Society is aging rapidly in Japan. For disaster mitigation against periodic earthquakes based on asperity theory in seismology, the transition of the social environment should be considered in the intervals between periodic events. This paper focuses on the aging of society as an important expansion factor in human injury. The major objective of this paper is to estimate the effects of aging on injury including serious cases caused by earthquakes. In this paper, three age classes are used as follows. Young age is defined as the generation under 14 years. Old age is defined as 65 years old or over. Middle age is defined as the other group. This classification is often used by the census. |
