Mapping slope hazard

Urban expansion spurs development on hazard-prone hillside land. Taiwan’s Central Geological Survey launched in 2002 a five-year geological survey to map potential hazards and improve disaster prevention. Falling rocks, landslides, coal mining areas, abandoned quarries, river bank erosion etc. were all taken into account to build a comprehensive hazard prevention database. MAA took part into this effort by mapping out and adding to this database slope hazard data for Northern Taiwan.
