A GIS based forecasting to earthquake damage of lifeline systems

Geological disaster reducing is one of the most important tools to keep the sustainable health development for whole socialites. This paper presents a GIS based performance assessment for lifeline systems earthquake damage reduction. The system could be used for seismic hazard assessment, lifeline earthquake damage and losses evaluation. The principle, design criteria, structure and functions of the system are described in this paper. The system is composed of four parts: information- and data-base, analytical modules, and a user interface. The information- and data-base consists of 68 coverages, including historical and instrumentally recorded earthquakes, seismotectonic zones, active faults, potential source areas, isoseismals of scenario earthquake, soil profiles, characteristics of all infrastructure systems such as: transportation network (roads and bridges, culverts), oil pipeline network, gas, water, electric-power, communication etc., distribution of citizens, rush-repair schemes of infrastructures and so on. There are also 28 analytical modules established in the system for generating isoseismals of scenario earthquake, site effects estimation, and damage and losses evaluation of lifeline systems. As an illustration, the operation of this system for reoccurrence of a historical earthquake is demonstrated.
