地震風險：very-high
Kumamoto Prefecture 地震風險
The 2016 Kumamoto earthquake (M7.3, 273 dead) struck from the Futakawa-Hinagu fault system. The sequence featured two Intensity 7 events — a M6.5 foreshock followed two days later by the M7.3 main shock — a first in JMA history. Mt. Aso volcano is also located in the prefecture.
主要斷層・地震帶
The Futakawa Fault Zone and Hinagu Fault Zone run east–west across Kumamoto Prefecture. The 2016 M7.3 earthquake resulted from coordinated rupture of these two faults. Mt. Aso (Aso-san) in central Kumamoto adds volcanic earthquake and eruption risk.
