The making of nuclear weapons might be the cause of the recent Japanese big earthquake, I guest something went wrong in one of those secrets nuclear weapon manufacturing compartments of theirs, which lead to this massive earthquake. I will not be surprise if the Japanese have a large secret deep underground military compartment extended to the whole Asian continent in Chinese back, by financing the poorer south east Asian and some unemployed Japanese to do the work for them. Actually, they could of easily do it since they are an technologically advanced country. Hey, if poorer North Korea can do it without been detected in South Korea backyard, so can big daddy Japan, Hahahahah!!
