What is the really destabilizing and threating peace? Is some houses on land that really belongs to Israel or is it North Korea? North Korea continues to fire missles and explode things undergound around that area of the North Americia Tectonic Plate! That area is known for its earthquakes some has high as 8.6. How many tons of explosives are need to cause one of thoses plates to shift 30,60,100 and don't forget 1945 that could have caused a crack. Now with continued assault on the earth structure what next? How about an earthquake that removes islands. What about the Andres Fault Line[ fault line= Geology : the line of intersection of a Fault with The Earth's surface. What about the so called Big One? The earthquake in Japan was 12 miles bellow the surface so this is suppose to mean something. Things on the surface are frighting yes, but what cause them? Things done underground.
