Figure 4. (a)  H(t) variation of the horizontal geomagnetic field component intensity for the FRN magnetic variation station (37.08oN; 240.28oE); (b)  dH(t) variations filtered from the H(t) data series in the period range of 32-128 minutes; (c) RMS A(t) variations of the total electron content of dI(t) in the period range of 32-128 minutes (bars); (d) same for the period range of 10-25 min, B(t); (e) same for the period ranges of 2-10 min, C(t). The bold curve plotted in (c) is the inverted H(t) curve smoothed using a 3-hour window. The letters A and B show the time intervals for which TEC variations recorded at Site AZU1 are shown in Figure 3. Given below is the local time scale LT for the 240oE longitude. The vertical bar marks the time of the main shock.
