| Zusammenfassung |
| From May to September 2013 21 seismic stations were deployed around Snaefellsjökull
volcano, Iceland. We cross-correlate the 5 months of seismic noise and measure the Rayleigh
wave group velocity dispersion curves. We use a 3D tomography procedure to compute
velocity maps between 0.9 and 4.8 s. The results allow us to constrain the size
and depth of the magmatic reservoir as well as the geological structures beneath
Snaefellsjökull volcano. We provide accurate velocity models for the peninsula. |
