Description

The objective of this study is to develop the convenient simulation system of the spreading fires at an earthquake. Generally, it requires a tremendous labor to make the data which are used for this kind of simulation. This system needs some attribute data and the coordinate of each residence which can be picked up with a digital residential map in a simple manner besides the data about the wind direction, wind velocity and seismic intensity. A work file is produced with the basic data and the simulation of the spreading fire is formulated as the shortest route problem, which is solved by the Dijkstra's algorithm. The results of the simulation can be shown on the digital residential map of computer display.
