Especially the Muramoto rock quarry, which is main field trip stop in our class with big cliff and diggings hole, was highly occur land slide. Debris flow occurred during the land sliding started top of the hill (850m). Then this flow down bottom of digging hole then it clime up again opposite side of the lower cliff (30m from bottom of cliff). There are several big concrete water pipes and rock breccia within mud flow deposit. If these is not diggings holes in this quarry, debris flow went to village bellow this quarry. So it is suggest that high energy debris flow easy can pass higher mound.
