Since 10 years I enjoyed this place formerly known by bird‘s sounds. #MeinXJubiläum #MyXAnniversary . Now, I am more active elsewhere and hope you follow me where the birds are in the blue sky.

30 years of the #CTBT is a moment to be incredibly proud – of what we have achieved, the progress we have made and everyone who has contributed to this shared mission. But our work does not end here. Young people will take this mission forward with new energy and ideas. That is why we are launching the CTBT Young Leaders (CYL) — the #NextGen of advocates who will champion the Treaty and help shape its future.

Thirty years after the #CTBT opened for signature, the commitment to ending nuclear test explosions remains as important as ever. Thank you to Australia, Austria, Kazakhstan, the City of Vienna and all our partners and supporters as we work towards a world free of nuclear test explosions.
One Treaty. One Goal. Zero Tests. 30 years ago, States came together with a shared ambition: to end nuclear test explosions.
This Tuesday in Vienna, #CTBTO Executive Secretary @DrRobFloyd marked the 30th anniversary of the #CTBT alongside @MFA_Austria Minister @BMeinl, Filip Worotynski representing Mayor @BgmLudwig of @stadt_wien and @iaeaorg’s Director General @rafaelmgrossi at the Rathaus, at an event generously supported by 🇦🇺, 🇦🇹 and 🇰🇿.
The message is clear: the Treaty remains a cornerstone of the global non-proliferation and disarmament architecture, and its mission is more urgent and relevant than ever.

“As we celebrate the 30th anniversary of the #CTBT, we underline the Treaty’s significant contribution to international peace and security.” The 12th Ministerial Meeting of Friends of the CTBT concluded in New York with the adoption of a joint statement, reaffirming their commitment to achieving the Treaty’s entry into force.

What a great delegation.
It was a pleasure to welcome Christopher Yeaw, U.S. Assistant Secretary of State for Arms Control, Non-Proliferation and Stability; Matthew Napoli, Deputy Administrator NNSA; Ambassador Preston Wells Griffith III; and their colleagues to the Vienna International Centre, where we provided an overview of the International Monitoring System (IMS) facilities and the International Data Centre (IDC). I greatly appreciate the U.S. Government’s generous support.

Happy 30th anniversary to the CTBT and all who are supporting it. May this Treaty enter into force soon and live long. The non-testing norm holds.
30 years ago today, the world took a historic step towards ending nuclear test explosions. Much has been achieved since then. Our responsibility now is to build on these gains and pass them on to future generations.
One Treaty. One Goal. Zero Tests.

Today marks 30 yrs since the #UNGA adopted the #CTBT. Over the past three decades, the Treaty has contributed to strengthening global efforts to prevent nuclear weapon test explosions. Its verification system provides a unique capability to detect such tests, making an important contribution to intl. peace & security.
The growing demand for tritium from fusion startups raises two critical questions:
(1) can legacy stocks and existing production capacities meet this demand?
(2) are existing export control and accountancy procedures sufficient?

Interesting blog post by Peace Science Collaboration quoting the paper by Kalinowski & Trillo (2025) about remote observations of historic nuclear tests some of which were conducted underground and engineered for containment.

Readiness isn't built overnight. It is refined and demonstrated over time.
▶️Hear from #CTBTO On-Site Inspection Director Oleg Rozhkov on how the Integrated Field Exercise 2026 (#IFE26) will help validate capabilities, strengthen international cooperation, and advance operational readiness of the Treaty's on-site inspection component.

A magnitude 7.3 earthquake was recorded offshore near Chiapas, Mexico, on 17 July 2026 at 14:48:39 UTC.
A tsunami warning was triggered following the earthquake. Seismic waves from this event were recorded by Raspberry Shake stations in Kenya, over 14,000 km from the epicenter.

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.
