1. Development of a geographic information system (GIS) for earthquake disaster data management is introduced. Based on the data from Nishinomiya City, results are presented on cross-cut analysis about the disaster of various urban facilities caused by the 1995 Hyogoken-Nambu earthquake, by using GIS. Correlation studies between building damage and lifeline damage, geology, ground failure and others should provide an important information for future disaster mitigation and preparedness studies.
2. The mobile data acquisition system is developed for building inspectors and/or researchers, who want to collect and update building damage data in post-earthquake reconnaissance. GPS (Global Positioning System) receiver provides positions and field information for GIS (Geographic Information System) functions. The system enables operators to easily navigate to features and to update GIS data when performing routine maintenance or inspections for buildings.
3. Recovery process of water and gas lifelines in the areas among Kobe and Nishinomiya cities, which were severely damaged in the Great Hanshin-Awaji Earthquake Disaster, is developed on GIS and is analyzed with each damage situation. Daily-life inconvenience of lifeline users is also compared with recovery states from lifeline supply-side, using questionnaire-sheet survey against JSCE members lived in the disaster areas.
