A same base-line scale strain meter is also planned to be constructed parallely with LCGT. It will sense the ground motion such as tidal motion, regional trend motion, free oscillation of the Earth and so on. These data will be fedback and/or fed forward to keep the GW detector continuous locking. In advance of LCGT, some geophysical instruments were constructed or brought from other sites into the Kamioka mine. One of them is 100m strain meter that was set parallely with CLIO-GW. Another is a superconductive gravimeter (SG) that was brought from the Showa basecamp in Antarctica. Sometimes, an absolute gravimeter was also introduced to compare its data with that obtained from SG. The products of these instruments are summarized in the following file presented in GWADW 2008 Elba.
