STRUCTURAL CONTROLS ON MONOGENETIC VOLCANISM: THE GARROTXA VOLCANIC FIELD CASE STUDY
04 Sep 2013 | Contributor(s): Xavier Bolos, Stephanie Barde-Cabusson, Jo Gottsmann, Joan Marti, Dario Pedrazzi, Llorenç Planaguma, Antonio Camacho, Adelina Geyer Traver, Erika Ronchin
The factors controlling the precursory activity in monogenetic volcanic fields are still poorly understood, which makes that eruption forecasts in these systems is not very accurate. The fact that in monogenetic volcanism each eruption has a different vent suggests that volcanic susceptibility...

Deep Magmatic Unrest: ground uplift and magma rise at Uturuncu volcano
07 Aug 2013 | Contributor(s): James Hickey, Jo Gottsmann, Rodrigo del Potro
Uturuncu volcano in southern Bolivia has been steadily inflating since at least 1965, and combined with shallow seismicity and near-summit active fumaroles represents a volcanic system showing significant signs of unrest. This study focuses on the mechanism driving the 70 km wide region of ground...

VOLCANIC UNREST IN THE 21ST CENTURY
09 Apr 2013 | Contributor(s): Jo Gottsmann, Georgia Phillipson
One of the most pertinent issues in volcanic risk management is the question whether volcanic unrest will culminate in an eruption in the short-term or not. This question is particularly difficult to answer at volcanoes where unrest is preceded by lengthy periods of quiescence and where hard data...

Exploring the pre-eruptive geodetic signature of a future M7 explosive eruptionRecent eruptions of intermediate magmas in volcanic arcs with well-documented pre-eruptive geodetic signatures were of small to modest magnitude. The pre-eruptive ground deformation of a future large magnitude...

A glimpse into the future - Earth Science on Trial! (VUELCO & CoV7, Colima 2012)
20 Mar 2013 | Contributor(s): Richard Bretton, Jo Gottsmann
The United Nations has played a vital role in improving the governance of natural hazards including volcanoes. The UN's International Decade of Natural Disaster Reduction 1990-2000 generated an increased interest in and concern for disaster-related issues and in particular proactive risk...

Reflections on the L'Aquila verdict - A candid risk assessment of the role of the earth scientist and some suggestions for risk management (VUELCO Barcelona 2013)
20 Mar 2013 | Contributor(s): Richard Bretton, Jo Gottsmann, Robert Stephen Sparks
The scientific community's public reaction to the conviction and sentencing of seven Italian scientists was immediate, passionate and, too large extent, ill-informed. The after-shock waves were predictable; the Twitter feeds, blogs and press releases vitriolic. There was unanimity that we were...

Hazard Assessment Reports must be in writing but what should they contain and why? (VUELCO Barcelona 2013)
20 Mar 2013 | Presentations | Contributor(s): Richard Bretton, Jo Gottsmann
Immediately after the VUELCO-Colima 2012 volcanic unrest simulation exercise, feedback was obtained from the two Civil Protection authorities that took part – the authorities for the States of Colima and Jalisco respectively. The feedback was mixed and yet very informative. It covered the content...

ADVANCES IN INTEGRATED VOLCANIC GEODETIC MODELLING AND APPLICATION TO DEEP-SEATED UNREST AT UTURUNCU VOLCANO, BOLIVIA
18 Mar 2013 | Presentations | Contributor(s): James Hickey, Jo Gottsmann
Moving on from simple, analytical deformation models, we have developed a suite of numerical models that can account for a range of realistic crustal complexities and are thus more consistent with multi-disciplinary constraints. Using Finite Element techniques through commercial code COMSOL...
