London VAAC Calling

Lately there has been a bit of discussion about Flight Level Ash Advisories and how people interpret them visavi actual columnal height. Some have been disappointed when it has turned out that the advisories have been up to 3 times as high as the confirmed numbers released by the various agencies at a later stage.…

Holohraun Five Years Later

A guest post from Salting I visited Iceland many times in the past to meet friends and take a day off on my way between Europa and US. In summer 2011 I made an extra-long stop and visited a glacier to better understand the forces that shaped the coastline around my Swedish home island. Trekking…

Nothing Fancy → Ulawun

  Long time no sea. 😀 Actually, I haven’t gone anywhere and I apologize for the sailor joke. What I really mean is that I haven’t done much other than lurk in and around the comments section. My last actual post was a rehash of an ancient topic that I had covered some time ago…

Greip Expectations

  Part 1 of a Greip Series This week, under the rumblings of Torfajökull, we return to one of our favourite areas within Vatnajökull that is yet to show it’s true hand. Or has it already and is there evidence to support that? Due to some recent activity, Carl has been getting increasingly excited in…

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…

Michio Kaku and the stale dough

Flat earthers believe that the earth is flat, but the rest of us have good reasons to think that we know that it is round. The difference is that they trust in their belief in something, and that we trust the scientific process and the data and theories that it yields. A flat earther stubbornly…

Volcanic Winter. Hypothesis and Candidates

A guest post by Tallis Rockwell No one in the Byzantine empire knew why the sun didn’t shine in 536, why the weather was so cruel. Some thought that this was the day of judgment and angels would descend soon. That year it had snowed heavily in the southern dynasty in China which is the…

Unrest at Laacher See: is it us or the volcano?’

[Guest article by Gijs de Reijke.] Well, the big word is out. The results of a study (‘Deep low-frequency earthquakes reveal ongoing magmatic recharge beneath Laacher See Volcano (Eifel, Germany)’, Hensch et al.) have been published on the 7th of January, pointing out the presence of magmatic movement beneath the East Eifel Volcanic Field, Germany.…

Eruptions to come

Let’s start with a question. Which country do you think has the most frequent volcanic eruptions? Before you read on (or peek below for the answer), take a minute to think about it. You can probably guess that Australia is not a front runner. In fact, only two or three countries readily come to mind.…

And The Woolly-Winner Is…

Thank you to all that voted, we had a great turn out which certainly helps distinguish clear winners and other voting trends. I hope some of you managed to find the time to read up on some of the volcanic features you’d never heard about and gained some insight along the way. So, without further…
