The Japanese and South Korean media have asserted that the DPRK is potentially preparing for a third nuclear test. I have no idea if this is the case, but the North Koreans certainly want us to see them conducting activities at their test site in Kilju county. Below I have placed some pictures of the area from both Google Earth and Digital Globe (taken at different dates) of the test site:
