抄録: Characteristics of damage caused by the Shimane-ken chubu Earthquake of 1978 are summarized as follows: 1) Since the magnitude of the earthquake was so small the damage to structures was slight. No dwelling fell down and no human lives were lost. The severest damage to structures was half collapse of four houses and several warehouses, small cracks in road pavement, and small scale landslides of cut slopes. This region is located in mountains and doesn't have thick alluvium deposits. Therefore, the ground motion of this earthquake was supposed to be mainly composed of short period waves. The maximum ground acceleration was estimated to exceed 300 gals in the survey of the narrow region of collapsed grave stones. 2) Most of the life-line systems such as roads, electric and water supply failed more easily than dwelling structures as has been common in past earthquakes. The damage to the function of the life line was especially remarkable in this earthquake because the damage to other structures was not serious. 3) The topographical effect on the damage was also clear, because the damaged area is mountainous.
