BackgroundThe poorly defined 5.5 x 7 km wide caldera formed during eruptions about 73,000 and 45,000 years ago. It contains a cluster of 4 dacitic lava domes of Holocene age surrounding the 400-m-wide lake-filled Katanuma crater. The highest of the low, but steep-sided lava domes, Oga-dake, lies SE of the lake and reaches only 470 m above sea level. Oga-dake and Kurumiga-dake domes are capped by conglomerates and mudstones uplifted during dome growth.
