Snow is beautiful. It turns the world white and unblemished. Children love it for play, grown-ups love it for what it hides. Soon the snow will melt again, or worse, it will age like the world ages, lose its colour and become pockmarked with dirt. The beauty is temporary, here today, gone tomorrow. What was…
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…
The Indian ocean can be a paradise. It has tropical beaches, smiling people, and blue ocean. But a paradise does not come out of nowhere; these tropical island paradises form in violence. Peace only comes after turmoil, when the forces of destruction finally give up, having created where they sought to destroy. Every tropical island…
The hill rises up from the dry bushland plains, forming a 400 meter tall ridge with gaps. Pass through a gap and a new ridge appears, and another one behind it. In between are dry valleys. It is winter now and there has been no rain since early autumn: the rivers have dried up. After…
A couple of weeks ago we got an email from one of our readers who is currently studying how to make ceramics and porcelain in Iceland. She was wondering about what ashes might give the best colours. I am not the best geologist around, and instead concentrate on the squiggly stuff on seismometers and bouncing…
”A Hall she saw standing far from the sun, on Dead Body Shore. With the doors facing North, Venom drops, In through the roof vent. For the walls are woven Of Serpents spines.” Völuspá, Níðhöggr First Stanza. I come from the North, and in our traditions and old religious motifs, we have always known…
Guest post by Tallis My father and I disagree on a lot of things from religion, politics, career, and more; One of the things we disagree on is the title of worst geological disaster. I believe that title goes to volcanoes while my father believes it goes to earthquakes. This is actually a fun point…
As the numbers for the Hunga Tonga eruption continues to come in it is becoming ever clearer that something truly momentous happened, something not seen or heard in 139 years. With a columnar height of 55 kilometres, an explosive pressure wave travelling several laps around the planet, forming a medium sized deadly tsunami, gouging out…
As more information comes in, it is time for a brief update, and for a theory on why the eruption of Hunga Tonga was so destructive for what was, after all, a fairly small volcano. The death toll of the tsunami at the moment stands at five, three at Tonga and two in Peru. There…
It seemed to come out of nowhere. In the midst of a quiet interlude, after the hugely damaging La Palma had ended, when the hugely touristic eruption at Fagradalsfjall failed to re-appear, and the hugely underwatched eruption at Kilauea continued to be underwatched, whilst we were waiting for Reykjanes (which some had predicted to recur…
