Hope all friends and family are doing well, hope there is no loss of property.
Now, this specially for those who do not know the causes of earthquake (so this post in layman language!) and are pro – development (at the cost of environment).
Well, we all do remember our geography lessons that earthquake is an effect of cause of internal disturbances, faults etc. BUT
What we probably didn’t study or is rather a recent find is .. there is something called Induced Seismicity
How is Japan earthquake different from Indian subcontinent’s Earthquake?
When an Earthquake hits Japan, it does hit headline but is not such a big surprise as we all know Japanese archipelago has a locational disadvantage (it is located in an area where several & continental plates meet & with continous movements of these plates causes disturbances resulting into both volcanoes & earthquakes). Without going into too much technicalities lets move ahead
Now, why is it such a surprise when Earthquake hits Indian subcontinent, because we don’t have any such locational disadvantage. But we forgot to take into account the RESERVIOR INDUCED SEISMICITY which is nothing but when a large dams which store water for multipurposes create a pressure on earth which leads to internal disturbances causing Earthquakes.
With this, I would like to sum up my article as I promised to keep it as simple as it could be.
Well, I am in a favor of development too but not at the cost of human lives … well it is yet too early to say that this earthquake too has been because of some reservior induced seismicity but the past data records do have a reason for us to belive in it

1. Reservoirs are believed to have induced five out of the nine earthquakes on the Indian peninsula in the 1980s which were strong enough to cause damage.
2. Major earthquakes had occurred at four large reservoirs; at Hsinfengkiang in China in 1962, (magnitude 6.1); at Kariba, in Rhodesia in 1963 (magnitude 5.8); at Kremasta in Greece in 1966 (magnitude 6.3); and at Koyna, in India in 1967 (magnitude 6.5)
