Saitama Prefecture 地震風險
Saitama is part of the greater Tokyo Metropolitan area and would be heavily affected by a Tokyo Metropolitan Earthquake (M7.3 scenario). Southern Saitama's alluvial plain is particularly susceptible to liquefaction. The 30-year probability of a Tokyo Metropolitan Earthquake stands at 70%.
主要斷層・地震帶
Saitama's southern zone sits on broad Kanto Plain alluvium, making it prone to seismic amplification and liquefaction. A Tokyo Metropolitan Earthquake (M7.3 scenario) is expected to produce Intensity 6- to 6+ across southern Saitama. Minor fault lines have been identified beneath Saitama City itself.
