  1. ^ To convert the UT time into standard local, add the number of hours in parentheses to the UT time; for local daylight saving time, add one additional hour. If the result is earlier than 00:00, add 24 hours and subtract 1 from the day; if it is 24:00 or later, subtract 24 hours and add 1 to the day. North Korea changed from UTC+9 hours to UTC+8:30 hours on 15 August 2015. All historical time zone data are derived from here:
  2. ^ Estimated energy yield in tons, kilotons, and megatons. A ton of TNT equivalent is defined as 4.184 gigajoules (1 gigacalorie).
  3. ^ Radioactive emission to the atmosphere aside from prompt neutrons, where known. The measured species is only iodine-131 if mentioned, otherwise it is all species. No entry means unknown, probably none if underground and "all" if not; otherwise notation for whether measured on the site only or off the site, where known, and the measured amount of radioactivity released.
  4. ^ Location from seismic data, about 6.4 km west northwest Punggye-ri and locus of previous tests.

Summary

North Korea's nuclear testing series summary
Series or years Years covered Tests Devices fired Devices with unknown yield Peaceful use tests Non-PTBT tests Yield range (kilotons) Total yield (kilotons) Notes
nuclear tests 2006–2017 6 6 0.7–250 197.8
Totals 2006-Oct-9 to 2017-Sep-3 6 6 0.7–250 197.8 (Based on average yield from lower to upper estimates as the Government of DPRK does not announce the exact yield.) Total country yield is 0.036% of all nuclear testing.
  1. ^ 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.
  2. ^ 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.
  3. ^ "Small" refers to a value greater than zero but less than 0.5 kt.
  4. ^ 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.
