Shift that occurred during the Northern Izu Earthquake, underground structure of the fault, three-dimensional model of the Tanna Fault

The shift of the fault that occurred during the Northern Izu Earthquake of 1930 is preserved in the Fault Park.

Here visitors can observe with their own eyes that as a result of a left-lateral fault movement, the waterway of the time shifted about 2 meters along the fault. Visitors can also see the rupture of the strata in the observation facility offering the viewer a very real demonstration of the fault movement.
