| Research Abstract |
Catastrophic outburst floods by a breach of volcanic dam or caldera rim can cause large-magnitude ones with large volume of impounded water with sediments. The extreme floods can travel long distance from the source volcano that ultimately affect onto landform and hydrology further downstream areas and threaten human life and economy eventually. This research focused on geomorphic and sedimentary features in the Oirase River catchment area and Towada caldera lake, and the Shira River catchment area and Aso caldera. Those imply volcanogenic catastrophic floods by dambreak of caldera lakes after ignimbrite eruptions.
