Tono Geoscience Center (TGC) of Japan Atomic Energy Agency (JAEA) is being performed Mizunami Underground Research Laboratory (MIU) Project. The MIU Project is under the Construction phase (Phase II). One of the Phase II goals was set to develop and revise models of the geological environment using the investigation results obtained during excavation, and determine and assess changes in the geological environment in response to excavation. The hydro-pressure long term monitoring has been continued to achieve the Phase II goals. This document presents the results of the hydro-pressure long term monitoring from fiscal year 2005 to fiscal year 2008.
