“…There are two events when these differences are highest: 1817/1816 (related to Tambora eruption) shows up as the year with the highest difference in the whole series, but it is very closely followed by 1824/1823, which could have been affected by the eruption of the Galunggung (Indonesia) on 8 October 1822 (with a VEI -Volcanic Explosivity Index -of 5) (Bronto, 1989) and/or the eruption of the Usu (Hokkaido, Japan; VEI 4), which occurred sometime between march and October of that same year (Jousset et al, 2003).…”

“…Similarly, during an eruption, the ground may deflate as magma is discharged. Ground deformation model typically posit a source with simple geometry and try to fit it to the observed deformation (Mogi 1958;Jousset et al 2003;Fialko et al 2003), and finite element modelling methods have enabled increasingly detailed modelling of crustal dynamics (e.g. Foroozan et al 2010;Fialko et al 2003).…”

International audienceThis paper discusses results from a survey of volcanologists carried out on the Volcano Listserv during late 2008 and early 2009. In particular, it examines the status of volcano monitoring technologies and their relative perceived value at persistently and potentially active volcanoes. It also examines the role of different types of knowledge in hazard assessment on active volcanoes, as reported by scientists engaged in this area, and interviewees with experience from the current eruption on Montserrat. Conclusions are drawn about the current state of monitoring and the likely future research directions, and also about the roles of expertise and experience in risk assessment on active volcanoes; while local knowledge is important, it must be balanced with fresh ideas and expertise in a combination of disciplines to produce an advisory context that is conducive to high-level scientific discussion

“…Although such models account for only an elastic behavior, neglecting heterogeneities and structural discontinuities, they are widely used in the modeling of volcanic areas (Dvorak and Dzurisin 1997;Miura et al 2000;Lowry et al 2001;Jousset et al 2003;Lagios et al 2005;Sepe et al 2007) where cracks or discontinuities slightly alter the elastic constants but not the fundamental elastic behavior of a volcano (Dvorak and Dzurisin 1997). To reproduce the realistic hydrothermal/geothermal system (Fig.…”

Panarea volcano (Aeolian Islands, Italy) was \ud considered extinct until November 3, 2002, when a \ud submarine gas eruption began in the area of the islets of \ud Lisca Bianca, Bottaro, Lisca Nera, Dattilo, and Panarelli, \ud about 2.5 km east of Panarea Island. The gas eruption \ud decreased to a state of low degassing by July 2003. Before \ud 2002, the activity of Panarea volcano was characterized by \ud mild degassing of hydrothermal fluid. The compositions of \ud the 2002 gases and their isotopic signatures suggested that \ud the emissions originated from a hydrothermal/geothermal \ud reservoir fed by magmatic fluids. We investigate crustal \ud deformation of Panarea volcano using the global position- \ud ing system (GPS) velocity field obtained by the combina- \ud tion of continuous and episodic site observations of the \ud Panarea GPS network in the time span 1995–2007. We \ud present a combined model of Okada sources, which \ud explai ns the GPS results acquired in the area from \ud December 2002. The kinematics of Panarea volcano show \ud two distinct active crustal domains characterized by \ud different styles of horizontal deformation, supported also \ud by volcanological and structural evidence. Subsidence on \ud order of several millimeters/year is affecting the entire \ud Panarea volcano, and a shortening of 10−6 year−1 has been estimated in the Islets area. Our model reveals that the \ud degassing intensity and distribution are strongly influenced by \ud geophysical-geochemical changes within the hydrothermal/ \ud geothermal system. These variations may be triggered by \ud changes in the regional stress field as suggested by the \ud geophysical and volcanological events which occurred in \ud 2002 in the Southern Tyrrhenian area
