Due to their size, acoustic recordings can be made available upon request. The data of hydroacoustic events allocated in the seismic catalogue can be accessed in the Supplementary Material.Volcanic processes generate a variety of seismic events that can be detected by both on-land and underwater sensors. During the 2021 subaerial eruption of the Tajogaite volcano on La Palma Island (Canary Islands, NW Africa), an underwater acoustic sensor was strategically deployed to monitor seismic activity. This study presents marine passive acoustic monitoring data from a moored hydrophone deployed offshore at a depth of 77 m and 7 km from the volcanic vent, both during and after the eruption. We compare hydrophone recordings with island's seismic network and earthquake database from the Instituto Geográfico Nacional (IGN). By calculating acoustic metrics and analyzing low-frequency bands (< 100 Hz), we identified 712 impulsive acoustic signals consistent with seismic events recorded in the seismic catalogue. These acoustic signals were double-pulsed, low-frequency (≤ 50 Hz with peak frequencies ≤ 15 Hz) and exhibited sound levels that well correlated with earthquake magnitudes. Our findings demonstrate that shallow-water hydro-acoustics can detect and estimate the magnitude of volcano-tectonic earthquakes in the studied scenario. These results encourage for the integration of hydro-acoustic monitoring in conjunction with on-land seismic stations to enhance the overall monitoring of the investigated volcanic area seismic activity.Acoustic sampling for this work was supported by the Spanish Institute of Oceanography (IEO-CSIC) through the VULCANA-III-IV projects (IEO-CSIC-2021-2026) and with special funding from the Ministry of Science and Innovation of the Spanish Government (20223PAL005). We extend our sincere gratitude to the following organizations for their invaluable assistance during the volcanological crisis at La Palma Island: Capitanía Marítima of S/C Tenerife, Guardia Civil, SASEMAR, Protección Civil, the Marine Reserve of La Palma, Fuencaliente ZEC, Canary Islands Government, PEVOLCA, and Cabildo de La Palma. Furthermore, we would like to convey our deepest gratitude to the officers and crew of the R/V Ramón Margalef and Ángeles Alvariño from IEO-CSIC, as well as the technicians of ACSM (ROV-Liropus 2000) for their exceptional support during our time at sea. Their dedication and expertise greatly contributed to the success of our research efforts. The authors would like to thank the Agreement between PROMOTUR Turismo Canarias, S.A. and the Spanish National Research Council (CSIC), the University of La Laguna (ULL), the General Foundation of the University of La Laguna (FGULL) and the University of Las Palmas de Gran Canaria (ULPGC) for the joint implementation of actions for intelligent management and the creation of Blue Tourism product, within the framework of the Recovery, Transformation, and Resilience Plan (Next Generation EU Funds), and Order No. 257/2023 of the Minister of Tourism and Employment, granting a financial contribution to the public company PROMOTUR Turismo Canarias, S.A. for the execution of cohesion actions in destinations, integrated into the Canary Islands Territorial Plan. JAT was funded by the Catalina Ruiz postdoctoral program from the Consejería de Economía, Conocimiento y Empleo of the Canary Islands Government and the European Social Fund from the European Commission (Project APCR2022010008) for a two-years stay at the IEO-CSIC.
