The "P" and" S" markers indicate a time of definite ULF activity 116 minutes prior to the event. Please note the amplitude as shown on the left side of the graph. The precursor activity was detected 14866 kilometers distant from the receive site and shows a low amplitude. Other sites closer to the fault location would show a much higher range of amplitude for the frequencies shown. |
