South Korea’s weather agency, the
Korea Meteorological Administration, estimated that the
nuclear weapons blast yield of the presumed test was between 50 and 60 kilotons based on a magnitude 5.6 detection. •

If this event was an explosion, the USGS National Earthquake Information Center cannot determine its type, whether nuclear or any other possible type." Depth and lat/lon location approximate. • The
China Earthquake Administration also detected a 6.3 magnitude
earthquake. • The
University of Science and Technology of China estimated the yield at 108.1 ± 48.1 kt. • The
Geophysical Service of the Russian Academy of Sciences registered a 6.4 magnitude
earthquake. • The
Lamont–Doherty Earth Observatory estimated 250 kilotons. Earlier U.S. Intelligence had given an estimate of 140 kt with unspecified margin of error. • |- ==Summary==
