Chagai-I, Nuclear test site in Chagai District, Pakistan
Chagai-I was a nuclear weapons test conducted in the Ras Koh Hills in Chagai District. Five underground devices were detonated simultaneously, creating a combined explosive force that registered on seismic instruments worldwide.
The test occurred on 28 May 1998 and made Pakistan the seventh nuclear-armed nation. This followed nuclear developments by a neighboring country and significantly altered the regional balance of power.
This location marks a turning point in Pakistan's defense strategy and reflects the role of technological advancement in national security. The decision to conduct the test was closely tied to regional tensions and the desire to shift the military balance.
The test site is located in a remote area of Balochistan Province and is not open to visitors. The region is sparsely populated and characterized by harsh terrain.
The explosions were so powerful that they were measured by seismometers across the world and immediately alerted the international community. This allowed the blast magnitude to be confirmed remotely without on-site verification.
