The pre-eruptive episode was characterized by seismicity and ground deformation that started only 9.5 days before the eruption. In this study, we applied seismic interferometry to the data recorded by six broadband seismic stations, allowing us to estimate velocity variations during the weeks preceding the eruption. About 9.5 days before the eruption, we observed a reduction in the seismic velocities is registered next to the eruptive centers that opened later. Furthermore, this zone overlaps with the epicenters of a cluster of volcano-tectonic earthquakes located at shallow depth (< 4 km) and detached from the main cluster of deeper seismicity. We interpret the decrease in seismic velocities and the occurrence of such a shallow earthquake cluster as the effect of hydrothermal fluid released by the ascending magma batch and reaching the surface faster than the magma itself.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380584340720690316","@type":"Researcher","foaf:name":[{"@value":"Iván Cabrera-Pérez"}]},{"@id":"https://cir.nii.ac.jp/crid/1380584340720690178","@type":"Researcher","foaf:name":[{"@value":"Luca D’Auria"}]},{"@id":"https://cir.nii.ac.jp/crid/1380584340720690191","@type":"Researcher","foaf:name":[{"@value":"Jean Soubestre"}]},{"@id":"https://cir.nii.ac.jp/crid/1380584340720690187","@type":"Researcher","foaf:name":[{"@value":"Monika Przeor"}]},{"@id":"https://cir.nii.ac.jp/crid/1380584340720690176","@type":"Researcher","foaf:name":[{"@value":"José Barrancos"}]},{"@id":"https://cir.nii.ac.jp/crid/1380584340720690320","@type":"Researcher","foaf:name":[{"@value":"Rubén García-Hernández"}]},{"@id":"https://cir.nii.ac.jp/crid/1380584340720690314","@type":"Researcher","foaf:name":[{"@value":"Jesús M.
