Before I start I would just like to say that my heart goes out to all those affected by the earthquake in Japan today, and if thoughts mean anything,
then the amount of love and prayer for Japan should set it in good stead for recovery.
Realising the magtitude of today's earthquake, it reminded me of Chile (which incidently was a little over a year ago), and an article that came out
not long after, concerning the amount of land mass that was shifted purported to the possibility of the earths axis being effected, and generating a
shorter earth day ( allbeit a measurment which we just wouldn't notice).
The Feb. 27 magnitude 8.8 earthquake in Chile may have shortened the length of each Earth day.
JPL research scientist Richard Gross computed how Earth's rotation should have changed as a result of the Feb. 27 quake. Using a complex model, he
and fellow scientists came up with a preliminary calculation that the quake should have shortened the length of an Earth day by about 1.26
microseconds (a microsecond is one millionth of a second).
Perhaps more impressive is how much the quake shifted Earth's axis. Gross calculates the quake should have moved Earth's figure axis (the axis
about which Earth's mass is balanced) by 2.7 milliarcseconds (about 8 centimeters, or 3 inches). Earth’s figure axis is not the same as its
north-south axis; they are offset by about 10 meters (about 33 feet).
By comparison, Gross said the same model estimated the 2004 magnitude 9.1 Sumatran earthquake should have shortened the length of day by 6.8
microseconds and shifted Earth's axis by 2.32 milliarcseconds (about 7 centimeters, or 2.76 inches).
Gross said that even though the Chilean earthquake is much smaller than the Sumatran quake, it is predicted to have changed the position of the
figure axis by a bit more for two reasons. First, unlike the 2004 Sumatran earthquake, which was located near the equator, the 2010 Chilean earthquake
was located in Earth's mid-latitudes, which makes it more effective in shifting Earth's figure axis. Second, the fault responsible for the 2010
Chiliean earthquake dips into Earth at a slightly steeper angle than does the fault responsible for the 2004 Sumatran earthquake. This makes the Chile
fault more effective in moving Earth's mass vertically and hence more effective in shifting Earth's figure axis.
Gross said the Chile predictions will likely change as data on the quake are further refined.
Link to article here....Nasa Chile Earthquake axis affected?
With this in mind, and Japan being in mid lattitude, just as Chile is, I was wondering what the chances are of the earths axis again being affected ?
I appreciate in real terms it won't really make a lot of difference, but thought it was interesting info from last years quake, and wanted to open up
the lines of communication to see see what you guy's thought on the subject.
Love and light everybody
