Beijing of China Newnorton internet antiviruss Service on June 19 rethe most popular north face shirtsport (reporter Sun Zifa) the rfree norton internet antiviruseporter learns 19 days from the the Chinese Academy of Sciences, this courtyard place belongs to a when university of Chinese science and technology finishs newest research, decided Korea accurately the position that subterranean nucleus exploded on Feburary 12, 2013 and equivalent.
Earthquake of university of Chinese science and technology watch casesand key laborbrass faucet aerator atory of earthly interior physics (in lab of division earth shake) Wen Lianxing teachs task group, the researchthe best spring pool that combines record of analytic seismometer observation and satellitic material makes clear, korea the nucleus exploded 20the most popular norton internet antivirus13 the center is located in north latitude 41 degrees of 17 minutes of 26.88 seconds, the east longitude 129 degrees 4 minutes of 34.68 seconds, fixed position error is 94 meters; This the nucleus explodes equivalent is 12.2 kiloton about, error 3.8 kiloton, its might is adjacent already the United States was in Japan 1945 the first atom bomb with overhand Hiroshima " little boy " (16 kiloton) .
On Feburary 12, 2013, korea in Xian Jingbei the nucleus was carried out the 3rd times to explode in brook of abundant of auspicious city county experiment. Subsequently, the earthquake of a few countries monitors periphery the station catchs this nucleus to explode the seismic wave that cause is undee, lab of division earth shake is in in explode to this nucleus for a short while undertake study. Before this, the nucleus that American geology investigates bureau and international to ban a nucleus to try an organization to announce explodes extent is the error of central position to be being lost 13.6 kilometers and losing 16.2 kilometers, and in the research with big family narrows this one error reach 94 meters.
norton internet antivirus" wall bulletin of earthly physics research " online recently the division in publishing studies this greatly achievement, the first author is the paper in Zhang Miao of graduate student of doctor of lab of division earth shake. Before this, scientific group explodes to Korea nucleus equivalent estimation also is put in great error, basically result from the nucleus explodethe most popular watch casess bury deepness decides hard. Lab of divi want modern dining chairsision earth shake is in on the foundation of exact location, used satellitic picture and tall Cheng data to decide Korea the bury deepness that the nucleus exploded 2013, computation its equivalent, and make estimation error contractible to 3.8 kiloton.
Group of division old research uses Korea in the nucleus exploded 2009 the seismic wave of generation is undee, eliminated the computational error that travels in earthly interior to seismic wave, the precision that the place before making fixed position is achieved did not see. So far, in the system of high accuracy location of lab of division earth shake decides Korharrison hot spring dealea accurately already from October 2006 all previous nucleus since first time nuclear tests explodes place, announced further nucleus of Korea abundant brook explodes the geographical network of infrastructure is distributed.
