Quake Changes Earth's Rotation, Moves Islands 917

kernel panic attack writes "This week's deadly Asian Quake and Tsunami may have been so powerful, that it changed the rate of Earth's rotation. In a Reuters article, a NASA geophysicist theorizes that the quake compacted the Earth enough to speed up the planet's rotation by 3 microseconds. A second article says the quake moved undersea tectonic plates by up to 98 feet, shifting islands near Sumatra out to sea an unknown distance. Also, a USGS team wants images from commercial satellite operators to help pinpoint coastline damage. Lastly, an interesting article from the Australian Spaceguard Survey about the need for a Tsunami warning system in the Indian Ocean. The author comments that tsunami warnings may not help much, as people often flock to the coastline to see the giant waves." The current estimated death toll is now nearly 70,000; Amazon and Google, among others, have added front-page links to simplify donating to the disaster relief effort.

        Private donatins and charity and campaigns like this are the kind of feel-good actions that do very little overall. They are usualy short-term campaigns tha collect a few millions than fade into obscurity within a week and bring little long term benefit.
        Fast forward a week or two. Amazon may have collected $5-10 million then everyone forgets about the whole deal. It's a perfect setup. Those that give a few bucks get the feeling that they contributed "enough", some people got some help, politicans can take the populistic "sure we are helping through private aid", the private NGOs get they paycheck and got the chance to help _some_ and off couse promote their agenda. And everyone in the western world is happy.

        So yes I think private charity like this is insignificant comapred to large initiatives, long term work and state based aid.

        So yes I do think Americans are stingy, together with the rest of the rich world. I know because I'm a stingy person myself on this area*. But then again I'm honest enough to admit it.

    I would not think a quake, even of this magnitude could have that much effect on rotation. Then again, the speculation is that there could never be enough energy for a 10.0 quake, so 9.0 is pretty high up on the list. It is impossible to comprehend, but an 8.6 earthquake has enough energy to equal 60,000 hydrogen bombs. Amazing.

        Thing is that stuff like this is really not out of the ordinary. This was the largest quake in 40 years, that means a larger one happened 40 years ago. And there were 3 larger ones in the past 100 years. Now for a human being once in every 40 years is rare, but for the planet that is pretty routine. We are all brought up to believe that the Earth is this fragile thing in which the slightest alteration screws up the balance of nature, but that really is not the case. It is a constantly changing giant rock spinning around in space.

        Now that doesn't mean that the quake can't have changes just because larger recent quakes didn't do anything. In fact we know that massive changes in the Earth have happened before in the more distant past, and I seriously doubt they were from SUVs polluting too much, so it is perfectly possible that there is something special about this quake (other than just its magnitude) that will cause major changes.

      Angular momentum is conserved and is calculated by L = Iw where I is the rotational inertia, w is the angular velocity and L is the constant product. So if I goes up (and I will show in a minute how that happens), w must go down.

      I, the rotational inertia, is calculated different ways for different geometries. A long stick held by the end has a larger I than the same stick held by the center, for instance. Another example is a sphere, like the Earth, rotating on an axis. If it suddenly puts out a long arm, that's going to increase its rotation inertia considerably, decreasing its angular velocity. Lifting up a whole region by a few inches could easily do that.

      Actually, the 3 microsecond effect (the Earth is now spinning a bit faster, shortening our day by about 3 microseconds) will have no long term effect. Our Moon has the drag effect on Earth anyway, continuously prolonging our days - about 15 microseconds per year.

      Aha, here is a bit about that from Wikipedia[1]:

      "The moment of inertia of Earth decreased a bit due to the earthquake. Because the angular momentum is conserved, this results in an increase of the angular velocity of Earth's rotation. In other words, the earthquake shortened the length of a day by as much as 3 s. However, due to tidal effects of the Moon, the Earth's rotation slows by 15 s per year. So any rotation speedup due to the earthquake will have no long-lasting effect at all."

      None. The second is defined relative to quantum levels in the caesium atom, that won't change. As for keeping up with the calendar, the Earth's rotation already has small variations; since 3 microseconds is roughly 1/300 second, we might have to subtract a leap second next July or December.

      Well, I'm writing this from Chennai/Madras which was hit quite badly (over 3000+ folks were killed from areas here and around).

      The problem is that this region has never seen Tsunamis before, and most people were just curious to see what the hell was happening. That made it only worse - a lot of them were morning walkers who were wondering what's up with the sea.

      If erudite urban folks are this naive, what can you expect off villagers? Actually, there is a story making the rounds of a guy from Singapore who called up his village and warned them about this, and they all moved to safety and nobody in the village was affected.

      The problem is that, it is not enough if you had a warning system -- you would need to know what to do with it. It's not sufficient to warn people, you need to tell them where to go and what to do, too.

    • The best prevention is education -- a scientist on a news channel in the U.S. yesterday said that when the sea recedes like it did before Sunday's tsunami, you have between 5-10 minutes to run the opposite direction. From most accounts, few did.

      Fsck, here went my moderation.

      I have been on that island (it is worth visiting while it lasts). Nearly killed myself aquaplaning in a tropical rainstorm on a road with 400+ meter cliff going into the sea on the right and 400+ cliff going up towards the volcano in question on the left.

      Anyway, on subject:

      It has a US Geological Survey run GPS station network every several hundred meters or so in some places do detect any movement and try to predict the next eruption. There will be a fair warning on this one. It is a question if anyone will dare to use that warning wisely which I doubt.

      That is the good bit.

      The bad bit is that compared to a worst case La Palma scenario the tsunami from 2004 Christmas earthquake will be a child's game in a puddle. The predicted worst case tsunami for La Palma is 800m at the start, 100+m at Marroco and Capo Verde, 30+m at Lisbon, Rio and the Caribean, 10+ m along the entire East Coast of the US including New York and Ireland and 5+ at the South coast of the UK. The death toll if there will be no evacuation will be in the tens of millions if not hundreds. That is the worst case scenario which is if it slides the same way it slid 1+ million years ago when the current north caldera has formed (it is the largest volcanic caldera formed by a landslide on the planet - 30km+ diameter). Even if it is a fraction of that it is still really scary.

      Just to make things worse is that current models are that a landslide is likely to follow one of the next 3-5 eruptions and it erupts every 20 years on average.

      And worst part is that it has not erupted for nearly 33 years now so the next eruption is likely to be bigger then usual.

This is not how The Earth is actually configured. For doing satelites one must models The Earth with micro-gravity elements, where masses are charted and denser areas have different effects based upon their sizes and locations. It is well known, for example, that under the South Atlantic Ocean there is a larger force of gravity.


      And so if there were a shift in some dense part of the mantle or the core where it went farther into The Earth (or farther away) it would change the rotational speed because of the conservation of angular momentum. Think of a child spinning on a swing. When the child pulls in his arms, the child spins faster. When the child puts her arms out, she spins slower. Same with The Earth.

I don't know the rates of average earthquake will speed up the earths rotation vs. the rate the gravitional effect of the moon slows the rotation.

At the same time, the moon gets 38 mm further from the Earth over the same period. This is a result of the two bodies being tidally locked (i.e., having synchronized rotations such that one side of the moon is always facing the Earth).

    Another estimate for the time change here.

    http://www.chicagotribune.com/news/local/chi-041 22 80221dec28,1,6119845.column

    (some useless registration required). I quote from the article.
    "Incredibly, the magnitude 9.0 earthquake that struck off Sumatra on Sunday morning caused a vertical displacement of so much material that the rotation period of the Earth has been permanently altered. By a tiny but measurable amount, the Earth is now rotating more quickly on its axis, and the 24-hour day is now one ten-thousandth second shorter.That's the result of calculations based on preliminary data made by Oak Park astronomer Dr. Leslie M. Golden. It's analogous to the increase in rotational speed that a twirling ice skater experiences when he or she draws in their arms. It is estimated that during the Sumatran quake, a block of material roughly 600 miles in length and 100 miles in width fell 30 feet closer to the Earth's axis of rotation. The planet has responded by rotating more rapidly, albeit ever so slightly, and our 24-hour days are now one ten-thousandth second shorter." by Tom Skilling.

    If it is one ten-thousandth of a second then it works out to have more effect.

    Doing the math for 1/10,000 of a sec/day:

    so 10,000 days = 1 second

    10000/365 = 27.39 years

    So in 27.39 years we loose a second.

    Diameter of earth 12,756 km or circumference 24,902 mi or 131,482,560 ft (appox at equator)

    One second of the day means a radial distance of

    24hr * 60 min *60 sec = 86400 seconds /day

    131,482,560 (feet / day) / 86400 (sec/day) = 1521.79 feet/sec

    at the equator (old 24 hour day)
    or is what the eath turns in one second

    or if there is change of 1521.79 feet of alignment in 27.39 years. or 55.56 feet / year.
    or:

    55.56 (feet/yr) * 12 in/foot = 666.72in/yr(bad omen here)

    or 666.72 (in/year) / 365 days (aprox) = 1.8 in /day difference.

    55.56 (feet /year) / 12 months = 4.63 (ft/month)

    This is a different estimate than Nasas but might be thought of as an upper bound until things
    can be calculated more precisely.

    Satelite's orbits will not change their period because of the change in the earths rotational speed. Geosynchronous satalites will slip out of synchronisity and need to use fuel to change their orbits, reducing their effective life as we have no way of replenishing fuel in geosynchronous orbit (around 22k miles out I think).

    This will be devistating for GPS and will require immediate upgrades/repossitioning to those systems.

    Can you imagine a year from now a precision guided missle landing 55 feet to the left. and each day
    an additional 55 feet more. Frightning. I image the military has stopped using GPS guided weapons
    until that can be corrected.

    Now if you correct those numbers for the Nasa estimate.

    3/100,000 instead of 1/10,000 then the

    or 3,000,000 days to get one second then.

    or 8219 years

    1521.79 (ft/sec) / 8319 (years/sec) =.1829 (ft/year) .1829 ft * 12 inches = 2.195 in/year

    much less of an adjustment or a threat to satelite's positions or positioning satelites.

    (check the math, who knows if I did it right)

    Just an intellectual exercise to assess the effect. Enjoy

    Normally when a person or entity uses the amazon honor system for donations/payments amazon takes a nice cut of the pie. I emailed them today to check if they did the same thing for the disaster relief and apparently they aren't!

    I included both emails below:

    TO: Amazon
    FROM: Urgo
    I have a question about the disaster relief donation page that you have setup on amazon.com. I know normally with the amazon honor system amazon gets a cut of all the donations. Is amazon taking a cut of the money in this case or is all of the money people donate going right to the red cross?

    FROM: Amazon
    TO: Urgo
    Thanks for writing to us at Amazon.com.

    Please rest assured that all the donated money will go to the Red Cross to help victims of tragedies in southern Asia, India, and Africa.

    Please know that Amazon.com is waiving its usual fees.

    Amazon and Google, among others, have added front-page links to simplify donating to the disaster relief effort.

    Perhaps Slashdot could do the same? After all, 80,000 dead and counting definately counds as "Stuff that matters."

    Why is it that so many people did not know that if the sea suddenly goes out very fast, it's going to come back again even faster.

    So if that ever happens to you, don't hang about, run inland as fast as your little legs will carry you. You life depends on it.

    Slashdot moderators please help get that message out, you will save lives.
