Seismic data from North Korea suggest a repeat of the 2013 nuclear test

Lasrick writes: Seismologist Jeffrey Park has done an initial analysis of the seismic data from North Korea's reported nuclear weapon test and found 'an uncanny resemblance to the signals recorded for the February 12, 2013 detonation.' Park's analysis pretty much destroy's the North Korean claim that they detonated a hydrogen bomb, and he postulates that P'yongyang is desperate for attention during the US presidential election cycle.

Siegfried Hecker, one of the world's top experts on the North Korea nuclear program, is nonetheless concerned that the DPRK has now completed its fourth test, and with it a greater sophistication in their bomb design. Hecker is also skeptical that the test was an H-bomb. However, as he says, "We know so little about North Korea’s nuclear weapons design and test results that we cannot completely rule it out."
