Much of our world is in hiding. It lies below the surface of the oceans and is largely invisible to us, a Maria Incognito. It is a hostile world: we are creatures of the solid ground, who long left the seas behind and cannot return. But more of this forbidden world is being uncovered, by…
I’ve been tracking Chiles-Cerro Negro for almost 10 years now and it’s been an interesting ride to say the least, full of great highs and terrible lows. My odd relationship with this volcano is going to be on pause and I will be exploring other volcanoes. As such this will be the final article on…
We, humans, are ingenious at finding smart ways to do the impossible. Regarding volcanic eruptions scientists have found a way of figuring out when large volcanic eruptions occurred with incredible precision, large explosive eruptions from anywhere in the world, by looking at ice none less, who would have guessed that? Combined with high-precision geochemical studies…
Sometimes a project becomes remarkable. Some years ago we started thinking about what to do with the James Webb Space Telescope, whenever it would become available. An idea was developed and we worked out what kind of data would be needed. It turned out to be feasible, so we proposed it. That is harder than…
Greetings. This article has a long history of not being written. It originated a few years ago when the 2018 lower Puna eruption was on going. Before I start, let me vent. IN MY OPINION, there is no such thing as a “Supervolcano”. That term was popularised by the BBC for their disaster movie of…
It is hard to remember what Iceland was like three years ago. At that time, most (or all) eruptions were in the eastern volcanic zone, from Katla (and friends) to Krafla. (Ok, one can argue about the precise borders. Grimsvotn was about to erupt. The Thorbjorn swarm had happened and an eruption at Reykjanes was…
After our ‘quantum Katla’ post, it is now time to return to the real Katla. For in the real world, Katla has been showing unusually strong shaking. It turned out that Henrik had already done much of the work for us. Here is a resurrected post from the dungeons of 2012 where young Henrik keeps…
In view of the current tectonic activity at Katla, we offer our readers a repost. Katla has a reputation among some of the disaster crowd, and any shaking there can lead to predictions of worldwide doom. It sometimes seems like a Yellowstone on ice. Hence this story. Physiology has a dog; physics has a cat.…
My own expedition into Etna’s center Jesper Sandberg Introduction I have always been addicted to volcanoes, and that addiction has resulted in many volcanic visits over my last 27 years of life, and I have indeed made many volcanic visits. The highpoint of that was seeing the live lava flows at Kilauea: of course Kilauea…
The largest eruption of the 21st century happened at sea. And it wasn’t Hunga Tonga. The Comoro islands form a forgotten archipelago, somewhere between Africa and Madagascar with about 200 kilometer of open ocean on either side. On the African side the nearest land is the northern end of Mozambique, close to the border with…
