For an efficient patrol to prevent and/or minimize secondary disaster such as fire breakout, diffusion of oil at the tank sites just after an earthquake, we have developed a system that can quickly estimate the extent of damage of tanks by liquid sloshing using earthquake early warning (EEW). The process flow of the system is (1) Evaluation of arrival time and seismic intensity using EEW, (2) Estimation of velocity response spectrum Sv using the semi-empirical method, (3) Evaluation of the possibility of oil overflow and of roof failure based on Sv, and (4) Transmission of the potential damage information to mobile telephones or to PCs by e-mail. Since the process time from (1) to (3) in the above process flow is within 0.4 sec, it is considered that the system provides useful information for the rational initial responses at tank sites.
