Continental rifts are a prime example of how the forces at work beneath our feet are constantly shaping our world, and often host volcanic activity. The patterns and distribution of volcanism in rift settings, however, is far from intuitive. The picture gets even more complicated if we look between the segments that often make up …[Read More]

Exploring the Evolution of Rift Magmatism through Numerical Modelling
Continental rifts are a striking manifestation of the forces at work in the Earth’s interior and are often associated with volcanic activity. Contrary to intuition, volcanism is not confined to rift grabens, but migrates as the rifts evolve. How and why this happens is still not clear. This week, Gaetano Ferrante from Rice University, Houston …[Read More]
Modelling Magma Propagation in Three Dimensions – Or: How I Learnt to Stop Worrying and Love Simplicity
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 …[Read More]
