SUBJECT: CTBTO:  Update on DPRK Alleged Nuclear Test as of 27 May 
2009 
 
1. Please see para six for guidance requests. 
 
2. The Chair of the Preparatory Commission of the Comprehensive 
Nuclear Test Ban Treaty Organization (CTBTO) convened a meeting of 
the Preparatory Commission May 26 to discuss the claimed DPRK 
nuclear test.  All delegations that spoke were strongly critical of 
the DPRK.  For the most part, delegations used language from 
statements already issued by their Foreign Ministers or heads of 
state.  The Australian Preparatory Commission will now issue a 
summary of the statements. 
 
3.  The Provisional Technical Secretariat (PTS) of the CTBTO also 
provided a brief technical update on their preliminary findings. 
Atmospheric modeling was still under way, but the PTS continued to 
hope that radioactive debris would reach either the radionuclide 
station at Ussuriysk in Russia, or the Takasaki station in Japan, in 
a short time.  The noble gas systems at both stations are currently 
operational. 
 
4.  The PTS further announced that preliminary analysis of the 
seismic data showed the possibility of two near-simultaneous events, 
most likely an explosion triggering tremors in the region. 
Unusually in this case,the tremors could have been stronger than the 
explosion, thus increasing the apparent magnitude of the explosion. 
The PTS cautioned that their analysis is still very preliminary. 
The Reviewed Event Bulletin (REB) is due out early Thursday morning, 
May 28, and the REB should contain more detailed analysis of the 
seismic event. 
 
5. Comments:  Thus far, the International Monitoring System has 
performed well, keeping to its prescribed reporting timeline.  The 
2006 DPRK test was picked up by only thirteen seismic stations, so 
the fact the 39 stations reported on the event this week is a 
significant improvement, reflecting an increase in the number of 
stations and upgrades in the seismic arrays at other stations. 
Attention will now shift to the noble gas systems.  The most 
significant development since 200t is the increase in the number of 
radionuclide stations with noble gas systems in the immediate 
neighborhood of the DPRK.  Only ten of the projected forty noble gas 
systems had been constructed in 2006.  There are now twenty stations 
providing data on noble gas, and all systems should be constructed 
by 2013.  Station RN 58 close to the DPRK border at Ussuriysk, 
Russian Federation, is particularly important, since it has recently 
been equipped with a noble gas system. 
 
6. Action request:  the PTS reports several countries have shared 
information from their national systems with the PTS.  the PTS has 
asked for information for the United States as well.  Mission 
requests consideration of providing relevant information to the PTS 
concerning the DPRK alleged test.  We have also had requests from 
the UK and France to convene a P5 meeting at the working level in 
Vienna to discuss the DPRK event.  Mission requests guidance on such 
a meeting as well.
