Some relationships between intensity of hazardous natural events and amount of disaster damage

Regression equations which relate the amount of damage to the intensity of hazardous natural events are derived using statistical data of damages due to typhoon, flood, storm surge, landslide, earthquake and tsunami. Amounts of damages, especially casualties, are affected by such factors as locality, time, period, hazard type and so on. Regression coefficients and constants show quantitatively the effects of these factors on the amounts of damages. As physical indices to represent the intensity of natural events, radius of typhoon circle, central atmospheric pressure, maximum discharge, rainfall intensity, submerged depth, seismic scale, wave height etc. are considered. The relations may be used for damage prediction
