The role of faults in studying the Sea of Japan lithosphere with the use of the Nakhodka-Naoetsu submarine cable

The paper analyzes the possible effect of conducting deep fault zones on th e results of sounding in the Sea of Japan with the use of the Nakhodka-Naoe tsu submarine cable. The analysis showed that the integral resistivity of t he lithosphere can be significantly underestimated if faults as wide as 20 km reach the asthenosphere, and the resistivity of their rocks is on the or der of 10 Omega m or less. If future, more realistic estimates show that th e faults are a few kilometers wide and their penetration depth is considera bly greater than the crustal thickness in the Sea of Japan, the fault effec t on the integral resistivity estimates can evidently be neglected.
