RUSSIAN JOURNAL OF EARTH SCIENCES, VOL. 13, ES1002, doi:10.2205/2013ES000527, 2013 Figure 1. Graphs of variations of RMS values of EMR and GAE for different boreholes, typical for seismically calm periods: (a) and (b) – daily RMS variations, typical for Borehole G-1: (a) – RMS variations of EMR, (b) – RMS variations of GAE (the vertical component); filtering by one-third octave filter with central frequency of 150 Hz; average interval of 5 min. (c) and (d) – daily RMS variations, typical for Borehole K-33: (c) – RMS variations of EMR, (d) – RMS variations of GAE (the vertical component); filtering by high-pass filter at cutoff frequency of 150 Hz (see the text).
