Anything Under The Sun

These past few months, mega earthquakes have been experience by countries that resulted to a great number of casualties. There’s the Haitian Earthquake, there’s the Chilean Earthquake, and some tremors were also reported in other part of the world. But can an earthquake have the capability to affect the Earth’s axis? The answer is yes. But not all mega earthquakes can influence the Earth’s rotation. That kind of earthquake that hit Chile recently can do the thing. Experts in NASA, as I have read in articles and news, Chilean earthquake has shortened the day for a milliarcsecond. This may not be that evident at all but it still cannot be denied that in some way or another can be a factor to another phenomenon that Earth might experience or have already experienced.

How can an earthquake like that in Chile has affected the Earth’s axis?

It has something to do with the weight that becomes heavier in the end or bottom part of the earth. This was due to the sliding of the earth’s plate that caused the earthquake. To make the concept easier to comprehend try doing this illustration:
Get a slingshot; put a light stone in it. Try to swing it in circular motion, and then observe the speed of the swinging. Now, this time try swinging the slingshot with a heavier stone. You will notice that the swinging is faster for the heavier stone compared with the lighter one. This has the same concept of how that earthquake in Chile had affected the Earth’s axis. Ooops, take note that not all tremors will do the same impact to the Earth’s rotation, else… hmmmn… it will be disastrous.
