项目摘要
In order to measure electric potential change associated with mining induced seismic events, we developed high-sensitive borehole antennas and installed them in a deep gold mine in South Africa in 2010. In addition, we installed borehole magnetometers which were newly developed in 2012. We evaluated the amplitude of electric potential change as a function of earthquake magnitude and source distance assuming rock contains randomly oriented quartz. Electromagnetic field changes were frequently observed when the seismic wave arrived. We discussed the waveformscomparing seismograms.
