Abstract
A killer earthquake with M7.3 would attack the metropolitan area in near future. This would result in 23,000 deaths (16,000 due to fires and 6,400 due to the building collapses and so on) and disorder of railroad traffic including Shinkansen and subways for one week, and Japan National railways and private companies ones for one month. On the other hand, Tokyo Olympic games will be held for two weeks in 2020. I discuss what kind of things will occur if the earthquake occurs just in time or before the Olympic games.
