要約(英語): The 2011 off the Pacific coast of Tohoku Earthquake was a massive earthquake of magnitude of 9.0 occurred 11 March, and was long duration time. Though the electrical accident had been widely occurred in the Kanto region, the cause of occurrence was not easily understood concerning the short-circuit accident between transmission lines. In this paper, after understanding the fact of the event, simulation model of occurrence site was made and the event reproduction analyses were done to clarify the possibility of the event reproduction. In addition, the cause of the short-circuit was considered by using a seismic design standard related to gas piping targeting the Rayleigh wave and the long-period earthquake ground motion prediction map while thinking about countermeasures to short-circuit accident in the future.
