Analytical and 3-D numerical modelling of Mt. Etna (Italy) volcano inflation

ERS InSAR Observations of Mt. Etna volcano: Magma inflation and radial spreading

We present a synthesis of ERS-1 and ERS-2 differential SAR interferometry (InSAR) observations of Mt. Etna volcano over roughly the past ten years from 10022002. Through this time period Mount Etna underwent a cycle of eruptive activity starting with a large flank eruption that ended in March 1993, followed by two years quiescence, with resumed summit activity starting in the summer of 1995, cu...

Deep Earthquakes as a Precursor of the September- October 1989 Flank Eruption at Mt. Etna Volcano (italy)

The September-October 1989 flank eruption at Mt. Etna marked a change in the recent eruptive style of the volcano. Seismicity, at mid (order of months) and short (order of days) time, preceding the eruption onset has been analysed by means of D (time fractal dimension), and of materials science equation. The behaviour of the upper and lower crust volumes has been investigated, by considering sh...

Comparing satellite and ground-based observations of paroxysmal degassing events at Etna volcano, Italy

Denoising gravity and geomagnetic signals from Etna volcano ( Italy ) using multivariate methods

Multivariate methods were applied to denoise the gravity and geomagnetic signals continuously recorded by the permanent monitoring networks on the Etna volcano. Gravity and geomagnetic signals observed in volcanic areas are severely influenced by meteorological variables (i.e. pressure, temperature and humidity), whose disturbances can make the detection of volcanic source effects more difficul...

Identifying seismicity patterns leading flank eruptions at Mt. Etna Volcano during 1981-1996

Seismicity time properties of the Etna Volcano (Italy) are investigated through a systematic pattern recognition analysis. Mean Hypothesis Testing (MHT) has been applied to a long time database of instrumental data recorded from 1981 to 1996 to identify relevant correlation among seismic patterns, main seismogenic volumes and the eight flank eruptions occured in the same period. Time evolution ...
