Hot stuff – 15 years of satellite data over Mt. Etna



 
This animation displays the retrieved vertical displacements of Mt. Etna within the investigated 1992-2006 time interval. Data is based on ESA's ERS-1, ERS-2 and Envisat satellites.

Cumulative deformation maps
 
Cumulative (a) vertical and (b) east–west deformation maps retrieved by applying the SBAS-InSAR technique to an ERS-Envisat Synthetic Aperture Radar (SAR) dataset relevant to the 1992-2006 time interval, with superimposed main fault systems (black lines) and the anticline structure (A) at the base of Mt. Etna; the results are spatially referenced to the highlighted pixel located in the town of Catania (black box in the lower right corner of Figure (a)).

Mt. Etna, Sicily
 
This Envisat MERIS image acquired on 25 November 2006 captures smoke spewing from Europe’s largest active volcano, Mt. Etna. The 3350 m-high volcano resumed eruptions in early September this year and entered its highly active phase on 5 November, according to the National Institute of Geophysics and Volcanic Studies.
