We create a hazard map of Route-to/from-School for stone masonry walls in Kure city based on an earthquake scenario in order to indicate the danger zone for the public. The seismic stability of the stone masonry walls is evaluated using DDA (Discontinuous Deformation Analysis), which is a type of discrete element method and suits to solve the large displacements accompanying the discontinuous movements between blocks. First, we survey the detail of the stone masonry walls along the Route-to/from-School and examine the accuracy for simplifying the analytical model. Then, we estimate the seismic stability and possible dispersed areas of the stones from the collapsed walls based on an earthquake scenarios. Finally, we create a hazard map of Route-to/from-School for stone masonry walls in Kure city.
