5. Further studies
We have been studying the integration of core measurements and borehole measurements to obtain a more advanced understanding of the physical and chemical processes within the fault zone. We are also planning repeated borehole experiments; such as hydraulic tests and trapped wave observation using borehole seismometers to see if we can observe any healing process of the Nojima fault after the 1995 Kobe earthquake.
