Studi Pendahuluan Potensi Bencana Alam (Geo-Disaster) Di Pulau Bangka
Abstract
The study area is a tin mining region in hundred years, located in Bangka Island, Bangka Belitung
Archipelago Province. Identifying geo-disaster potential, in order that to know the the type, spatial
distribution of geo-disaster that caused by geogenic or antropogenic factor. The research is done by
observing all of geo-disaster potential, with geological and geomophological additional condition. Geodisaster
potential is ilustratrated in a map as result of work using geographic information system (GIS)
software that is supported from Landsat TM7 analysis. Erosion, sedimentation, lanslide and
abration disaster mainly caused by antropogenic factors from tin mining activities and landfarming, but
for dryness, flood, hurricane and earthquake caused by geogenic factors. For flood and dryness also
influenced by antropogenic factor. Dryness, erosion and sedimentation has the large spatial
distribution in Bangka Island.
