Hirotane, Yu
This article identifies the actual state of the earthquake measures in the eighth century. Before the Taika Reform, as the feature of the earthquake measures before enforcing so-called Ritsuryo nationwide, it could be listed up the religious ceremony of “God of earthquake” based on an ancient nature of God faith. It was recognized that God faith and disasters brought closer together among those who at the time. In the Tenmu period, along with forming the political system of a state, the circumstances of damage had been described in detail through reporting from each local government to the central government. The earthquake damage information system centered by the government was established through developing the local government system. The establishment of Ritsuryo state that the government aimed was completed with Ritsuryo enactment in Taiho 1 (701). The government management was conducted by adapting regulation in various situations of administrative affairs and policy planning as well as the earthquake measures. Under the Ritsuryo state, the earthquakes were significant matters to send Chieki(馳駅) and there was also a comprehensive regulation to adequate earthquake damage. In addition, through Tenpyo 6 earthquakes in not only “Shokunihongi (続日本紀)” but also “Izumonokunikeikaicho (出雲国計会帳)”, the central government and each local government brought closer together by the system of“Kenshi(遣使)” and“ I(移)” and it had been identified that they dealt with earthquakes.
