Abstract
Mesh division of geographic model effects on results of run-up tsunami simulation. Recently, approximate accuracy ofgeographic models increase with using LIDAR (airborne laser). And run-up tsunami simulation using mesh of severalmeters came to be done. In this study, we study effects of mesh division on inundation area of run-up tsunami simulation.To exclude the effects of various conditions of the tsunami simulation, we designed the simplified probability calculationmodel. The calculation model determines the reaching probability of tsunami inundation area. As a result, the tendencythat inundation area of run-up tsunami simulation decreases as mesh size decrease was theoretically confirmed.
