Tämä superkuu olikin ihan uusi termi minulle. Hyvin järkeenkäypä ajatus se on, että jos uusikuu sattuu yhteen sen kanssa että Kuu on lähimmillään Maata, niin vuorovesivoimat ovat voimakkaampia ja täten todennäköisyys maanjäristyksille on suurempi.
Tällaisenkin sivun löysin superkuusta:
http://www.astropro.com/features/articles/supermoon/Lyhyesti suomeksi: Näitä superkuu-tilanteita on useita joka vuosi. Ilmiö on planeetanlaajuinen eikä siitä itsessään voi sen kummemmin tietää missä rytisee ja miten paljon. Yleensä siellä missä muutenkin on seismistä aktiivisuutta. Muilla tekniikoilla voi yrittää selvittää tarkemmin riskialueita.
referring to the date of the last SuperMoon as 18 years ago - as several media reports are doing lately - is completely wrong. There are 4-6 SuperMoons a year. The one on March 19, 2011 is in fact the closest SuperMoon of the year, but it's not by any means the first one in 18 years, nor even the first extreme SuperMoon in 18 years. The truth is, March 19 will be the second SuperMoon this year, and we only have to go back to January 30, 2010 to find the last example of an extreme SuperMoon
SuperMoon is a word I coined in a 1979 article for Dell Publishing Company's HOROSCOPE magazine, describing 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. In short, Earth, Moon and Sun are all in a line, with Moon in its nearest approach to Earth.
Obviously it won't be the case that all hell will break loose all over the world within a few days either side of the SuperMoons of 2011. For most of us, the geocosmic risk raised by SuperMoon alignments will pass with little notice in our immediate vicinity. In the grand scheme of things, we may live on a little blue marble in space; but it’s still a rather roomy planet, after all. A SuperMoon is planetary in scale, being a special alignment of Earth, Sun and Moon. By the same token, it’s planetary in scope, in the sense that there's no place on Earth not subject to the tidal force of the perigee-syzygy. Of course, earthquakes and volcanic eruptions don't go wandering all over the planet. They happen in (mostly) predictable locations, like the infamous "Ring of Fire" around the Pacific plate. If you're in (or plan to be in) a place that's subject to seismic upheaval during a SuperMoon stress window, it's not hard to figure out that being prepared to the extent that you can is not a bad idea. Likewise, people on the coast should be prepared for extreme tidal surges. Severe storms on the other hand can strike just about anywhere, so it behooves us all to be ready for rough weather when a SuperMoon alignment forms. Astro-locality mapping each SuperMoon can help indicate areas of special risk, but the whole planet is in the bull’s eye when one of these geocosmic shock windows opens up. Don’t be paranoid – but don’t be complacent, either.
