Modelling Magma Propagation in Three Dimensions – Or: How I Learnt to Stop Worrying and Love Simplicity

Modelling Magma Propagation in Three Dimensions – Or: How I Learnt to Stop Worrying and Love Simplicity
Nature is complex, models not as much. A real eruptive fissure at Fagradalsfjall, Iceland, in 2022 (photo by Drumstick21, Wikipedia) is "fed" by a simulated dyke (modelled with SAM, Mantiloni et al., 2023) advancing in a stress field.

The crisis unfolding these days in Grindavík, Iceland reminds us of how important it is to forecast volcanic activity. Predicting the outcomes of volcanic unrest, or a magmatic intrusion making its way towards the surface, essentially amounts to three questions. Will there be an eruption? How much time before it starts? Where exactly will the eruption occur? Answering any of these questions is a d ...[Read More]

How has the Gibraltar slab influenced the Alboran domain deformation?

Figure 1. Topography of the Gibraltar Arc region. The shaded area indicates the position of positive seismic velocity anomaly supposedly representing the position of the slab at 270 km depth from seismic tomography (Amaru, 2007). The purple line shows the position of the modelled cross-section for the model shown in this blog. Blue dots indicate the regional intermediate seismicity (between 40 km ...[Read More]
