Pacific coast. The town of Nigorigawa is located on the bottom of the flat caldera floor. The Nigorigawa river drains the area through a gap of the NW caldera rim. |
