HPC Workshop for Nuclear Explosion Monitoring
CHI Rodrigo
Dear Colleagues,
We are pleased to invite you to the 3rd edition of the HPC Workshop for Nuclear Explosion Monitoring, taking place from 11 to 13 May 2026 in a hybrid format—online and in-person at the Vienna International Centre, Vienna, Austria.
The International Data Centre (IDC) at the CTBTO continues to enhance its technical capabilities in operating the International Monitoring System (IMS). This workshop aims to identify innovative solutions to improve modelling and data analysis across all technologies.
Workshop Objective
The workshop will explore advancements and innovations in the application of High-Performance Computing (HPC) & Machine Learning (ML) in monitoring nuclear explosions across land, ocean, and atmosphere utilizing technologies from the seismic, hydroacoustic, infrasound and radionuclide domains with the support of atmospheric transport modelling.
Topics of Interest (including but not limited to)
We invite you to submit your abstracts covering the following topics:
- Full-wave SHI (seismic, infrasound, hydroacoustic) modelling in complex environments
- 3D long-range acoustic propagation modelling
- Generation and use of 3D tomographic velocity models
- Radionuclide detector-based simulations
- Numerical Weather Prediction (NWP) modelling for the atmosphere and ocean
- Simulation of explosions, cavity formation, subsurface gas transport, and prompt atmospheric releases
- Uncertainty quantification and adaptive learning
- Artificial Intelligence/Machine Learning (AI/ML) for:
- Digital twins (DTs)
- Atmospheric transport and radionuclide source localization
- Anomaly detections of atmospheric radioactivity
- Instrument failure detection and data quality assessment
- Signal and event detection, classification, discrimination, and data fusion
- Array processing
- AI tools for code translation to modern architectures and languages
- Implementation in operational settings
- Implementation to assist in IMS station maintenance
- Early applications of quantum computing in nuclear explosion monitoring
- SHI HPC methods and algorithms applied to civil and scientific applications
Workshop Format:
The workshop will feature keynote talks, oral sessions (both online and in-person), and an in-person poster session.
Abstract Submission
Please submit your abstract by 16 January 2026 via the submission portal. https://ctnw.ctbto.org/ctnw/event/11479
Financial Support
Limited financial assistance may be available. Requests must be made during registration and no later than 16 January 2026. Support will be considered only for participants whose abstracts are accepted. We encourage applicants to seek funding from non-CTBTO sources first.
