I take it where I left it in my last post. Using volcanic signals (mainly sulfate spikes) in the Greenland and Antarctica ice cores, I listed the most powerful explosive eruptions between the years 1500 and 1900: Largest explosive eruptions, from 1900 to…

Today is 270 years since the destruction of Lisbon. The earthquake of All Saints day 1755 in Lisbon changed a nation and is still remembered across the continent. Hence a republication of our 2016 post on this event. A few words on the effect on Scotland…

A fun question: which are the southernmost, most equatorial and northernmost volcanoes in the world? We need to add two provisos here, otherwise this question is impossible to answer: the volcano should be on land (sub-aerial, not sub-marine), and it…

After the recent developments of Iwo-Jima volcano, I’ve grown interested in whether submarine calderas are capable, or not, of producing substantial stratospheric sulfur injections, also in the effects and frequency of these injections, and eventually, as…

The Earth is full of riches. Once people discovered the importance of metals, they quickly found out where to get them from. The first mined metal may have been copper. When mixed with tin, this formed bronze, malleable but strong. Mines were dug and…

Introduction (Albert) Iwo Jima is famous. The battle between the US and Japanese forces are well remembered – by both sides. Before the war, about 1000 people lived here. After the war, none. There is a military base only. The beaches are filled with…

The North Sea and the Zuidwal volcano

We recently published a post on the Zuidwal volcano, found buried in the Netherlands and becoming a google sensation – google is still working on removing all the made-up images. But in spite of google, there is a real story behind this volcano. It is the…

Figuring out the eruption history of Afar volcanoes is taking longer than I expected, so in the meantime, I will have to post about other topics. And lately, one that has been present in my volcano discussions, here and elsewhere, has been about caldera…

The censured volcano

The only truly dead volcanoes are the ones whose existence we have forgotten about. The Netherlands is not known for its volcanoes. There is a volcano with a Dutch name: Beerenberg, an impressive stratovolcano on Jan Mayen, but the volcano itself is in…

The Cerro Negro Problem

Over the past 6 years I’ve watched Chiles-Cerro Negro go through 4 different phases of unrest. Like a toxic lover, no matter how much I try, I can’t shake this volcano. I honestly thought I was going somewhere with Grimsvotn and Iwo-Jima but no. Grimsvotn…
