Title: | Capturing the fingerprint of Etna volcano activity in gravity and satellite radar data | Journal: | Scientific Report | Series/Report no.: | /3 (2013) | Issue Date: | 30-Oct-2013 | DOI: | 10.1038/srep03089 | Keywords: | Microgravity Ground deformation SAR Interferometry Volcano monitoring Etna volcano |
Subject Classification: | 04. Solid Earth::04.08. Volcanology::04.08.06. Volcano monitoring | Abstract: | Long-term and high temporal resolution gravity and deformation data move us toward a better understanding of the behavior of Mt Etna during the June 1995 – December 2011 period in which the volcano exhibited magma charging phases, flank eruptions and summit crater activity. Monthly repeated gravity measurements were coupled with deformation time series using the Differential Synthetic Aperture Radar Interferometry (DInSAR) technique on two sequences of interferograms from ERS/ENVISAT and COSMO-SkyMed satellites. Combining spatiotemporal gravity and DInSAR observations provides the signature of three underlying processes at Etna: (i) magma accumulation in intermediate storage zones, (ii) magmatic intrusions at shallow depth in the South Rift area, and (iii) the seaward sliding of the volcano’s eastern flank. Here we demonstrate the strength of the complementary gravity and DInSAR analysis in discerning among different processes and, thus, in detecting deep magma uprising in months to years before the onset of a new Etna eruption. |
