Mitsubishi Electric Develops Radar-Based Tsunami-flooding Prediction AI

1 Mins read

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.

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.
