The case for an African VAAC 

Welcome to the “Rant Edition of Volcanocafé”, tonights special: Carl Erupts.  For a decade I have talked about the need for increased monitoring of African volcanoes. It is if nothing else, rather ridiculous that the volcanoes in Antarctica are far better monitored than African volcanoes bordered by large cities.  Yesterday this came very close to causing a large disaster with international…

The ballad of Ballareldar: twister in the snow

Volcanoes are nature at its most impressive – and most damaging. The fire and the lava are a deadly alluring combination. Once the flow gets going, it is unstoppable. It may be deflectable: people are currently trying hard to save their road by building a wall. We were wondering, will the wall work? It would…

The ballad of Ballareldar: the boom and the bust

The eruption continues. There is so much hiding behind such an easy sentence. It continues – but always changes. It is not life as we know or understand it is the second most memorable phrase (at least in the paraphrased version) from Star Trek. This eruption is like that. You forget that this is actually…

The ballad of Ballareldar: the dike, the fissure and the fault

This is quite an eruption, with surprises with every new turn of events. It is an unusually tourist-friendly eruption: conveniently located, small, non-damaging (except to the owner of the land) and spectacular. It does appear that not all tourists are as friendly to the virtual tourists, judging from the antics going on in front of…

The Plume of Ballareldar?

To me the part of a volcano that is visibly erupting is the least exciting part. Perhaps a better way of stating it is, that it is only the effect of the cause. This is obviously not true to most people on the planet, so I think I owe everyone an explanation. And that explanation is especially important since we need to look deep into the volcano, to understand its future.   Like most people I can obviously spend hours looking at lava bombs being hurled, and lava slowly filling valleys. But, getting…

The Basel earthquakes

Late in 2020, an M6.4 earthquake struck the town of Petrinja in Croatia. It caused extensive damage in the town and in nearby villages, and 7 people died. Even so, the impact was more limited than it might have been because houses here tend to be well build. It came as a surprise: powerful earthquakes…

A wandering eruption

Since the eruption in Iceland started, some of us have been wondering about other past volcanic events that we could compare it to, in such a search I came up with an Icelandic eruption that I believe might by a good analogue, and no, it’s not the Krafla Fires. Currently some of the characteristics of…

Soufriere a VEI 4

Howdy all. Long Time no Sea… 😀 I am one of your dragons. I lurk around in the back channel conversing with the other Moderators. My claim to fame here on VolcanoCafe is that “I plot stuff.” One topic that we have been kicking around, is just how large is the La Soufriere eruption. Albert…

The Hell Machine

Guest post by Chad As is now abundantly clear, a new eruptive cycle on the Reykjanes Peninsula has begun. While an isolated eruption did happen in the ocean off the end of the peninsula in 1783, there has not been an eruption on land since 1240, today 781 years ago. The eruption ongoing now has…
