North Korea’s 2017 Nuclear Test Estimated to Be 16 Times Stronger Than the Bomb Dropped on Hiroshima
An updated estimate shows the September 2017 nuclear test by North Korea was equivalent to 250 kilotons of TNT-an explosive yield 16 times greater than the bomb dropped on Hiroshima during the Second World War. The explosion was also an order of magnitude stronger than the country's previous five tests.
