Journal ArticleDOI
Towards forecasting volcanic eruptions using seismic noise
Florent Brenguier,Nikolai M. Shapiro,Michel Campillo,Valérie Ferrazzini,Zacharie Duputel,Olivier Coutant,Alexandre Nercessian +6 more
TL;DR: In this paper, the authors used the properties of ambient seismic noise recorded over an 18-month interval to show that changes in the interior of the Piton de la Fournaise volcano can be monitored continuously by measuring very small relative seismicvelocity perturbations, of the order of 0.05%.
Journal ArticleDOI
Toward Forecasting Volcanic Eruptions using Seismic Noise
Florent Brenguier,Nikolai M. Shapiro,Michel Campillo,Valérie Ferrazzini,Zacharie Duputel,Olivier Coutant,Alexandre Nercessian +6 more
TL;DR: In this paper, the reproducibility properties of the ambient seismic noise recorded on the Piton de la Fournaise volcano were used to measure relative seismic velocity variations of less than 0.1 % with a temporal resolution of one day.
Journal ArticleDOI
3-D surface wave tomography of the Piton de la Fournaise volcano using seismic noise correlations
Florent Brenguier,Florent Brenguier,Nikolai M. Shapiro,Michel Campillo,Alexandre Nercessian,Valérie Ferrazzini +5 more
TL;DR: Brenguier et al. as discussed by the authors invert Rayleigh wave reconstructed from cross-correlations of 18 months of ambient seismic noise recorded by permanent seismological stations run by the Piton de la Fournaise Volcanological Observatory.
Journal ArticleDOI
Slow waves trapped in a fluid‐filled infinite crack: Implication for volcanic tremor
Valérie Ferrazzini,Keiiti Aki +1 more
TL;DR: In this article, the authors studied analytically normal modes trapped in a liquid-filled layer sandwiched between two solid half-space, and found that a slow wave, similar to the tube wave found by Blot, exists for all wavelengths.
Journal ArticleDOI
The April 2007 eruption and the Dolomieu crater collapse, two major events at Piton de la Fournaise (La Réunion Island, Indian Ocean)
Thomas Staudacher,Valérie Ferrazzini,Aline Peltier,Philippe Kowalski,Patrice Boissier,Philippe Catherine,Frédéric Lauret,Frédérick Massin +7 more
TL;DR: In this article, the authors present a chronology of two related major events in the recent activity of Piton de la Fournaise seen by the scientific networks of the volcanological observatory (OVPF/IPGP) and field observations, which allowed to back up the scenario of the caldera formation and quantify these two exceptional episodes.
