STUDY ON DEATH RATE OF CHI-CHI EARTHQUAKE

Chi-Chi Earthquake, occurred on the Chelungpu fault, caused many people deaths and injuries.This paper collected the casualty data in village and hamlet administrative units in the high intensity area, analyzed the relation between earthquake intensity and people death rate responding to three types of residential areas: city, town and village.It is obvious that the death rates in city and town type's areas are almost distributed in the same range while the death rates in village type areas are higher than them.The analysis of the relation between death rate and the factors such as the ground surface rupture distribution, the high intensity region and site conditions in local areas shown that the death rates with distance are asymmetrically distributed on both sides of the fault.These results make deeper cognition of the death rate distribution of Chi-Chi earthquake, and are significant for evaluation of casualty in the forthcoming earthquakes.
