Iceland: New Method to Image Reykjanes Peninsula High-Enthalpy Geothermal Fields

3D S-wave velocity imaging of Reykjanes Peninsula high-enthalpy geothermal fields with ambient-noise tomography (Journal of Volcanology and Geothermal Research)


Tomographic imaging based on ambient seismic noise measurements has shown to be a powerful tool, especially in areas like Iceland, where the microseism illumination is excellent.

In this paper, we produce a 3D S-wave tomographic image over the western Reykjanes Peninsula high-enthalpy geothermal fields and evaluate the reliability of the tomographic results for different resolutions through simulated and real data.

This study shows the potential of ambient noise tomography as complementary seismological tool for reservoir characterization.
