2: The probability that an earthquake could occur within the next 30 years is based on the 2023 version of theNational Seismic Hazard Maps for Japan of the Headquarters for Earthquake Research Promotion of theJapanese government. The probability of a Great Kanto Earthquake is that of a magnitude 8 earthquake along
the Sagami Trough. The probability of an inland earthquake in Tokyo metropolitan area is that of a magnitude
7 earthquake to be caused by a sinking plate along the Sagami Trough.
