Field investigation of the September 5, 2004 Tokaido-Oki Earthquake Tsunami

A large earthquake of Magnitude 7.4 was occurred off the coast of Tokaido. Although the epicenter was located along the Nankai Trough, this earthquake was not the Tou-Nankai earthquake which have been dreaded to occur in the impending future. A tsunami, however, was generated by the earthquake and arrived to the Pacific coast of the Kanto, Tokai, Kinki and Shikoku districts in Japan. Several research institutes carried out a joint field investigation in Tokyo, Shizuoka, Aichi, Mie, Wakayama and Tokushima prefectures. Therefore, there was not any human damages, but there were inundation in coastal areas, run-up along some rivers and capsize of many boats in the Kii Peninsula.
