Figure 17From: Development of a borehole stress meter for studying earthquake predictions and rock mechanics, and stress seismograms of the 2011 Tohoku earthquake (M 9.0) Comparison of records obtained from the stress meter and the water pressure meter. For spring water at a distance of about 300 m away. A portion of the abrupt change in stress is superimposed on the pressure change curve to show the similarities.Back to article page
