38 North: Increased activity at North Korea's nuke test siteUpdated: 2014-05-01 21:57:24 KST
U.S. researchers say North Korea's nuclear test doesn't seem imminent at this point, that is IF the regime is sticking to its previous test practices.
Satellite imagery posted on 38 North, a website run by the U.S.-Korea Institute at Johns Hopkins University, shows vehicles and equipment are still outside a tunnel entrance at the Punggye-ri site.
In the past, all equipment, vehicles and personnel were withdrawn in the days before a test.
However, the website added there is no knowing whether North Korea is changing its procedures.
