Is Volcan Agua extinct?

I’ve had the pleasure of visiting Guatemala three times, the first time was in 2005, the second time was in 2006, and the third time was in 2015, and it was the one thing I’m passionate about which drew me to Guatemala, volcanoes. Now Guatemala has a bunch of fascinating volcanoes but what we know…

The Woolly Mammoth Guide to Icelandic Volcanism 2018 – Chapter 1

Reykjanes Ridge and Eldey-Geirfuglasker Volcanic Belt A year and a half ago I wrote what I thought would be the end of writing about Icelandic volcanoes for quite some time. Reality obviously caught up with me, and I had to write quite a few more articles. The Woolly Mammoth was not intended to be left…

Volcano at fault: Neenach and the art of moving mountains

The San Andreas fault makes a great bend around the city. It leaves its citizens well separated from the real America. On the rim of the Pacific, Los Angeles has become the ultimate laid-back city. The beach-and-body life, the Pasadena coffee culture, the dancing on the highways (ok, that was only in that movie, I…

The Usual Suspects

This week there are three volcanoes worthy of attention. So, I thought I would write a brief update on them since we have covered them either recently, or in detail. Without further ramblings let us go on to Gunung Agung. And as I came to my final and third volcano life coughed up a fourth…

Gunung Agung and the potential future

Most people have by now noticed that Gunung Agung has stopped erupting. And to understand why that has happened, and what will happen soon, we need to look at what happened during the eruption. We also need to look at what is currently happening. When a volcano is showing no visible signs of activity, we…

The eruptive past of Indonesia

Gunug Agung has had impressive eruptions in the past week. So far, in spite of the publicity, the event has remained relatively minor. We do not know whether these are the initial rumblings and in the next weeks and months there will be far larger explosions, or that this suffices to relieve the pressure inside…

Agung again: the eruption of 1963

There was a lot going in the 1960’s. This was the time of the generation battle, where the children who had grown up in a time of austerity and a cold war, rebelled and looked for something different – exploring, ignoring the boundaries but never quite finding what they were looking for. Martin Luther King…

History of Öræfajökull

Iceland has ice. Glaciers cover 10% of its landscape, including its highest volcanoes. Of its frequent eruptors, only Hekla is (almost) ice free. Katla, Bardarbunga, and Grimsvötn, which together account for the large majority of eruptions, are all hidden underneath ice sheets, which gives problems studying the volcanoes themselves. But a more serious issue is…

Öraefajökull – A challenge for volcanology

A couple of years ago I was asked on a radio show which volcano in Iceland I wanted least to erupt. I quickly answered Öraefajökull. It confused everyone, and I got bogged down in explaining why an unknown (to the layman) volcano would be that bad. It is though true, if there is a single…

Making a Map

A quick overview of my current VCMap project, which can currently be found at http://www.volcanocafe.org/vcmap I would like to start off by thanking Spike Page for being the inspiration for this project.  A couple of weeks ago, Spike wrote on Spike’s Facebook page asking for someone to test out a Google Earth file. This file…
