As time goes by we understand more and more about the activity under El Hierro. The Canarian Hotspot has several plumeheads reaching up under the volcanically active islands in the Island chain. It seems that for unknown reasons the activity has changed at depth so that El Hierro has become far more active than previously.…
UPDATE And in record time the eruption at Palena was debunked. I am though leaving the text as it is. The real-time minutiae of the debunking is to be found in the comments. /CARL The end of the year gave a lot of volcanic news, and the beginning is no less hectic. News is starting…
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…
Dr Boris Behnke gave us the honor of a visit and explained how Etna functions as a reply to Alyson and dfm. Quote:” We know pretty well how magma moves below and into Etna. Usually when we get seismic signals at 15-25 km depth and a strong increase in soil CO2 emission at the base…
During the last few days activity has continued at El Hierro even though earthquake activity has decreased a lot. Harmonic tremor is though still increasing and GPS uplift is rather dramatic with maximum values at 75mm. With a bit of internet-spelunking I have tracked down where the maximum activity is, an indicator of where a…
