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…

The Woolly Mammoth-Sized Eruption Poll

Following on from Carl’s latest post on some unrest in Iceland, I wanted to gauge public opinion on who they thought was going to make the headlines proper rather than the usual clickbait nonsense from the bile-spouting tabloids. I hope recent misleading headlines haven’t swayed our visitors into voting for their latest scare stories! Try…

The goop and the mudcano

On Wednesday I was asked to look into the possibility that there had been an eruption on the West Coast of Sweden. It was one of those phone calls that are really confusing and making you wonder if it is you, or the rest of the Universe, that has gone utterly bonkers. Since it was…

Making a Map

A quick overview of my current VCMap project, which can currently be found at http://www.volcanocafe.org/vcmap I would like to start off by thanking Spike Page for being the inspiration for this project.  A couple of weeks ago, Spike wrote on Spike’s Facebook page asking for someone to test out a Google Earth file. This file…

Baekdu and how I learned to love the bomb

There is a weird beauty to the blueprints for the Tsar Bomba design by Babayev-Sacharov-Trutnev. Never before, nor after, have a bomb reached that level of engineering perfection. It is to date both the largest, and the cleanest, nuclear device detonated. Compared to the inherently flawed Ulam-Teller design and its derivatives used by the US,…
