The Moon’s distance from our Earth varies each month between approximately 222,000 mi and 252,000 mi, due to its elliptical orbit.
Last Saturday night was Super Perigee Moon night, a full or new moon that coincides with a close approach by the Moon to the Earth. In short, Earth, Moon and Sun are all in a line, with Moon in its nearest approach to Earth. The last full moon so big and close to Earth occurred in March 1993.

Some are of the opinion that within ±3 days of a supermoon, the Earth is more subject to natural disasters such as earthquakes and volcanic activity due to the Moon’s increased gravitational force. However, according to Wikipedia, no evidence has been found of any correlation with major earthquakes. Last week’s terrible earthquake and tsunami in Japan is the only earthquake of 8.0 magnitude or greater to have occurred within 2 weeks of the 14 extreme supermoons from 1900 to the present date, suggesting that the claim of a supermoon effect on the incidence of large-scale earthquakes is unjustified.
