Tsunami Intensity and Disasters

Abstract

A tsunami intensity is defined as the logarithm of the local tsunami height to the base two. In terms of this tsunami intensity, important tsunami aspects are classified such as tsunami profiles near the shoreline, damage to individual houses made of wood, stone or reinforced concrete, damage percentage of wooden houses in a flooded area, damage percentage of fishing boats, damage to aquaculture rafts and effectiveness of tsunami control forests, based upon data from old documents of the past tsunamis.
