Sounds and shakes

In January, the world experienced the loudest bang of the century – and that of the previous century as well. The sound wave of Hunga Tonga was heard across the Pacific ocean in Alaska. The air pressure wave traveled around the world – and again. And again. The ocean wave caused a tsunami across the…

Lava rocks! (republication)

While we are waiting for more information (and daylight) on the large Pacific eruption, here is a repost. It complements the previous post on igneousity (for which surely the ig-nobel prize was invented?). Enjoy. What’s in a name. Would lava by any other name smell as sweet? Perhaps that is not the right question: lava…

Iceland: Plumbing the Plume

In the last decade, science has been under increasing attacks and have lost in status among the general population. Where famous scientists a century ago could rake in some serious dosh by going on lecture tours explaining their findings, today’s scientists are increasingly unknown and scorned by the general population. Instead, we see the rise…

The Current Volcanic State of Affairs

I am taking this opportunity to look at 5 volcanoes that at least I find interesting. I am doing this out of the perspective of the life-curve of an eruption. I find this perspective to be interesting, and I think that it is something that would be both entertaining and informative for our dear readers.…

Geothermal Risk Part 1: Muddy Business

I am writing this the day before the already failed COP26 meeting in Glasgow. Failed in the respect that neither the leaders of China, nor Russia, will partake. Failed also in the respect that the leaders of Japan, Australia and Brazil are travelling there hellbent on stopping or slowing down any progress. Failed in the…

The curious case about seemingly endless energy

How’s that for a humdinger of a clickbait headline? As clickbaity as it might seem, it is still true, but I freely admit that it comes with a couple of hippopotamus sized caveats. Firstly, I should probably state that this article is about geology, geophysics and tectonic plates, and not as such about volcanoes, I…

Volcano on the rocks

People need mementoes. They are small things (normally) with little intrinsic value (often), but which carries a memory which is far more valuable to the owner than the item is in itself. It can be a bit of jewelry, a cup, or a chair, or even a pebble. Or it can be one of many…

Apocalypse

A guest post by Tallis The very worst case scenarios are rarely considered for disasters and for usually a good reason. They are either so unlikely or so boring that there is no point in worrying or thinking about it. The worst case impact event is one that would completely destroy the Earth and make…

The Missing Piece Part 3: Endgame 

Some things are so easy to miss and once they are noticed, we either crawl into a fetal position and cry ourselves to sleep or become very excited over the new prospect. I have done both recently and formulated my own hypothesis, concerning silicic systems and their dynamics. After looking at the previously mentioned supercomplexes,…
