| Zusammenfassung |
| The potential contribution of remote sensing and GIS techniques to earthquake
hazard analysis was investigated in SW-Haiti in order to improve the
systematic, standardized inventory of those areas that are more susceptible
to earthquake ground motions or to earthquake related secondary effects such
as landslides, liquefaction, soil amplifications, compaction or even
tsunami-waves. Geophysical, topographical, geological data and satellite
images were collected, processed, and integrated into a spatial database
using Geoinformation Systems (GIS) and image processing techniques. The GIS
integrated evaluation of satellite imageries, of digital topographic data and
of various open-source geodata can contribute to the acquisition of those
specific tectonic, geomorphologic/topographic settings influencing local site
conditions in Haiti and, thus, to a first data base stock. Using the weighted
overlay techniques in GIS susceptibility maps were produced indicating areas
where causal factors influencing surface-near earthquake shock occur
aggregated and interfering each other and, thus, rise the susceptibility to
soil amplification. This approach was used as well to create landslide and
flooding susceptibility maps. |
