Can Planetary Alignment trigger an earthquake?
We have seen the destructive power of nature and it which earthquake is like its Achilles heel for earth. Earthquake cannot be predicted , their presence can only be found just before the quake by the means of Pre-quakes. This time span is not enougn for any country for evacuation.
There have been many theories which have been put forwarded my many geologists and Astronomers. Some of them are quite bizarre , but who gives a rat-ass about it!!.
We have seen Solar Flare theory but the newest theory is Planetary Alignment Theory (PAT) actually its quite old but has come to the radar in just few years .
This theory is based on a universal principle that is “Principle Of Gravity”. This gravitational pull is between two bodies having mass m1 and m2 and are separated by distance ‘r’. Thus we know that .
Our Solar System is made of 8 planets. From these 8 planets planets like Earth, Jupiter, Saturn, Uranus and Neptune mostly matters because of their size. Grater the size grater will be the gravitational force as according to above equation.
For more information see this video. This video is posted on you tube on the channel named The barcaroller. This video is about the sun-jupiter-earth alignment on May 14th 2012.
But still this is just a theory there is no evidence that these alignments will affect our earths crust or mantle and trigger an earthquake. so you can still trust your earth below your shoes. But we still got a 6.2 earthquake in Chile and many 4 magnitude earthquakes in us pacific plate. Middle east and south asia also had 4 magnitude of multiple tremors.
