Background
The dacitic Kinunuma volcano produced a lava flow and pyroclastic flow about 0.24 or 0.20 million years ago. The Kinunuma-Kurodahara tephra consists of pumice fall deposits (~5 km3) and mostly-welded pyroclastic flow deposits (less than 1 km3), erupted at 0.20-0.24 Ma. Andesitic and dacitic lava domes of the Nenakusa-yama volcano to the SE were active about 0.3 million years ago.---
