Yale professor analyzes seismic finds on DPRK announced nuclear test – Latest media coverage on CTBTO

The Bulletin of the Atomic Scientists publishes an early analysis by Jeffrey Park, professor of geology and geophysics at Yale University, entitled “A broader reading of seismic waves from North Korea

Professor Park finds that the seismic signal recorded in North Korea on February 12 is consistent with a successful test of a crude, Nagasaki-type bomb and assesses that ability to deploy nuclear-tipped missiles has not been demonstrated.

And he concludes: As a technical matter, we are ready to implement the Comprehensive Test Ban Treaty (CTBT) immediately, at a time when world politics includes only one nation still claiming to develop new nuclear weapons. We should seize this chance now.

Latest media coverage on CTBTO

Chris Schneidmiller on Global Security Newswire has published a post titled “Nuke Trial, Meteorite Highlight Test Ban Treaty Capabilities”. On the 12 February DPRK event, CTBTO Executive Secretary Tibor Tóth is quoted referring to “a tragic opportunity to demonstrate the capabilities of the seismic” IMS stations, demonstrating that “the system is robust enough to alert the international community.”

Kyle Maxey in Engineering in a post under the title “Russian Meteor Makes Waves – Sound Waves“ asks the question: One could justifiably ask the CTBTO how, exactly, they knew the loud explosion in Russia was a meteor and not the start of World War III?

The article then provides the answer in the words of CTBTO’s infrasound analyst Pierrick Mialle: We know it’s not a fixed explosion because we can see the change in direction as the meteorite moves towards the earth. It’s not a single explosion, it’s burning, traveling faster than the speed of sound. That’s how we distinguish it from mining blasts or volcanic.
