运用历史航照及地形图建置数值地形资料并探讨1941年草岭山崩之地形演育(英文)

1941 Tasoling landside analysis based on aerial photos,topographic map and the associated DEM data

In tectonically active mountain belts such as the Taiwan(Fig.1a),frequent landslides affect the stability of mountain slopes,and landslides favour river erosion of disrupted masses.In the climatic and geodynamic context of Taiwan with heavy rainfall,approximate typhoon frequency of 3 -5 per year,rapid uplift of～5-10 mm yr^(-1) and strong denudation rate.Landslides are among the most common earthquake induced secondary effects and are causing huge damage

In tectonically active mountain belts such as the Taiwan （Fig. la）, frequent landslides affect the stability of mountain slopes, and landslides favour river erosion of disrupted masses. In the climatic and geodynamic context of Taiwan with heavy rainfall, approximate typhoon frequency of 3 5 per year , rapid uplift of -5-10 mm yr ^-1 and strong denudation rate . Landslides are among the most common earthquake induced secondary effects and are causing huge damage to settlements, infrastructure and human life worldwide.
