It occurred on the Atotsugawa Fault, which connects the Amō Pass in Gifu Prefecture (in the part that was called Hida Province) and Mount TateinToyama Prefecture (then known as Etchū Province) on the island of HonshūinJapan. Its name includes one kanji from Hida (飛騨国) and one from Etchū (越中国). The earthquake is estimated to have killed 200–300 people. It also caused the Mount Tonbi Landslide and blocked the upper reaches of the Jōganji River.[1]
