| Research Abstract |
We investigated on the hillside disasters triggered by the 921 Chi-chi Earthquake, 21 Sep. 1999. On the schedule of investigation in 2001 year, survey of all members was carried out from 24 Sep. to 3 Oct., and each survey was carried out in July, Nov., Dec. and January.
In survey of all members, we arrived on Taiwan, investigated Kuang-fu Elementary School at Wu-feng 24 Sep.. We separated from next day 2 groups that are air photo group and filed survey group. The air photo group investigated analysis by air photo at Industrial Technology Research Institute. The filed survey group investigated the bare ridge at Chiu-chiu-feng, 25, and visited to Soil and Water Conservation Bureau to discuss and took the data and materials. They conducted survey of cross section of at Chiu-chiu-feng, 26. The filed survey group conducted ground survey at, Chiu-fen-erh-shan, 27.
