North Korea’s Nuclear Test: Another Fizzle?
The North Korean nuclear test on May 25, 2009, was “heard” loud and clear around the world despite its apparent limited size. Detection of small, clandestine nuclear tests seems to work. |

The Korean Central News Agency reportedly has announced that North Korea “successfully conducted one more underground nuclear test on May 25 as part of measures to bolster its nuclear deterrent for self-defense.” Several news media reported that the Russian Ministry of Defense estimating the test had a yield of approximately 10 to 20 kilotons.
Yet the preliminary seismic data published by the U.S. Geological Survey (USGS) shows that the test had a seismic magnitude of 4.7, only slightly more powerful than the 4.3 of the 2006 test.
Was it another fizzle? We’ll have to wait for more analysis of the seismic data, but so far the early news media reports about a “Hiroshima-size” nuclear explosion seem to be overblown.
Update: CTBTO’s initial findings.

A military depot in central Belarus has recently been upgraded with additional security perimeters and an access point that indicate it could be intended for housing Russian nuclear warheads for Belarus’ Russia-supplied Iskander missile launchers.
The Indian government announced yesterday that it had conducted the first flight test of its Agni-5 ballistic missile “with Multiple Independently Targetable Re-Entry Vehicle (MIRV) technology.
While many are rightly concerned about Russia’s development of new nuclear-capable systems, fears of substantial nuclear increase may be overblown.
Despite modernization of Russian nuclear forces and warnings about an increase of especially shorter-range non-strategic warheads, we do not yet see such an increase as far as open sources indicate.
