15 March 2011: On March 19, 2011 the Moon will pass by Earth at a distance of 356,577 kilometers - the closest pass in 18 years.


This is known as lunar perigee and a normal lunar perigee averaging a distance of 364,397 kilometers (226,425 miles) happens once every orbital period. The term "Supermoon" was coined by the astrologer Richard Nolle.



In short, Earth, Moon and Sun are all in a line, with Moon in its nearest approach to Earth.


The Supermoon occurred in 1955, 1974, 1992 and 2005 were amazing.


It is a scientific fact that when the Moon is at perigee there is more gravitational pull, creating higher tides or significant variations in high and low tides.


In addition, the tidal effect of the Sun’s gravitational field increases the Moon’s orbital eccentricity when the orbit’s major axis is aligned with the Sun-Earth vector.


The average tidal bulge closely follows the Moon in its orbit, and the Earth rotates under this tidal bulge in just over a day. Generally Tidal forces contribute to ocean currents, which moderate global temperatures by transporting heat energy toward the poles.


It has been suggested that in addition to other factors, harmonic beat variations in tidal forcing may contribute to climate changes.


From extreme coastal tides to severe storms to powerful earthquakes and volcanic eruptions, the entire natural world surges and spasms under the sway of the Supermoon alignment - within three days either way of the exact syzygy, as a general rule.


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.


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.


The Supermoon 2011 will mean that it will be brighter and larger in the sky than other full moons, but some believe that the super moon is connected to natural disasters.


Past super moons have been connected to the Indonesian earthquake in 2005 and a massive flood in Australia in Earthquakes, storms, intense tidal activity are some of the probable disasters that the impending ’Supermoon’ or lunar perigee may trigger.


The moon will look much larger than normal especially when it rises on the eastern horizon at sunset, or given the right atmospheric conditions. Some astronomers are predicting that the Lunar Perigee event coinciding with a Full Mean will affect climate patterns on Earth.

The third largest nuclear nation could not alter their destiny, save their junta from the claws of nature.(The fukushimaDaiiti nuke pwr plnt alone generates more pwr than all combined nunkes in India).there is no alternative in simple words live happily till death

As I recall the Moon in 1977 was 280000 miles away mean average now the Moon is 238000 miles away mean average My question is where did approximately 40000 miles of orbital distance go ? Commonly people recite a Lunar distance of 280000 miles is common knowledge at least in 1977 and 1978 ????>>>>

The supermoon combined with the extra energy from the solar flare today will cause a large earthquake within the next few days. Look like the San Andreas 8.1.

I wonder how much this gravitational shift has influenced the earthquakes and tsunamis we re seeing in Japan.

scared to dead!!! want to know what is going to happen on the 19th of march.

Guys don't worry. We are all geared up. It's nothing much. LET' S ROCK !!!!

Whether it is Lunar Perigee or Lunatic perigee, its quite a natural phenomena, we, the humanbeings, should be prepared to face it with all courage and precautions. When the end result of 2005 SuperMoon was so evident in the eastern coastal regions, when it is astronimically believed to happen on 9 March 2011, we should better equip ourselves and advice people in coastal regions to be prepared with an alternate plan now itself, instead of blindly believing that God will help and Government will rescue..

thanks for telling these facts to us and these are very scary and i also said that to the people of kurnool.that was nice

i think that nothing big is going 2 happen... cuz still it can t be surely said that the earth ll b destroyed on 19th march....
