The nuclear tests were performed in the Ras Koh hills in the Pakistani province of Balochistan.
Pakistan conducted its first series of true nuclear tests on this day in 1998 (the previous ones had been the so-called subcritical tests, which didn’t involve a true explosion). The testing begun on this day was codenamed Chagai-I and consisted of five explosions. The total yield of the explosions was between 6 and 13 kilotons.
The nuclear tests were performed in the Ras Koh hills in the Pakistani province of Balochistan. This is central-western Pakistan, a relatively dry and sparsely populated area. The head of the Pakistani government that ordered the tests to be carried out was Nawaz Sharif.
