Escape

Who doesn’t dream of escape? Perhaps you have a mind-numbing job, a repressive social environment, or a damp and cold house. It may be an escape in (and from) a computer game, trying to reach the exit while being chased by your real-time friends becoming virtual enemies. Sometimes we need to escape from a dream,…

The Ballad of Ballareldur: Explosions in the night

Over the past weeks, the Fagradalsfjall has settled into in almost predictable routine. There are regular cycles of eruptions and interruptions. During the interruption, the tremor goes quiet. Nothing is shaking or moving on the drum plots. Over several hours, there is a slow build-up of the tremor. Lava begins to return to the crater…

Volcanoes of the North: the fire in the ice

A freezer provides storage. And a deep freezer gives deep storage. You can’t go deeper than an original ice-age glacier. In Greenland, those glaciers are still there, being so tall that the top has remained in deep freeze even though the ice age is a distant memory. In this cryogenic environment, that frozen memory is…

The Great Alaska earthquake of 2021

Alaska can be a shaky place. Earlier this week, at 10:15pm local time on Wednesday, there was an M8.2 earthquake in the region. It was the largest earthquake on Earth since the M8.3 in Chile in 2015. Let’s award the US the gold olympic medal for earthquaking (after all, the Chilean winner was from the…

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…

Ring dyke formation on Taal?

Lately Taal volcano has been showing unsettling signs of a possible imminent eruption, including high sulphur dioxide emissions, small steam-driven explosions, tremor, and somewhat surprisingly, deflation. I think that this is no conventional magma intrusion but rather a very rare type. First of all I should briefly review what happened in 2020.   The events…

Taal in water

Long time no sea… 😀  For those of you not familiar with me, I am one of the “dragons” that lurk behind the scenes.  My main claim to fame is that “I plot stuff.”  I also on occasion have written filler articles when needed.    This isn’t one of those articles… but since I am a…

The changing faces of Fagradalsfjall: fizz, bubbles and slugs

We have had quite a ride. The eruption began unseen, on March 19. The new fissure opened on April 5, after the initial double cone had begun to wane. The new fissures sprouted a series of cones, mostly twinned. By May, all twins had exterminated one of the siblings, and the survivors had battled for…

Kilauea II: Roots of the Hawaiian Islands

In my previous article, here, I discussed how Kilauea and Mauna Loa volcanoes are connected to each other through the Pahala Swarm. Now I have to deal with a confrontation of theories that is inevitable. There is a classical model of how Hawaii works. It is all about the mantle plume. The classical view establishes…
