#CTBTO successfully installed a Capacity Building System (CBS) at the National Data Centre (NDC) of Côte d’Ivoire, Station Géophysique de Lamto, N’Douci. This milestone strengthens the NDC’s ability to process and analyse International Monitoring System (IMS) data and International Data Centre (IDC) products, deepening our commitment to building technical capacity in States Signatories and supporting their contribution to our 🌏 verification efforts.

Delighted to meet with Foreign Minister Rashid Meredov in Ashgabat. Wonderful CTBT@30 event with all Central Asian States, hosted by the Ministry of Foreign Affairs of Turkmenistan. Appreciate the region’s support for the Treaty and its Intl. Monitoring System (IMS). Central Asia’s seven IMS stations contribute to the goal of a world free of nuclear test explosions.

A pleasure to begin my visit to Turkmenistan with a meeting with President Serdar Berdimuhamedov. 🇹🇲 has been with the CTBT from the very beginning, signing the Treaty on the day it opened for signature, and is home to primary seismic station PS44 in Alibek, a valued contribution to the Treaty’s verification system and to global peace and security. Grateful for the continued partnership in support of the CTBT.

Support for the #CTBT is nearly universal. With 187 signatures & 178 ratifications, the 🌍 determination to end nuclear test explosions is more powerful than ever. As the Treaty marks its 30th anniv. year, we stand together to reaffirm that commitment.
One Treaty. One Goal. Zero Tests.

In late April, 25 radionuclide and waveform operators from 22 countries came together in Vienna & #CTBTO TeST Centre in Seibersdorf for three days of training on the systems that keep station data authenticated and trusted across our global monitoring network 📡.
The majority were from G77 & Latin American and Caribbean States 🌍, reflecting how far the IMS reaches and the shared commitment to banning nuclear test explosions.

📉 50 experts. 28 countries. 3 days.
The HPC Workshop for Nuclear Test Explosion Monitoring wrapped up in Vienna earlier this month. In a hybrid format, participants worked with AI, deep learning & quantum algorithms - and came away with new ideas, new connections, and a shared commitment to a world 🌎 free of nuclear test explosions.
