You may wish to examine the effect on the seismograms of the geomagnetic
storm which hit at 13:23 - those showing the greatest effects were anti-solar -
at the South Pole, VNDA, Yakutsk and So. Karori, New Zealand. Also note
that the two seismograms from China went off line at the moment the storm hit.
