Did the Moon cause last week’s Earthquake?

Earthquakes, Tsunamis, SuperMoon… as humans we try our hardest to come up with reasons as to why things happen. In light of the events in Japan, many people are wondering if the Moon, or more appropriately the SuperMoon is to blame.

A SuperMoon is explained in great detail here, but basically it is a very large full Moon. A SuperMoon occurs when the Moon is at least 90% of the way to its perigee (closest approach to earth) position at the same time it is full or new.

With a SuperMoon coming up on Saturday, March 19, many people are wondering whether or not extreme SuperMoons can cause natural disasters such as earthquakes, volcanoes, and tsunamis. While we know that the Moon does have a direct relation on tides, most astronomers and scientists do not believe this SuperMoon had anything to do with the earthquake or tsunami that hit Japan last Friday.

Even though this particular full Moon is larger than normal and at its closest point to the Earth, it is unlikely to cause much disruption on Earth, beyond the usual proxigean spring tide. These tides are usually stronger when the Moon is new than when it’s full, so the conventional wisdom is that the upcoming event will result only in slightly higher than normal spring tides.

What do you think? Do you think the SuperMoon had any impact?  Share your thoughts here and remember, no matter what you believe about the SuperMoon’s impact on Earth, be sure to you check out the sky this coming Saturday night.

By the time I’m writing this, there was an earthquake yesterday at China, and also there was a Supermoon. I think it is more a “coincidence” but in the other hand I have my doubts. If the moon affects tides, because of the liquid mass of water in the oceans, it can also probably “creates” tides in the liquid mass of the inner parts of the Earth, like magma for example, causing an earthquake. I’m not a geologist.

does a full moon have any effect on a baby’s delivery?

The Japanese earthquakes were part of a 188 day cycle that some scientists have found where the Earth conjuncts the sun and a heavy mass object that entered the solar system in 2011. Can you track the heavy mass object and advise where it is currently? Every approx. 188 days we have a major destructive event. The super moon may have been another effect of this conjunction.

Algier the moon can’t cause earthquake tsunumis or disrupt the earth because the moon is so faraway from the earth right now

there were three full moons with in 28 days august 13th , august 28th, and sept. 12th i think thats why we had two earthquakes and a weird hurricane and flooding the week of the 28th but none of the calendars are showing a full moon for the 28th of agust . my friends and i saw it though i thought that was impossible?

We know that the moon has a direct effect on the tides. Tsunamis are a super tide. Super MoonSuper Tide. So Maybe.

I believe that it makes hi tides and has effect on the weather , people, gardens and such but not sure on earthquakes

If you notice a hole in the upper left-hand corner of your Farmers' Almanac, don't return it to the store! That hole isn't a defect; it's a part of history. Starting with the first edition of the Farmers' Almanac in 1818, readers used to nail holes into the corners to hang it up in their homes, barns, and outhouses (to provide both reading material and toilet paper). In 1910, the Almanac's publishers began pre-drilling holes in the corners to make it even easier for readers to keep all of that invaluable information (and paper) handy.
