The Urban Volcano

Guest post from Tallis If you were to ask a volcano enthusiast “What is the most dangerous volcano on the planet?” you’d get a range of answers. From a novice, Yellowstone, from someone who only knows of American calderas, the Long Valley caldera. The generic but not wrong, Vesuvius, Mt Rainier, Campi flegrei, Paektu, Santorini,…

The Hotness of Grimsvötn

As far as volcanoes go, we like to think of them as immutable giants that rarely if ever change. We like to see Grimsvötn as a glacier covered giant of a volcano, that almost always produce moderate ashy eruptions, that are relatively speaking short-lived. Yes, once upon a blue moon it will do something big,…

Nishinoshima – The Seminal Eruption

Nishinoshima is in many ways the perfect volcano, it is constantly doing firsts, and spectacular and unusual things. Normally volcanologists would gather nearby and play lip-banjo at its antics. But since it is far out into the ocean and is so inaccessible most miss this beauty of a beast. In November and December of 2013,…

Calling All Volcanians

Guest post from Tallis An Appeal for Advice I thought I was finished with Chiles-Cerro Negro, I have already written two articles on this volcano before detailing my thoughts, issues, concerns, and scenarios. Chiles-Cerro Negro is a volcano that has been restless for almost 7 years now, it has had large swarms and other signs…

The little volcano that could

The little part here is highly metaphorical, or perhaps I should say challenged in regards of prominence. The volcano in question is once more Nishinoshima. Back in 2013 when it rumbled back to life it was all the rave, but nowadays I bet that even most volcano afficionados have missed the return of the ocean…

Þorbjörn’s Tormented Tribulations

As Þorbjörn rumbles on it seems ever likelier that it will erupt. So, to explain what is happening I decided to pull out all the stops and produce a more definitive article explaining the news and a possible future now that Albert has put things into context. So, without further ado, I would like to…

Volcanic alert at Þorbjörn Volcano

The Icelandic Met Office has released an Official Bulletin about the possibility for an upcoming eruption at Þorbjörn on the Reykjanes Peninsula in Iceland. Þorbjörn belongs to a class of volcanoes that I normally like to call Unknownabunga, one of all of those volcanic features in Iceland that pretty much nobody knows anything about, until…

A Taal Tale

Sometimes, a volcano is nothing more than a hole in the ground. There are beautiful, though deeply eroded, cone volcanoes around Taal: Mount Banahaw, Mount Mariveles, Mount Natib – especially the latter also has a large caldera. But Taal is not like that. It is a lake, with only a little cone sticking out. The…

Taal eruption update

In my previous article I wrote that Taal most likely would not continue to erupt for a long period of time, based on the previous history of the volcano. Obviously Taal decided to go for something not recorded in the historic annals. It is therefore time to take a deeper look at what is going…

Taal Update – Ongoing Intrusion

Guest post from Héctor (DustDevil). There will be a further update either later today or tomorrow as events have changed since Héctor wrote this post. The Main Crater of Taal seems to have calmed down, doesn’t it? However fissures are breaking the ground apart, the river dries, Lake Taal falls and strong earthquakes keep coming.…
