Abstract

We will present new volcano deformation observations for volcanoes in Italy (Mt. Etna) and Kamchatka (various) using interferometric synthetic aperture radar (InSAR) form the Envisat ASAR. These observations span the 2003-2005 time frame. Preliminary observations into 2005 for Mt. Etna show some interesting deformation signals that we hope to quantify further in terms of magmatic and/or structural deformation processes. For Kamchatka (and some Kuril Island volcanoes) 2005 data is yet to arrive with a few exceptions. So far the story in this highly active island arc is one of essentially no deformation, with the exception of Uzon caldera, which was actively deforming until 2003 (Radarsat-1 observations) but was not deforming from 2003-2004.
