Satellite imagery of North Korea’s Punggye-ri Nuclear Test Site taken on March 28, and published by 38 North, shows a contingent of 70-100 people standing in formation in an administrative area. Such a gathering suggests a nuclear test may be imminent: as 38 North notes, it had not observed such a formation at the test venue seen since Jan. 4, 2013, shortly prior a nuclear test on Feb. 12 of that year.
