Abstract: I here demonstrate empirically my georesonator concept in which tidally induced magnification of Earth masses' resonance causes seismicity. To that end, I show that all strong (~M6 earthquakes of 2010 occurred during the Earth's long (t>3 day) astronomical alignments within our solar system. I then show that the same holds true for all very strong (~M8 earthquakes of the decade of 2000s. Finally, the strongest (M8.6 earthquakes of the past century are shown to have occurred during the Earth's multiple long alignments, whereas half of the high-strongest (M9 ones occurred during the Full Moon. I used the comet C/2010 X1 (Elenin), as it has been adding to robustness in terms of very strong seismicity since 2007 (in terms of strongest seismicity: since 1965). The Elenin will continue intensifying the Earth's very strong seismicity until August-October, 2011. Approximate forecast of earthquakes based on my discoveries is feasible. This demonstration proves my hyperresonator concept, arrived at earlier as a mathematical-physical solution to the most general extension of the georesonator concept possible.
