Fossa Magna
Great rift lowland in Japan / From Wikipedia, the free encyclopedia
Fossa Magna is a great rift lowland in Japan.[1][2] It is often confused with the Itoigawa-Shizuoka Tectonic Line. However, Itoigawa-Shizuoka Tectonic Line is a line; Fossa Magna is an area. Fossa Magna is Latin for "great crevasse".[3] This name was given by Heinrich Edmund Naumann.[4]
