1945 Mikawa earthquake

As it occurred during World War II, information about the disaster was censored.

The city of Tsu recorded a magnitude of 6 on the Richter Scale; however, areas in southern Aichi prefecture were closer to the epicenter and suffered significant damage.

The earthquake created the Fukozu Fault, named after the village in the middle of the fault trace, in an area adjoining the west of the Tōkaidō Main Line railway between Okazaki and Gamagōri, Aichi Prefecture.

The fault's total visible distance is little more than 9 km, but is of great interest to geologists as it has a right-angle bend in its middle part, rather than being straight or at a gentle curve.

It is also remarkable in that ground displacement at the fault is up to one meter in places; however, the Tokaido Railway Line, although only 150 meters from the fault line in places, suffered no damage.
