Abstract
We present a research project intended to investigate the structure of Cumbre Vieja volcano in La Palma, Canary Islands, after the September-December 2021 Tajogaite eruption. Starting in the summer of 2023, we will deploy a dense network of 35 broadband seismometers provided by GFZ and University of Granada, that will add up to the ~20 permanent stations already in operation by the Spanish National Geographic Institute (IGN) and the Volcanological Institute of Canary Islands (INVOLCAN). In this way, we expect to obtain a dense coverage of the whole island with inter-station distances of about 5 km. This broadband network will be in operation for a period of about a year. Additionally, we will perform a series of large-N experiments using 200 geophones (provided by GFZ). First we will deploy these instruments along linear profiles across the island, in N-S and E-W directions. In a second stage, we will move the geophones to a bidimensional grid configuration centered at the eruption site. We estimate that inter-station distances will be of ~0.5 km in both cases, and the recording periods will span around 4-5 months per configuration. The data obtained from these deployments will be used to perform a dense receiver function analysis and ambient noise tomography to improve the knowledge of the shallow velocity structure of the volcanic rift around the eruption area down to a depth of a few km and to image the magma sources in the crust and uppermost mantle.
