Astronomers dismiss suggestion that sun and moon caused Japan earthquake

Reports that scientists had established a link between the activities of the sun and moon with the today’s Pacific tsunami have been dismissed by Irish astronomers.

THEORIES ABOUT WHAT might have caused the earthquake in Japan, which triggered a Pacific-wide tsunami, have abounded today.

One such theory, reported by Russia Today, claims that a link had been established between the activities of the sun and moon and the earthquake that occurred off the Japanese coast

Conor Farrell, manager of Astronomy Ireland, told TheJournal.ie that there was no truth in such a claim:

“The sun’s magnetic field can create northern lights, also known as aurora, that cause amazing light displays in the sky. These can potentially knock out communication satellites – although that’s not usual. The magnetic field wouldn’t have any effect on the Earth’s tides or trigger an earthquake”, he explained.

Farrell said that, later this month, the moon would display interesting activity and move closer to the Earth than it had come in many years. However, he stressed that while the moon does have an effect on the planet’s tides, this is separate to the seismic event that caused today’s tsunami in the Pacific ocean.

  • Hello all,

    I should clarify some of the mathematics and physics here.

    Today (the day of the Earthquake) the Moon’s distance from Earth is 393,502 km.

    Each month, the Moon reaches its perigee, i.e. its closest point to Earth. On average, this is 363,104 km distant. So, the Moon’s distance today is approximately 30,000 km further away than a point it reaches each month. Following from this, the gravitational force is also weaker than the average force it feels at perigee each month.

    So, today’s gravitational force would have no more effect on Earth than average – it would have had less of an effect, if anything.

    Secondly, the Moon reaches this month’s perigee on March 19th, over a week after the Earthquake happened. As the perigee is in the future, it’s highly unlikely to have influenced an event in its past. :)

    Clear skies!

  • According to Ben Goldacre on Twitter, the Daily Mail ran with this twaddle too. I expect the Daily Express are blaming immigrants or the ghost of Diana.

  • Japan is a Earthquake prone region, and the moon cannot be connected to each and every one of them. This time, the earthquake hit on a relatively shallow depth, and the epicentre was reported to be under the city. Which is a mere coincidence…lest Moon Deity had to punish them for some aabu-jabbu reason..:P…
    Am sorry Gentleman…no offences mean…am only producing how I think it is! Ain’t a cosmologist, an astronomer…neither a physicist…but one with a questioning mind…trying to find answers…

  • There is absolutely NO CHANCE that the moon can create enough pull to cause a Tectonic plate shift. Just think about it lads. To move the earths crust? Really? Would that not have had us all thrown about as well?

    • Sean. Everybody is missing my point. All I’m saying is that the earthquake might have been triggered AT THIS TIME by the slight increase in the moon’s gravitational pull. In other words, it was the final small influence in the cumulative process that was going to make it happen at some time soon, within a margin of maybe a year or so or who knows when. The straw that broke the camel’s back. The timing is the thing that I’m suggesting may have been influenced by the increase in proximity of the moon.

    Oh for feck sake, while we’re baseless theorys let’s go with another one I’ve seen on the net….it was caused by a US satalite which can cause earthqakes, oh wait that’s from a film!

  • Mr Farrell may have to eat his words yet. I’m not a cosmologist, an astronomer, a physicist or indeed an expert in any form of statistical predictive analysis but it seems to me that if the moon is coming closer to the earth, a larger gravitational pull from our nearest neighbour could be just the trigger that was necessary to cause the tectonic plates to finally shift. It may have been the straw that broke the camel’s back so to speak. I wouldn’t be so quick to dismiss the Russian scientists if I were him. How can he say that “there was no truth in such a claim”?

    • You said it: (you’re) not a cosmologist, an astronomer, a physicist or indeed an expert in any form – so lets leave the science to the experts. However just in case I’m going to tell my boss where to go, leavework early, go panic buying at my local Waitrose , do all the things I said I should do before i die, then going home and settling in for Gardener’s World.

      Godfrey, you say slight increase….do you even know just how slight your refering to?

      It’s as slight as weighing the titanic then placing a grain of rice on it and claiming the grain of rice can have a material impact on the performance and weight of the ship, the moon didn’t cause this.

  • The moon does affect the land masses of the earth, the moon is massive enough to have a gravitation pull on not only the surface of the oceans but on the continents too. The important thing to note is the moon is very far away and the internal forces generated by earth which do cause earthquakes and volcanic activity are much more powerful than the sight force of the moon and will only be affected fractionally. It’s also important to note the earthquake in Japan happened long before the moon reached perigee today (19th march).

  • The loss of life is a sad thing. The loss of life in Japan is tragic. The San Andeas fault. Scientists are waiting for the big one. Can this 8.9 earthquake in Japan trigger seismic activity on the San Andreas fault line? What about Yellowstone Park ? Is there any Scientist out there with the bare facts of the truth if why there is so much seismic activity ?

  • Scientists know that in the past seventy years there has been an exponential increase in seismic activity in earthquake prone regions. Something is wrong. Too many underground nuclear tests have cracked up the earth’s mantle. Expect more seismic activity, more earthquakes, more tsunamis, world wide food shortages, famines etc. The truth is out there. Scientist are not revealing all the truth . They are scared of things that will come to pass. May God have mercy on humanity.

    • Scientists know there is an increase in seismic activity over the last 70-years because the Richter Scale was developed when?? 1935. And that was what 75-years ago?? See the connection??
      Science has only been able to record and measure climate, seismic activity, plate movement, etc within the last 100-years or less. That is less than the blink of an eye in terms of earth’s existance. So, I wouldn’t bet the farm on what any scientist says because they still don’t know what they don’t know.

  • The tragedy of the Hiroshima and Nagasaki Nuclear Incident may have fractured tectonic plates in the earthquake prone region making it a targeted region for amplified seismic activity. the pressure build up had to release as the tectonic plates adjusted themselves raising the sea floor or ocean bed that triggered the 8.9 earthquake that resulted in the Tsunami striking Japan and other regions in the coastal areas.

    Look im not disagreeing or agreeing with anbody here but a few weeks ago we were told that on the 19th of mMarch this year that we would experience a “Super Moon”. They also said that when this happens that the Earth will experience some tidal effect and who’s not to say it could have an effect on the plates as well.

  • Newspapers have been recording earthquake incidents for 75 years ? 100 Years ? 150 years ? Anyone , anyone ?

    Any living person with five senses know that animals don’t need a Richter Scale developed in 1935 to know that an earthquake is about to happen.

    Animals by God -given instinct immediately know that an earthquake is about to strike before it strikes. How ?
    No Scientific Company gave the animals a gps system to predict when and where earthquakes will happen.

    QUOTE: “…ON THE morning of 26 December 2004, villagers from Bang Koey in Thailand noticed something strange. A herd of buffalo grazing on the beach lifted their heads, pricked their ears and looked out to sea, then turned and stampeded to the top of a nearby hill. For the baffled villagers who chose to follow them, it was a live-saving move. Minutes later, the tsunami struck.

    Since then, there have been hundreds of reports of animals seemingly foretelling the catastrophe – not just minutes, but sometimes hours and even days before it occurred. These include tales of bizarre behaviour across a menagerie of wild beasts including elephants, antelopes, bats, rats and flamingos, plus stories of dogs refusing to go for their usual morning walk along the beach. Could these creatures have been sensing early warning signs of the massive earthquake that triggered the Asian tsunami? It is an outlandish assertion, given …”.UNQUOTE.
