On March 19, the moon's orbit will make its closest approach to Earth in 18 years while at the same time be in full phase. Such a coincidence has been named a "SuperMoon" by Astrologers. The full moon of March will occur next Saturday on March 19, when the moon will be about 221,567 miles (356,577 kilometers) away from Earth. The average distance between the Earth and the moon is about 238.000 miles (382.900 km).
So the questions that emerge are: 1) Is there any legitimate science linking the Supermoon and extreme natural hazards? and, 2) Did the upcoming Supermoon play a role in this morning's horrific earthquake in Japan?

"The effects on Earth from a supermoon are minor, and according to the most detailed studies by terrestrial seismologists and volcanologists, the combination of the moon being at its closest to Earth in its orbit, and being in its 'full moon' configuration (relative to the Earth and sun), should not affect the internal energy balance of the Earth since there are lunar tides every day," Garvin wrote.
But while the moon helps drive Earth's tides, it is not capable of triggering devastating earthquakes.
"The Earth has stored a tremendous amount of internal energy within its thin outer shell or crust, and the small differences in the tidal forces exerted by the moon (and sun) are not enough to fundamentally overcome the much larger forces within the planet due to convection (and other aspects of the internal energy balance that drives plate tectonics)," Garvin explained.

There were SuperMoons in 1955, 1974, 1992 and 2005. These years had their share of extreme weather and other natural events. Is the Super Moon and these natural occurences a coincidence? Some would say yes; some would say no. I'm not here to pick sides and say I'm a believer or non-believer in subjects like this...
