NanTroSEIZE

CDEX developed a series of LTBMSs for the Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE). These were designed to measure, with high accuracy and precision, changes in downhole pressure, tilt, earth motion, and temperature. These are also used to observe earthquakes and tectonic motion, after being installed in riserless boreholes, some of which reach the megasplay fault. Riser borehole LTBMS are still under development.

Direct monitoring data of faults will help clarify the developmental processes and formation reactions proceeding or following huge earthquakes or provide realtime information when such earthquakes strike.
