As we celebrate the 20th anniversary of the United Nations’ official recognition of Turkmenistan as a neutral State, I am inspired by the principles that underpin Turkmenistan’s much-applauded policy: cooperation, peace, security, development. For the last two decades, similar values have guided the development of the CTBT into one of the principal pillars of the non-proliferation and disarmament regime.

PS44 is a highly sensitive station consisting of seismic arrays (as opposed to three-component stations) – groups of individual sensors deployed in a specific geometric pattern.
PS44 is a Primary seismic station of the International Monitoring System and one of more than twenty arrays that contribute data to the verification regime of the CTBTO. It is an important station for identifying seismic events in the region it is situated, and also on a world-wide scale.

PS44 consists of 10 sets of seismic sensors. IMS seismic array stations can consist of up to 25 such sets.
