Full Moon could have triggered December 26 Tsunami

Earth News: Indian Ocean Tsunami

October 27, 2006

LONDON: Everybody knows that the December 26 Indian Ocean tsunami was triggered by a massive undersea earthquake measuring 9.3 on the Richter, but what triggered the earthquake?Well, according to a new study, a full moon might have been the reason.Robin Crockett from the University of Northampton, UK, and his colleagues monitored tremors and collected tidal data along the Java/Sumatra trench, between October 2004 and August 2005.They found that major quakes were 86 per cent more likely around new and full moons, when tides are at their greatest.“At new and full moons the biggest mass of water is being loaded and unloaded at the plate boundary. That might be the final push that initiates a quake,” New Scientist quoted Crockett as saying.The study carries significance as Prof. Sebastian Hainzl from the University of Potsdam, Germany, and his colleagues recently found in another study that rain can also trigger quakes.They found that a rise in water pressure within porous rocks as rainwater soaks into the ground could start quakes on hair trigger faults.The water could ease the friction, releasing pent-up tension so that the rocks jerk past each other and initiate tremors as deep as four kilometres underground.
