HOW TO USE HAZARD MAPS?
Five levels of relative susceptibility have been identified on the KMA Landslide Susceptibility Maps:
(1) low; (2) moderate; (3) moderate-high; (4) high; and (5) very high.
Predicting absolute hazard is impractical with current capabilities.
These zones do not imply legal restriction or regulation by zoning ordinances or laws as laid down by the local government authorities.
Citizens, planners, engineers, and developers, however, can use these landslide hazard zonation maps as a tool to help reduce losses from existing and future landslides through prevention, mitigation, and / or avoidance.
The map is intended primarily for the assessment of landslide hazard for planning
purposes on a regional scale.
Map indicates indirectly the extent and relative severity of landslide hazard and may be used in preliminary selection of areas for housing and infrastructural development.
The enhanced readability of the map far outweighs the simplifications, errors and, omissions that could not be avoided.
The map should not be used to determine the stability of specific building sites.
The map can be used to identify areas where detailed geologic-geotechnical investigations are desirable prior to the development.
Citizens may use the map in a general way to determine relative hazard, because chances of landslides occurring in areas in a high susceptibility zone (4) are greater than in areas under low zone (1).
IT SHOULD BE UNDERSTOOD THAT NATURAL CHANGES AS WELL AS HUMAN-INDUCED CHANGES CAN AFFECT THE SUSCEPTIBILITY TO LANDSLIDES IN ANY AREA, AND THAT THE ABSENCE OF PAST OR PRESENT LANDSLIDES DOES NOT MEAN THAT SLOPE FAILURES WILL NOT OCCUR IN THE FUTURE.
