要約(英語): On March 11th in 2011, the power system suffered heavy damage from the huge earthquake and tsunami in Tohoku region. This paper describes the change of features including in the time series of the open demand data by the disaster 3/11/2011. The demand data is separated into three sections; one is for the `before disaster' analysis from April 2008 to February 2011, the second section is for the `while disaster' survey during March, April and May in 2011, and last data section is for the `after disaster' analysis from June 2011 to March 2013. We discriminated the periodical components of the daily, the weekly, and the seasonal fluctuation among the demand time series by applying newly developed procedure, the quasi-ideal moving average method. Some significant change were observed on the stochastic of the `before disaster' and the `after disaster' periodical components analysis. The change of the temperature sensitivity was also surveyed by using the open weather data in Sendai.
