Crisis on Ioto

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 rusting hulks of ships, sunk in the long battle. And that…

A geomorphology dive into caldera systems (calderas on the surface)

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 volcanoes. It’s nothing new that calderas generate all sorts of admiration…

Ibu, an overlooked caldera

Indonesia is a country of volcanoes. An impressive amount of subduction-related volcanoes. The country features four different volcanic arcs, chains of volcanoes above subducting oceanic plates. The most important one is the Sunda Arc, home to way too many famous volcanoes like Toba, Krakatau, Galunggung, Merapi, Semeru, Bromo, Kawah Ijen, Batur, Agung, Rinjani, or Tambora.…

Gran Canaria

The Canary Islands are 7 volcanic islands off the coast of Africa. They are but the peaks of several massive shield volcanoes that have grown from the bottom of the ocean over the past 30 million years. The islands are older in the east, and younger in the west. Six out of seven are still…

Deception Island: the phoenix rises

Volcanoes can hide themselves in clear sight. We may see a rugged hill or a lake, but may not recognize the lurking danger. A volcano that lacks a conical shape can hide its nature from us. Volcanoes are deceptive by nature. That cone with the steam plume at the top may look friendly, but it…

Taupo Tapping Away

Taupo is one of those volcanoes I do not like to write about in Volcanocafé. It is one thing to write a historical retrospect of what it has done in yon olden days, and something completely different when it is doing something interesting. The reason is simple, Taupo is one of those volcanoes that have…

Rome’s world’s weirdest caldera

Italy is a fascinating country, and when it comes to volcanology, Italy has been arguably the most influential location in the planet. The first ever detailed description of a volcanic eruption came from Pliny the Younger writing about the eruption of Vesuvius in 79 AD. Vesuvius was also the first volcano to be watched over…

Islands in the stream

In the last few weeks, I have been unusually busy with things decidedly non-volcanic as the world turned quite a bit darker. Regardless I noticed that there were quite a few things going on in the volcanic part of the news, but that did not for natural reasons end up as big news items. One…

The Current Volcanic State of Affairs

I am taking this opportunity to look at 5 volcanoes that at least I find interesting. I am doing this out of the perspective of the life-curve of an eruption. I find this perspective to be interesting, and I think that it is something that would be both entertaining and informative for our dear readers.…
