The legacy of Lanzarote

Lanzarote ranks as one of the most obviously volcanic places on the planet. The island is covered with craters, cones and lava fields. The dry and frost-free climate means that volcanic features weather only slowly, and vegetation has had a hard time gaining any meaningful foothold on the land. The cones and lava go back…

Volcanoes of the North: the fire in the ice

A freezer provides storage. And a deep freezer gives deep storage. You can’t go deeper than an original ice-age glacier. In Greenland, those glaciers are still there, being so tall that the top has remained in deep freeze even though the ice age is a distant memory. In this cryogenic environment, that frozen memory is…

Volcano on the rocks

People need mementoes. They are small things (normally) with little intrinsic value (often), but which carries a memory which is far more valuable to the owner than the item is in itself. It can be a bit of jewelry, a cup, or a chair, or even a pebble. Or it can be one of many…

The 3 x 4½ km summit caldera of Mount Katmai, Alaska, that formed after the 1912 VEI 6 Novarupta eruption (Wiki)

Calderas

This is a re-post that has been re-posted before. But we attract new readers and sometimes it is worth republishing something. Especially since this is about Icelandic (and other) calderas, something that has been raised in the comments recently. This post was originally written during the Holuhraun eruption and associated Bardarbunga collapse, and you will…

Typing eruptions

Guest post from Tallis Various types of explosive eruptions have been prevalent across history, after all not all volcanoes are the same. However some volcanoes have something in common with another whether it be a magma type, location, setup, age, or size. Allow to define what I mean by “Model”. My strongest science is not…

Tambora, the lost summer and the hobby horse

Morn came and went – and came, and brought no day Lord Byron, Darkness, 1816 The world has changed. It is not something we normally notice – change is slow and memory surprisingly selective. Nothing has altered but everything’s changed, as the song says, paraphrasing Jean-Paul Sartre. We have little idea of how our parents…

Power of the past: 25 super eruptions – continued

The VC list of 25 super eruptions – continued In our quest for major eruptions, we are continuing our journey around the world, moving north from Indonesia. Kyushu, Japan Japan’s southernmost main island is volcanically highly active. Past explosions have left large calderas, separated into two groups. In the centre of Kyushu is Aso, and…

Power of the past: a compilation of 25 super eruptions

The battle of Stalingrad was among the bloodiest and most horrific of the second world war. During the cold winter of December 1942, the Commissar of Stalingrad organised open-air party meetings for local artists and musicians to encourage the exhausted and hungry soldiers. One of those musicians was the violinist Mikhail Goldstein. On New Year’s…

The mystery of The Mysterious Island

If there ever was a patron saint of Volcanocafé it would be the author Jules Verne. When he was not inventing cadres of literary genres, he was quite obsessed with volcanoes. When he was not writing he spent his time reading about volcanoes (and other things scientific). And quite often he combined his interests of…
