I think geology,astrology give us some tips about earthquakes..For example;you can imagine earthquake movements that is lateral(from left to right or from right to left) and magma's movement also same..magma doesnt follow same orbit, not smooth so there is similarity between them..Another example;when Lunare eclipse happens after it most probably(not certain) eartquake borns..why not certain?because Moon,lots of planets have to be consecutively for earthquake...
