It was discovered on October 24 that there exists an active fault line in the undersea section of the construction zone for the Henoko Base in Nago.
In the “Map of the undersea section” figure, part of the data collected by the “Alternative Facilities Construction Committee” formed by the Ministry of Defense in 2000, there is a depression on the map in an area close to 50 meters in length.
Dr. Yuzo Kato, professor emeritus at the University of the Ryukyus (specializing in petrology), said, “If the depression was formed in a relatively recent era, there is a chance that the seafloor fault line can grow larger.”
Already, on the island portion of the area plotted out for the new base, there is the “Henoko Fault,” and the “Sukku Fault.”
The continuation of these faults extend to a steep valley and incline on the seafloor.
Furthermore, the depression disclosed by the Ministry of Defense is overlapping. The fault appears to show evidence of earthquakes in the past, meaning that as an active fault there is a good probability of earthquakes in the future, casting doubt on the suitability of the location for a military base.
October 25 is also the six-month anniversary of the start of seawall construction.
