From Pajamas Media:The data on the May 25th blast points to yet another "fizzle" of a bomb test by the North Koreans.
On May 25, North Korea detonated another nuclear device. The MSM claimed that the blast equaled the Hiroshima or Nagasaki bomb. Many worried that nuclear war with Korea was imminent. Russia put its troops in the Far East on alert.
Relax. The latest North Korean nuke was a dud, just like the one they exploded on October 9, 2006.
A nuclear bomb tested underground resembles an earthquake in many ways, and the yield of the nuclear explosion can be determined by the magnitude of the quake on the Richter scale. The MSM reports were based on Russian seismic stations, and these usually report higher magnitude than other observers. I always wait for the report of the Comprehensive Nuclear Test-Ban Treaty Organization, which includes not only the Russian data, but also the observations of earthquake observatories throughout the world — 61 seismic stations recorded the latest North Korean blast. Since the CTBTO combines all the world’s observations, it is the most reliable source of nuclear blast magnitudes.

My Comment: They will get it right eventually .... but these tests are done more to make a psychological and political point .... both here and abroad.
And the North Koreans have (so far) been successful at making their point across.
