I am aware that ,by opening this blog and hypothesis ,I may be opening a big debate. I may not be able to prove it right now ,but this is a simple hypothesis based on observations
Earth moves with 23 and half degree NE declined. Moon maximum declination is 24 degrees North or South. Hence,23+24 =47 degrees North maximum declinaion. Similarly 23-24 =-1 degrees.This is because from maximum declinations Moon changes the declination and hence momemtum change in molten magma.
The maximum and major earthquakes occur at 37 to 57 degrees North as well as south(47+ or -10 degrees)(As tidal pull applies diagonlly it replicate at south also). Regarding -1 position ,the major and frequaent quakes occur at 9 degrees North to 11 degrees South(-1 + or -10 degrees)
These are just observations and no stats or mathematical calculations are done yet.
I believe,,this is the reason why we have potent and frequent quakes at these places
open for criticism
