Quite apart from the huge disparity in Richter values, the Indonesians and Indians were disturbed to find that the normal earthquake 'preamble' was missing from their seismograph charts. All this means is that the normal steadily increasing number of transverse shear "S" waves that always precede an earthquake were missing, as were later aftershocks, which likewise always accompany a naturally occurring or Tesla standing-wave generated earthquake. There were 'warnings' of aftershocks from the NOAA, but none actually eventuated.
