Fujitsu’s collaboration with Touhoku University led to the development of a 3D tsunami simulator for high-precision tsunami forecasting.


The massive Touhoku earthquake of 2011 was one of the worst natural catastrophes that happened to Japan as of late. Not only did it cause major damage inland, but the tsunami that followed after the quake led to what is now infamously known as the Fukushima nuclear disaster.

Fujitsu, in wake of this tragic event, proposed a research project with Touhoku University the following year, in 2012. This research detailed the implementation of a new preventive measure that could significantly mitigate damage caused by such natural disasters. Two years later, Fujitsu finally announced today the development of a high-precision 3D tsunami simulator, which can be used to observe and predict potentially damaging major surges of water from various natural sources.

The 3D tsunami simulator can recreate how a tsunami flows inland in very accurate detail, showing the flow of water as it interacts with the general topography of the area it is going to affect. It can also simulate waves as it breaks and forms, and as it flows through obstacles like urban buildings and local coastal geographic features.

The current iteration of the 3D tsunami simulator is actually a combination of Fujitsu’s 3D fluid simulation technology and the previous 2D tsunami-propagation simulation system, which was developed by Touhoku University’s International Research Institute of Disaster Science. With the 2D tsunami-propagation simulation system, data processing loads are minimized due to its simplicity, while the 3D fluid technology allows accurate simulation of fluid flow due to the system treating the fluid as a collection of tiny particles.

Fujitsu and Touhoku University plans to incorporate the technology to various other innovative disaster prevention systems and technologies that are currently being developed and improved. With it, they hope that more advanced solutions can be made and taken, so that potential damage caused by future earthquakes and tsunamis can be significantly reduced.
