Fugaku Supercomputer Helps Better Predict Tsunami Damage

Fugaku, the world’s most powerful supercomputer, was used to develop a model for predicting flooding caused by tsunamis. This AI-based model can however run on a standard computer.

Health crisis requires, Fugaku, the most powerful supercomputer in the world has been working a lot lately on the Covid-19. But the teams that work with this Kobe-based racer are not forgetting other priorities. In Japan, one of the most active earthquake zones in the world, the development of reliable prediction systems for earthquakes, tsunamis and their effects is a vital issue.

No one has forgotten the terrible day of March 11, 2011, during which a magnitude 9 earthquake followed by a tsunami caused 20,000 deaths and the nuclear disaster in Fukushima. Thanks to supercomputer Fugaku, Japanese researchers have therefore developed a tool using artificial intelligence to predict flooding from a tsunami in near real time is likely to cause.

Strategic data since it will make it possible to anticipate the impact of these terrible waves on the surrounding infrastructures (buildings, roads, bridges, etc.) and to propose more relevant evacuation measures. The teams used Fugaku’s capabilities to generate training data for 20,000 tsunami scenarios and train AI. The tool thus developed can however run on a standard PC. It will suffice to give it information on the waves observed offshore for it to provide in a few seconds detailed predictions on how coastal areas should be impacted by the water.

The model was developed jointly by teams from Tohoku University, Tokyo University and Fujitsu Laboratories. It is of course intended to help improve the prevention of disasters caused by tsunamis in Japan but also internationally.
