R Salvage: Forecasting volcanic unrest using seismicity: The good, the bad and the time consuming: VUELCO conference, Barcelona 2013

21 Mar 2013 | Presentations | Contributor(s): Rebecca Olivia Salvage, Jurgen Neuberg

Work presented at VUELCO conference in Barcelona, Spain, 7th and 8th March 2013

J W Neuberg, M Thomas, K Pascal, S Karl, A Collinson; EGU2012:On the mutual relationship between conceptual models and data sets in geophysical monitoring of volcanic systems.

21 Mar 2013 | Presentations | Contributor(s): Jurgen Neuberg, Mark Thomas, Karen Pascal, Sandra Karl, Amy Collinson

Geophysical datasets are essential to guide particularly short-term forecasting of volcanic activity.. Key parameters are derived from these datasets and interpreted in different ways, however, the biggest impact on the interpretation is not determined by the range of parameters but controlled...

Jurgen Neuberg, Karen Pascal; EGU 2012: Quantifying the errors due to the superposition of analytical deformation sources

21 Mar 2013 | Presentations | Contributor(s): Jurgen Neuberg, Karen Pascal

The displacement field due to magma movement in the subsurface is often modelled using a Mogi point source or a dislocation Okada source embedded in a homogeneous elastic half-space. When the magmatic system cannot be modelled by a single source it is often represented by several sources, their...

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...

Global volcanic unrest in the 21st Century: An analysis of the first decadeVolcanic unrest is perhaps best defined as the deviation from the background or baseline behaviour of a volcano towards a level of activity, which is cause for concern in the short-term because it might be a prelude to an...

Volcanic unrest is the deviation from the background or baseline behaviour of a volcano towards a level of activity, which is cause for concern in the short term because it might be a prelude to an eruption. When volcanic unrest is preceded by lengthy periods of quiescence it is particularly...

Predicting changes in volcanic activity through modelling magma ascent rate (VUELCO Barcelona meeting, March 2013)

20 Mar 2013 | Presentations | Contributor(s): Mark Thomas, Jurgen Neuberg

It is a simple fact that changes in volcanic activity happen and in retrospect they are easy to spot, the dissimilar eruption dynamics between an effusive and explosive event, or simply the appearance of magma at the surface where it was not previously are signs hard not to miss. However to be...

J. Gottsmann EGU 2012 Abstract Vol. 14, EGU2012-2353, 2012

20 Mar 2013 | Publications | Contributor(s): Jo Gottsmann

In this presentation I explore magma chamber stress conditions prior to a large-magnitude andesitic eruption and associated pre-eruptive ground deformation and gravity field perturbations. The analyis is informed by constraints from multi-disciplinary investigations of the data-rich and ongoing...
