Along the Nankai Trough, M8 class earthquakes may occur consecutively. Among these two earthquakes, the earthquake occurring on the east side is called the Wide Tokai earthquake(WT), west side earthquake is called the Nankai earthquake(N) in this paper. This study was conducted to clarify the period during which the crude oil processing capacity is insufficient when the N occurs at an arbitrary time difference after the occurrence of the WT. After WT occurred, the reduced crude oil processing capacity was estimated during the period up to 365th day of N occurrence. In the case where the number of days when crude oil processing capacity is insufficient is the largest, N occurred on the 60th day after WT occurrence. In addition, it became clear that the case where the final day when crude oil processing capacity is insufficient becomes the latest will always be the day before the final day of the estimation period.
