Abstract:

The ratio of collapsing houses by Tangshan earthquake was determined by sampling from aero photographies which were taken after shock. Analysis of mortality shows that the death percentage related to collapse of houses is more than 80%. Based on the fact that the death is mainly caused by collapse of houses, the regression curve of mortality and the ratio of collapsed houses by Tangshan earthquake is formulated. This curve can be used to rapidly estimate the death after shock by using the phase of damaged houses which can be surveyed from aero photographes.
