据广泛报道，朝鲜于 2006 年 10 月 9 日世界标准时间 0135 点在吉州市西北约 40 公里处进行了核爆炸（图 1）。根据美国地质调查局国家地震信息中心（NEIC）快速确定震中（QED）中全球 31 个台站记录的地震信号确定的测试位置为北纬 41.294°，东经 129.094°，非常接近万塔山（万塔山，海拔 2205 米，见图 lc）。此外，自 20 世纪 90 年代末以来，监视卫星已检测到该地区的隧道活动，怀疑表明朝鲜准备在该地点进行核试验 [Broad 等，2005]。
North Korea carried out a widely reported nuclear explosion on 9 October 2006 at 0135 UTC at a location about 40 kilometers northwest of the city of Kilju (Figure 1). The location of the test determined from seismic signals recorded at 31 stations around the world was given as 41.294°N, 129.094°E in Quick Determination of Epicenters (QED) by the U.S. Geological Survey's National Earthquake Information Center (NEIC), very close to Mantap-san (Mount Mantap, 2205 meters, see Figure lc). Further, since the late 1990s, surveillance satellites have detected tunneling activity in this area suspected to be indicative of North Korea preparing to conduct nuclear tests at this site [Broad et al, 2005].
