Unrest at Torfajökull

  This is just a short piece about mounting unrest along the extension of the Veidivötn Fissure Swarm as it is running through the Torfajökull volcano. Torfajökull has two known magma reservoirs, one on the south east side that is mainly andesite-basalt, and a rhyolite chamber towards the south-west. The current lineament is having the…

Greip: A prequel on instrumentation

This is both an informal start of our series about a promising central proto-volcano, and a story about the problems of sifting through the bewildering number of signals that the instruments yield for us to peruse. Let me start out in the stars. A friend of mine work with SETI, the search for extra-terrestrial signals.…

The Moon and the Moonie

This is a revisit due to something Albert spotted out on the Internet; https://phys.org/news/2018-01-great-earthquakes-affected-moon-phases.html   GeoLurking / April 22, 2012 Part I: The Moon Time and time again, someone bops along with the idea that the Moon or the Sun causes an increase in seismicity. They climb up on their soapbox and thump their chest denouncing the…

The Life Aguatic

We got a letter from one of our readers this week pointing out a seismic series near Agua volcano and Ciudad de Antigua in Guatemala. “I’ve been living in Guatemala for a while, staying in Antigua. On April 27, the area around, and on, Agua volcano started to shake. We felt at least 8 quakes…

Eruptions of Basalt and Rhyolite

Guest post from Tallis Some of the most beautiful of sights on the planet are the remnants of the most violent of scenes; The amazing Yellowstone National park is in place of the world’s most notorious “Super volcano”. As a rational conspiracy theorist, I have to constantly put up with the claims of Yellowstone’s imminent…

Sahara, Scotland

The conifers stand tall, straight. They look old but there are patches where trees have been cut, and there is replanting elsewhere, evidence of tree harvesting. The evergreen forest is popular with tourists. This is in spite of the latitude: there are more northerly places in Scotland, but not many. The climate is not as…

Lava lake to provide green energy

This was the April-1 post for this year. Enjoy! But don’t believe. On the other hand, it is not impossible either and perhaps, one day ? The world is approaching an energy crisis. Oil is due to run out by 2040, and longer-lasting oil shales yield a low quality, heavy oil which is poorly suited…

On the importance of Deep Quacks

Back in early 2011 I was sitting down for a late light evening read of “Lower-crustal earthquakes caused by magma movement beneath Askja volcano on the north Icelandic rift” by Soosalu et al. As I read angels started to sing a glorious hymn as I had an epiphany and my view on how volcanoes operate…

The most erect of volcanoes?

Have you ever wondered about which is the tallest active volcano on the planet? It sounds like a fairly straightforward question. But, as with all simple questions it quickly turns into a quagmire of definitions. The first of the definitions starts out in linguistics, and that is what is the definition of “active”. It turns…

536: apocalypse

The legend of the horsemen of the apocalypse goes back to the first century AD. It is a gripping image, which has transcended cultures. The best-known of the horsemen is Death, riding an ashen-coloured horse. This is the only one given a name in the original. One horseman, riding a black horse, brings famine, making…
