 Zusammenfassung: The Comprehensive Nuclear-Test-Ban Treaty (CTBT) prohibits all nuclear explosions. For detection of potential non-compliance, the International Monitoring System (IMS) with 321 stations is being installed. The International Data Centre in Vienna provides standard data products. The discrimination of the event character is the responsibility of the State Signatories who are encouraged to make use of additional data, so called national technical means. The explosive eruption of the Hunga Volcano on 15 January 2022 provides an ideal test case for reviewing established methods to analyse source processes. This is due to its enormous force and its explosive source mechanism close to an expected one but still featuring significant differences. Discriminating different kinds of explosive sources such as a nuclear test and a volcano eruption is a key task in the CTBT context. We apply standard techniques to all four data types, i. e. three waveform technologies (seismology, infrasound, and hydroacoustic) and atmospheric transport modelling of radionuclides. Assessing the potential of these methods to discriminate a source, we can show that they work very well to identify, investigate, and discriminate an event of interest. During discrimination we could not only exclude a shear-source (i.e. an earthquake) but also distinguish the volcanic explosion in contrast to a man-made explosion. However, some tasks remain difficult (e.g. strength and therefore yield estimation). In addition to evaluating the methods, we could relate our results with specific phases of the volcanic processes providing a more detailed insight of what happened during the eruption.
