It seems that for unknown reasons the activity has changed at depth so that El Hierro has become far more active than previously.…
I have for quite some time had an issue with the Mogi-model as soon as it is used outside of a central volcano. At a central volcano it makes sense to use a point sourced half sphere as a model for predicting amount of magma intruding into the system from given GPS-coordinates. If only the…
