Mitsubishi Electric Develops Radar-Based Tsunami-flooding Prediction AI

Highly accurate predictions will support rapid evacuation planning

TOKYO--(BUSINESS WIRE)--Mitsubishi Electric Corporation (TOKYO:6503) announced today that the company has developed an artificial intelligence (AI) technology that uses data on a tsunami’s velocity detected by radar to forecast water inundation depths¹ in surrounding inland areas, working in collaboration with the Society for the Promotion of Construction Engineering of the General Incorporated Foundation. The AI incorporates Mitsubishi Electric’s Maisart^®2 AI technology to generate highly accurate predictions just seconds after a tsunami is detected, thereby supporting the rapid formulation of evacuation plans to prevent or mitigate disasters in local inland areas.

¹ Height of water level measured from the ground
² Mitsubishi Electric's AI creates the State-of-the-ART in technology.

Key Features

Maisart predicts inundation depth with high accuracy immediately after tsunami is detected

• AI learns the relationship between tsunami speed and inundation depths using simulations of various earthquake epicenters, degree and direction of fault displacements, and so on.
• The AI accurately predicts inundation depths with a margin of error of about 1 meter.³ The prediction is performed as soon as the tsunami’s speed and direction are detected with radar.
• Rapid prediction supports fast evacuation planning, helping to prevent or mitigate disasters.

³ Results of simulation evaluations using various test environments simulating possible earthquakes in the Nankai Trough
