North Korea can conduct nuke tests 'with little or no warning': 38 North

38노스, "북한 사전징후 없이 추가 핵실험 가능 North Korea now has the capability to conduct nuclear tests without exhibiting any signs of test preparations. U.S.-based North Korea monitoring site 38 North says... the North appears to have altered its test preparation practices in order to make them more difficult to detect,... as demonstrated by its fourth nuclear test last month. The site says previous images suggest Pyongyang may already have finished digging several underground tunnels at its main nuclear test site in Punggye-ri ,... which would allow them to conduct another test "with little or no warning."
