This type of splitting is associated with the cracks in the crust aligned by stress. The origin of earthquakes due to the interaction of nociception waves with the gravity waves is critically investigated. The earthquakes of 8 Richter occurs only when the resonant frequency is extremely high. Low frequency resonances lead to earthquakes of 0.1 to 0.2 Richter. Low frequency resonances are hardly felt or realized by common man.
Accoustic anisotropy leads to very strong anisotropic stress on a rock.
Accoustic anisotrophy is found to be related with the stress history of rocks. This paper makes a serious study of the globality of the problem of earthquakes. As EPWs travel to great distances with time, abattoirs of one country may lead to havoc in other country. Interaction of EPW with the terrestrial waves does not recognize the political or man-made demarcation lines. We show that mistakes committed in certain nations have led devastating earthqaukes in other nations.
