Research Abstract |
We carried out geological and petrological investigations to reveal the source and age of a large-scale lahar deposit in the Lower Naka River、around Mito city. The lahar deposit can be correlated with one of the largest debris avalanche deposit in the Upper Naka River、which had been derived from Nasu volcanic group during the last 60 ky.
