2. Kita-mamedani and Ohmametani: The extremely
low magnetic anomaly area from the middle
to the upper area of the landslide correlates with the
layer thickness of the landslide colluvium. In addition,
a thin depositional area of the landslide colluvium
on the lower slope soil corresponds to the places
where the Funatsu granite shows high magnetic
anomaly. The thick detritus from the landslide collapse
is concordant with the low magnetic anomaly
found by RTP transformation. In addition, the thin detritus
area in the lower part of the slope shows high
magnetic anomaly, which is likely caused by the
strongly magnetized Funatsu granitic basement.
