About CTBTO
The Comprehensive Nuclear-Test-Ban Treaty (CTBT) bans nuclear explosions by everyone, everywhere: on the Earth’s surface, in the atmosphere, underwater and underground.Activities by CTBTO
Satellite monitoring for On Site Inspection (OSI)
GlobalThe use of air-and-spaceborne multispectral imagery (MSIR) for classification and change detection in the inspection area, with the ultimate goal of limiting the search area and detecting features of interest.
Activity Type Research/Reports/AssessmentsNetwork Processing of detected signals to determine the events that have triggered them
GlobalDetection of events by on-site inspections for every signal detected is time consuming and expensive, hence the need for network processing of signals detected at seismic, infrasound and hydro-acoustic stations to determine the events that have caused these signals to be observed.
Activity Type AI Tools/SolutionsNET-VISA (NETwork processing Vertically Integrated Seismic Analysis)
GlobalImprovement of the current rule-based system.
Activity Type AI Tools/SolutionsSeismic aftershock monitoring
GlobalMonitoring changes in the geological structures caused by a possible nuclear explosion and classifying “weak” detections produced to enable separation of noise from signals of interest (aftershocks).
