A brief note on Earthquakes

While it is very commonly held notion that earthquakes are random and natural disasters, it is also possible that they can be triggered in an artificial way. I will explain you how, although in a trivial manner. Let us assume there is an event 'A' which generates an output variable say 'x', twice during the entire process. Once before the event has occurred and once after the event. And now, the possibility that the variable 'x' can somehow along with a few other variables could create the event 'A',should not be overlooked.
People who are taking 'Physics of Earthquakes' as their elective very well know that, a lot of cases have been documented showing the anomalous appearance of radio waves ranging from ELF to VHF, in the area of earthquake prone region, both before and after the earthquake has occurred. Now as I said earlier, we should not rule out the possibility of radio waves triggering an earthquake. Although, it is unknown, how a radio wave can trigger an earthquake which usually needs a great deal of energy?

Now, there are two possibilities, it could be that, a radio wave is causing an earthquake, or an earthquake is generating a radio wave! If we consider the first one, it could possibly be untrue as, earthquake is observed even in areas where you don't find a electromagnetic generated by humans.

We know that earthquakes only happen at places where there are faults and at plate boundaries. Due to natural movement of earth (i.e., rotation and revolution), the plate movement at equator is more rapid than at poles. Wait a minute ! ! Now, this could explain why earthquakes are less common at poles. And if you ask me why Japan and Chile experience more earthquakes, I will say this- they are near plate boundaries, particularly these two places are located near ring of fire which is an active chain of volcanoes and plate boundaries. Also earthquakes could happen at places where there are faults inside a plane which is more inhomogeneous. Also, I did not say that all places which have either plate boundaries or faults experience earthquakes! I said, it is possible for them to occur.
It entirely depends on whether there has been accumulated stress at a region and the possibility of the energy in that location being released at once.
Now, what could be the possible force that could release the accumulated stress?
And here, there are a lot of explanations. One possibility is the planetary forces. You can know more about that by Google by searching for "Planetary configuration-Implications filetype:pdf".
And in addition to that, the other possibilities includes the

• Sunspot formation
• Ionospheric disturbances  due to other factors
• Tidal waves etc.,

Whatever may be the prediction theory you choose, you end up with either radio i.e., electromagnetic waves or gravitational force.We can understand if I say that gravitational force can release the accumulated stress in fault locations, as it is a kind of physical force which we know that, can act on any body. EM force is not like that, I can show many objects that don't respond to EM energy or force, because they remain passive.
Are we missing something here??
What if the electromagnetic disturbances are getting transformed to gravitational force and triggering an earthquake. You may immediately say, that's impossible and ridiculous. Well! Wait.. Don't cross off the possibility. Studies are underway to find out the relation between two basic forces of nature as they have very important commons, like:

• Both EM and gravitational force travel with the speed of light
• Both forces' magnitude is inversely proportional to the square of distance between them

The GUT (Grand Unification Theory) exactly deals with this. It tries to unify the four basic forces in the universe, Strong Nuclear Force, Weak nuclear force, Gravitational force and EM force.
