Close to Mayotte Island, a small volcano named Fani Maore was discovered in 2019. The sudden seismicity it triggered led to the creation of the REVOSIMA group and cruises, aiming at monitoring the activity of the volcano. Among the deployed sensors, MAHY, a network of four Autonomous Hydrophones (AuH), was deployed in 2020. Hydrophones enable to monitor many sources. Two signals of interest are the pupose of this dataset: P-phases, which are compressional seismic waves generated by earthquakes, and H-waves, which are in this case hydroacoustic signals generated by lava-seawater interaction. Using the hydroacoustic picking model TiSSNet and the associator TAPAAs, a catalog was automaticaly created for each of these signal types.
