ABSTRACT

Plausible parameters of the earthquake fault which caused the 1771 Great Meiwa Tsunami were re-estimated by comparing the result of the tsunami run-up height by the numerical simulation by Okinawa Prefectural Government and those by 1) run-up height derived from previous field works, and 2) a historical record describing the run-up height in Miyako District. The re-estimation shows that the length of the fault off Miyako and Yaeyama districts is 300 km or more. However, the slip of the fault is 20 m off Yaeyama and 8 - 14 m off Miyako.
