The University of Science and Technology of China estimates the yield at around 12.2 kt, with a margin of error of 3.8 kt. Hence the max yield could be 16kT for this test.

Siegfried S. Hecker, former director of the Los Alamos National Laboratory, estimated yield at 15 to 25 kt Federal Institute for Geosciences and Natural Resources has initially estimated the yield as 25 kt The University of Science and Technology of China estimates the yield at around 17.8 kt, with a margin of error of 5.9 kt.

On 3 September, South Korea 's weather agency, the Korea Meteorological Administration, estimated that the nuclear blast yield of the presumed test was between 50 and 60 kilotons based on a magnitude 5.6 detection. South Korean Government 's initial yield estimate is 100 kt, and it detected a 5.7 magnitude earthquake, NORSAR Seismology Center initial estimate is 120 kt, based on a magnitude 5.8 tremor. On 12 Sept 2017, this was revised to an estimate of 250 kt based on a magnitude 6.1 instead. The German Federal Institute for Geosciences and Natural Resources estimate is `` a few hundred kt '', based on a 6.1 detected tremor. The Japan Meteorological Agency also detected a 6.1 magnitude tremor. from USGS : `` ( Magnitude ) 6.3 Explosion... Possible explosion, located near the site where North Korea has detonated nuclear explosions in the past. If this event was an explosion, the USGS National Earthquake Information Center can not 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. Paul Richards, nuclear seismic research scientist at Lamont - Doherty Earth Observatory said, `` The explosion appears to be the largest since China surprised the world with a magnitude 6.5 nuclear test in May 1992... The main point : this was a huge explosion, probably hundreds of kilotons, and larger than any of those conducted by the Soviet Union and the United States since 1976. '' He also said that `` Tentatively, I 'd put today 's test at around 250 kilotons with a factor of uncertainty around 2 until we get better information on the depth at which it was carried out '' Japanese Government : 160 kt U.S. Intelligence / Air Force Technical Applications Center : 70 to 280 kilotons. Earlier U.S. Intelligence had given an estimate of 140 kt with unspecified margin of error.

Jump up ^ Includes all tests with potential for nuclear fission or fusion explosion, including combat use, singleton tests, salvo tests, zero yield fails, safety experiments, and bombs incapacitated by accidents but still intended to be fired. It does not include hydronuclear and subcritical tests, and misfires of a device which was subsequently fired successfully. Jump up ^ Number of tests which would have been in violation of the Partial Test Ban Treaty of 1963, such as atmospheric, space or underwater tests. Some `` peaceful use '' cratering tests which should have been violations were protested, and later quietly dropped. Jump up ^ `` Small '' refers to a value greater than zero but less than 0.5 kt. Jump up ^ Some yields are described like `` < 20 kt '' ; such are scored at one half of the numeric amount, i.e., yield of 10k in this example. `` Unknown yield '' adds nothing to the total.
