Towards a probabilistic scheme: How can we recognize and track non-magmatic unrest and related hazards?
18 Feb 2014 | Contributor(s): dmitri rouwet, Laura Sandri, Warner Marzocchi, Jo Gottsmann
Eruption forecasting is a major goal in volcanology. The intrinsic complexity and non-linearity of volcanic systems has recently led to an intertwining of deterministic to probabilistic eruption forecasting methods. However, many volcanoes often pass states of non-eruptive and non-magmatic unrest...

Global volcanic unrest in the 21st century: An analysis of the first decade
16 Sep 2013 | Contributor(s): Jo Gottsmann, Rosa Sobradelo
We define volcanic unrest as the deviation from the background or baseline behaviour of a volcano towards a behaviour which is a cause for concern in the short-term because it might prelude an eruption. When unrest is preceded by periods of quiescence over centuries or millennia it is...

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...

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...
