SUPERMOON


The name SuperMoon was coined by astrologer Richard Nolle in 1979, defined as:
“ ...a new or full moon which occurs with the Moon at or near (within 90% of) its closest approach to Earth in a given orbit (perigee). In short, Earth, Moon and Sun are all in a line, with Moon in its nearest approach to Earth.”

The combined effect of the Sun and Moon on the Earth's oceans, the tide, is greatest when the Moon is new or full.
At lunar perigee the tidal force is even stronger resulting in more extreme high and low tides, but even at its most powerful this force is still considerably weak.

Speculations of a link between the occurrence of supermoons and natural disasters such as earthquakes and tsunami are extremely tenuous. Arguments have been made that natural disasters coinciding with years in which supermoons occurred were influenced by the Moon's increased gravitational strength, though because of the monthly alternation between lunar apogee and perigee such an argument cannot be supported unless the disaster in question falls on the actual date of the supermoon.

It has been argued that the Indian Ocean tsunami and earthquake on December 26, 2004, was influenced by a supermoon which occurred 2 weeks later on January 10, 2005.

Most recently, astrologers argued that the Tōhoku earthquake and tsunami that hit Japan on March 11, 2011, was influenced by the March 19 supermoon, the closest supermoon since 1992.
While some studies have reported a weak correlation between shallow, very low intensity earthquakes and lunar activity, there is no empirical evidence of any correlation with major earthquakes.
