On November 14, the Moon was 14 percent bigger and 30 percent brighter than an average full moon. It was also the closest to Earth it’s been since January 1948. The Moon will get this close to us until 25 November 2034. In 2016, supermoons weren’t all that uncommon – we had one on October 16, and then on November 14, and we’ll have another one on December 14, joined by a meteor shower. So, here is a simple explanation of how do we get a supermoon…
“A supermoon is the coincidence of a full moon or a new moon with the closest approach the Moon makes to the Earth on its elliptical orbit, resulting in the largest apparent size of the lunar disk as seen from Earth.” “The full moon cycle is the period between alignments of the lunar perigee with the sun and the earth, which is about 13.9443 synodic months (about 411.8 days). Approximately every 14th full moon will be a supermoon. However, halfway through the cycle the full moon will be close to apogee, and the new moons immediately before and after can be supermoons. Thus there may be as many as three supermoons per full moon cycle.” The closest supermoon of the century will occur on December 6, 2052.
The influence of the Moon on both oceanic and crustal tides has led to claims that the supermoon may be associated with such events as earthquakes and volcanic eruptions. However, the scientists have proven that this effect is very slight. But there must be something else. The natural disasters, such as the 2011 Tōhoku earthquake and tsunami and the 2004 Indian Ocean earthquake and tsunami, are speculated to be linked with the 1–2 week period surrounding a supermoon. Also, I’m sure you’ve heard about the recent series of powerful earthquakes (one of which was of 7.5 magnitude), that jolted New Zealand, triggering a tsunami and sending aftershocks across the country.
