Kanagawa Prefecture 地震風險
Kanagawa was the hardest-hit area in the 1923 Great Kanto Earthquake. The Sagami Trough — where the Philippine Sea Plate subducts — runs just south of the prefecture and has generated M8-class earthquakes on roughly a 200–400 year cycle. About 100 years have elapsed since 1923.
主要斷層・地震帶
The Sagami Trough runs beneath the sea south of Kanagawa, where the Philippine Sea Plate subducts beneath the Eurasian and North American plates. Both the 1923 Great Kanto Earthquake (M7.9) and the 1703 Genroku Kanto Earthquake (M8.2) originated here. M8-class events have recurred on roughly a 200–400 year cycle. Coastal reclaimed land in Yokohama and Kawasaki faces high liquefaction risk.
