Seismic Tomography of a Newborn Volcano
Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.Abstract On 19 September 2021, in La Palma, Canary Islands (Spain), a new volcano, later named Tajogaite, erupted. We determined the shallow seismic tomography model of Tajogaite Volcano, including the 3D distributions of Vp, Vs, and Vp/Vs. The tomography of the volcanic edifice has been performed using a combination of a three‐component amplitude ...
