Paper Number: SUT-OSIG-12-05
...1. Introduction With recent developments and application of geo- graphical information system (GIS) capabilities, geohazard assessments can benefit from detailed data integration. This facilitates the merging of dif- ferent datasets, such as 3D exploration seismic; high-resolution seismic (e.g...
