The Punggye-ri site images where nuclear tests were conducted in 2006 and 2009 reveal that over the past month roads have been kept clear of snow and that North Koreans may have been sealing the tunnel into a mountainside where a nuclear device would be detonated. But it remains difficult to discern North Korea's true intentions as a test would be conducted underground, according to Fox

New satellite imagery from 23 January 2013 and previous images dating back a month reveal that the site appears to be at a continued state of readiness that would allow the North to move forward with a test in a few weeks or less once the leadership in Pyongyang gives the order, according to NTI
Last year, South Korea's Yonhap agency reported new excavation work at the Punggye-ri site, where North Korea had been believed to have tested nuclear devices in 2006 and 2009. South Korea's National Intelligence Service observed that earth and sand had been piling up outside a tunnel entrance at the site. Their analysts believe that the excavation was preparation for a third nuclear test, according to global security
The most recent commercial images of the Punggye-ri site where previous nuclear tests were conducted reveal that over the past month roads have been kept clear of snow and that North Koreans may be sealing the tunnel into a mountainside where a nuclear device would be detonated. But it remains difficult to discern North Korea's true intentions because any future test would be conducted underground. When we read about North Korea and its nuclear weapons, we see that it plans a surprise attack on South Korea, while threatening America with a nuclear response if the US choices to intervene in the conflict. North Korea stated it is building the missiles and nuclear weapons to destroy America because it plans on establishing the principles of deterrence after it attacks the South.
