"The last "supermoon" this year was in effect Feb. 12-21, Nolle said, just before the earthquake that left Christchurch, New Zealand in ruins on Feb. 22, 2011.
Nolle also stated that the last extreme "supermoon" occurred on Jan. 30, 2010, several weeks after the catastrophic earthquake that hit Haiti on Jan. 12, 2010.
Paquette also pointed out in his blog that the devastating earthquake and tsunami that hit Indonesia on Dec. 26, 2004 occurred about two weeks prior to a "supermoon" on Jan. 10, 2005.
More natural disasters, such as Hurricane Katrina, are mentioned in conjunction with "supermoons" in Nolle's article."
