The Comprehensive Test Ban Treaty (CTBT), which seeks to fully halt critical nuclear tests, opened for signature. India sees the CTBT as no different from the nuclear Non-Proliferation Treaty (NPT), which it vehemently opposes as discriminatory. Moreover, the work-in-progress treaty has achieved a key objective — preventing countries from conducting any further nuclear tests. The auxiliary seismic stations supplement the work of the primary stations. “Hydroacoustic monitoring makes use of the unique phenomenon of sound waves being trapped in that layer,” says CTBTO.
