Shizuoka Prefecture 地震風險
Shizuoka is one of Japan's highest-risk prefectures for the Nankai Trough megaquake. The Tokai segment lies within the prefecture, and a 70–80% probability earthquake could send 10 m+ tsunami to Shizuoka's coast within minutes of rupture.
主要斷層・地震帶
The Itoigawa-Shizuoka Tectonic Line runs north–south through Shizuoka, forming Japan's geological east–west boundary. The Suruga Trough beneath Suruga Bay connects to the Nankai Trough. The Tokai segment has been designated a high-probability Nankai rupture zone; Shizuoka has Japan's most developed prefectural-level earthquake preparedness system.
