Landslide Hazard and Risk Assessment on the Northern Slope of Mt. Changbai, China

Landslide hazard and risk assessment on the northern slope of Mt.Changbai,a well-known tourist attraction near the North Korean-Chinese border,are assessed.This study is divided into two parts,namely,landslide hazard zonation and risk assessment.The 1992 Anbalagan and Singh method of landslide hazard zonation (LHZ)was modified and used in this area.In this way,an Associative Analysis Method was used in representative areas to get a measure for controlling factors (slope gradient,relative relief,vegetation,geology,discontinuity development,weak layer thickness and ground water).For the membership degree of factor to slope failure,the middle range of limited values was used to calculate LHZ.Based on an estimation of the potential damage from slope failure, a reasonable risk assessment map was obtained using the relationship of potential damage and probable hazard to aid future planning and prediction and to avert loss of life.
