The Works Department of the Ascension Island Government are pleased to announce the successful completion of the construction of, 8 Array Sites, 1 CPF (Central Process Facility) and 1 Relay Station.
Five of the Array sites are located on the road to Two Boats, 1 to the rear of the Golf Course, and 1 towards the ranges at North East Bay.
The Relay Station is situated at Green Mountain and the CPF at Travellers Hill.
 
How did this all come about?
On September 10, 1996, the United Nations General Assembly voted to approve a treaty prohibiting all nuclear tests. The Comprehensive Test Ban Treaty was signed by 130 nations.
The CTBTO, The Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization is based in Vienna, it is an international organization which carries out the necessary preparations for the effective implementation of the treaty.
The CTBTO funded the project which was called INFRASOUND and additional workforce was recruited from St Helena for the construction of the sites. The project commenced in April of this year and was completed in September, within budget and 3 months before schedule. CTBTO commended the workforces’ high standard of quality workmanship and production.

Austrian, Alfred Kramer and Russian Pavel Martysevich, are both Infrasound Officers working with the CTBTO, they visited Ascension last month to install vital monitoring equipment at the Central Process Facility, Travellers Hill.
When asked “how do the sites work?” Alfred and Pavel explained;
“When a nuclear explosion occurs it immediately generates waves which travel through the earth, each array site contains numerous underground sensor devices which can detect all sounds. All information collected in sent to the Central Process Facility at Travellers, it is then sent onto Headquarters in Vienna”
In addition to nuclear explosions the Array Sites can also detect, volcanoes, concord taking off, satellite crashes, storms and earthquakes.
CTBTO are constructing INFRASOUND sites worldwide, one has already been constructed on Tristan, and Ascension is the 30th site to be completed.
