????Two American scientists on 10th said that they pinpointing North Korea in May, 2009 underground nuclear test\’s place, had said the nuclear explosion central place is apart from the first nuclear test place about two kilometers.
????The Korean Yonhap News cite New York State University Stoney Brucker Branch school two scientist\’s papers to report, "US Geological prospecting" periodical formerly publicized the nuclear explosion central place error span is 3.8 kilometers, but these two scientists reduce this error to 140 meters.
????Two scientists published a paper saying in American "Seismic study Communication" January to February bimonthly issue, in last May North Korea implemented the second nuclear test nuclear explosion center occurred at north latitude 41 \’ 17 \’\’ 38.14 seconds, east longitude 129 \’ 4 \’\’ 55.21 seconds, “in 2006 north of the first nuclear test place 723 meters, west 2235 meters”.
????North Korea in October, 2006 implemented the first nuclear test in the Hamgyo\’ng Pukdo Jizhou county abundant brook. Afterward, the peripheral several national 9 inspection station monitors catch the nuclear explosion to cause the earthquake wave profile.
????Two American scientists said that they through the earthquake wave profile which studying the first nuclear explosion creates, understands the local complex geological condition, thus reduced to the second nuclear explosion localization error.
????“If North Korea will develop nuclear test from now on once more, when we can the pinpointing nuclear explosion place, these two scientists accept the Yonhap News reporter email interview immediately” said that “research nuclear explosion center place position as well as earthquake wave the influence which creates to the nearby geology, may determine the nuclear explosion equivalent weight.”
????“High accuracy positioning system may when nuclear test occurred, real-time provides the more accurate nuclear test infrastructure geographic network distribution map,” paper said. (Xinhua News Agency special news)
