C0002G LTBMS Tiltmeter: Abnormal Values

Since 2:52:00 August 28, 2017 (JST), a tiltmeter installed in the IODP C0002G borehole (installation: December 2010, observation start: January 2013) has been providing constant values in X and Y components (X component: -13.899 micro radian, Y component: 4.510 micro radian). These values would be abnormal values, and probably be caused by internal problems of the tiltmeter. We are currently investigating reasons of this problem with manufacturer. If the situation changes, we will report on this website.
