dc.description | Data availability The seismic catalogue of IGN is publicly available at: https:// www. ign. es/ web/ ign/ portal/ sis- catal ogo- terre motos. The seismic catalogue of INVOLCAN is available under request to Dr. Luca D’Auria (ldauria@iter.es). The LOTOS code is publicly available at: www. ivan- art. com/ scien ce/ LOTOS. An online version of the code with the La Palma dataset is available in: Koulakov Ivan. (2022). Data and program codes to reproduce the results of seismic tomography for La Palma Island [Data set]. Zenodo. https:// doi. org/ 10. 5281/ zenodo. 65893 67. The digital elevation model used in all figures and historical lava flows of Figs. 1 and 3 were downloaded from the public graphic repository of GrafCan (www. grafc an. es). The 2021 lava flow was downloaded from the European agency Copernicus Emergency Management Service (httts://emergency.copernicus.eu/mapping/list-of-components/ EMSR546). The software used to generate Fig. 1, Figs. S1, S2 and S3 was QGIS 3.22 (https:// www. qgis. org). The software used to generate Figs. 3, 4 and 6, Figs. S4, S5 and S6 is the LOTOS code. | es_ES |

dc.description.abstract | For the first time, we obtained high-resolution images of Earth's interior of the La Palma volcanic eruption that occurred in 2021 derived during the eruptive process. We present evidence of a rapid magmatic rise from the base of the oceanic crust under the island to produce an eruption that was active for 85 days. This eruption is interpreted as a very accelerated and energetic process. We used data from 11,349 earthquakes to perform travel-time seismic tomography. We present high-precision earthquake relocations and 3D distributions of P and S-wave velocities highlighting the geometry of magma sources. We identified three distinct structures: (1) a shallow localised region (< 3 km) of hydrothermal alteration; (2) spatially extensive, consolidated, oceanic crust extending to 10 km depth and; (3) a large sub-crustal magma-filled rock volume intrusion extending from 7 to 25 km depth. Our results suggest that this large magma reservoir feeds the La Palma eruption continuously. Prior to eruption onset, magma ascended from 10 km depth to the surface in less than 7 days. In the upper 3 km, melt migration is along the western contact between consolidated oceanic crust and altered hydrothermal material. | es_ES |
