Deep magmatic roots of Katla…

For every person that is interested in volcanoes and complex geology, Iceland is probably something special. A unique place where the MAR intersects a mantle plume, or vice-versa. A beautiful island filled with powerful volcanoes and other complex volcanic and hydrothermal features. All in one nice little spot. Of the entire Icelandic volcanic lot, the most…

Questions and Answers – A 1947 commemorative article series

I had planned the third part be an extension of how the sinusoidal 3D-wedge model influenced eruptions over time and how it explains distal eruptions along the fissure swarm. But, there has been a wealth of questions and comments that I felt needed to be answered that do not belong to the article series itself,…

Iceland’s secret heart: Hofsjökull volcano

Where the blood flows calm like a purling river Late March, a few minor earthquakes happened in the sleeping heart of Iceland. They were hardly worth noting, at M1, and 4-5 km deep. The centre of Iceland is far from anywhere. It is calm and is hard to reach, thus receives little attention and fewer…

Form follows function – A 1947 commemorative article series

In physics, there is a famous tenement that reads as, ‘cause and effect’. But, for Hekla I find that the founding principle of the Bauhaus school of modernist architecture is far better suited to express what I will be trying to model and express here. It states that the form of a building will at…

Remodelling Hekla – A 1947 commemorative article series

The point of this series of articles is to propose an alternative model of dynamics, driving forces and magma fractionation at Hekla. It is thus not utilizing the standard volcanological model of how a mantleplume stratovolcano function. 5 years ago, I started to have grave misgivings about how we interpret and model Hekla, as such…

The USGS Volcano Observatories: can we save VDAP?

This April-1 post is correct only in describing what the USGS and VDAP do – apart from that, the truth, the whole truth and nothing but the truth is fundamentally lacking in this spoof. There is also no Mount Rainier crisis, nor has Microsoft captured the CVO outreach! (But regrettably, the proposed 15% budget cut…
