Lee Cheol-woo, a member of the intelligence committee of the South Korean National Assembly,
said his country’s National Intelligence Service had estimated that the explosive yield from the test
was equivalent to six kilotons of TNT. 6千吨
(By comparison, the atomic bomb dropped on Hiroshima in 1945 exploded with 15 kilotons of energy.)

A hydrogen bomb would have yielded “hundreds of kilotons or, even if it is a failed test, tens of kilotons,”
Mr. Lee told reporters. The North’s last nuclear test, in February 2013, set off a magnitude 4.9 tremor.
The South estimated that the bomb detonated on Wednesday resulted in a magnitude 4.8 seismic event,
smaller than the 4.9 to 5.2 range that American, European and Chinese authorities had reported.
