In this paper, the technique using ship big data as a new technique for grasping a movement of tsunami was proposed. The ship big data is the accumulation data group of data about the cruise situation which is always sending, while a ship cruises, and grasp of the cruise situation of the ship of ocean area is attained in analysing them. As the application, as a result of analysing the ship big data at the time of tsunami on 11th March 2011, the drift ship group was discovered. Furthermore, as a result of analysing the details of this movement, it was thought that the motion was caused by tsunami. In order to prove this, the statistical method was used and qualitative evaluation was performed. As a result, it was confirmed the drift ship group was moved by tsunami. Thereby, it was clarified that the movement of a drift ship itself is the movement of tsunami itself.
