[SCG58-P03] Large Scale High Precision Sand Box Experiments:
Precise Measurements of Precursory Signal Preceding to Frontal Thrust Formation
Keywords:precursor, earthquake, sandbox experiment
As a result, we obtained high reproducibility of the thrust formation including its position. With such a well-controlled experimental system, we found the precursory signal prior to thrust formation. In order to grab and understand the signal, we further improved the apparatus by installing the laser displacement sensor (resolution 0.1µm, span 800mm), a force sensor, and camera array for surface measurement. We will report the detailed information on the experimental apparatus our new findings.
