Static and dynamic seismic imaging of piton de la fournaise

Abstract

Data from the Piton de la Fournaise Volcanological Observatory (“Observatoire Volcanologique du Piton de la Fournaise”, OVPF) and from the Undervolc project (Brenguier et al. in Seismol Res Lett 83(1):97–102, 2012) have been used to image the interior of the volcano. Two different approaches have been carried out. One is noise-based and allows both imaging and monitoring. The other is based on P-wave first arrival times of local earthquakes to derive 3D tomographic models.
