Scratch due to the earthquake, Quakes recorded on the torpedo

The surface displays physical marks and abrasions that demonstrate the force of seismic movements on geological formations during the 1930 earthquake.

The North Izu earthquake of November 26, 1930, with a magnitude of 7.3, created these permanent marks along the Tanna Fault system.

Japanese scientists and researchers examine these geological formations to understand the patterns of tectonic movements in the Izu Peninsula region.

The location provides direct evidence of seismic activity through visible scratch marks, making it valuable for geological education and research purposes.

These earthquake-induced scratches serve as a permanent natural recording device, documenting the precise movements of the earth during seismic events.
