The water tank was damaged by the Kumamoto earthquake. The author's group has conducted a field survey. According to various reports, SUS tanks were damaged even in the latest designs after the 1995 Hyogoken-Nanbu Earthquake. The cause of the damage here is thought to be mainly due to the sloshing phenomenon and the bulging phenomenon. In 2012, the authors focused on the sloshing phenomenon in response to the 2011 Great East Japan Earthquake, and conducted vibration tests on actual SUS tanks. In this paper, the damage investigation of the SUS tank in the Kumamoto earthquake is shown. Also review the strain data of the vibration experiment. The result is compared with the damage of the SUS tank.
