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…

Volcano Companion

Volcano companion When I go with you into the world It comes alive in colour and mirth With you I find Vesuvius to travel with you is salubrious In distant past I went alone And found a world in monochrome With you volcanoes come alight The lava flows are burning bright To go with you…

The stones of Stonehenge

The bird struts across the henge as if its owns the place. It is quite a sight itself: large, confident, and long extinct. It was re-introduced here a decade ago but is rarely seen. Great bustards are shy, befitting the fact that they look very edible. This one, for a strange reason, had lost its…

Phantom caldera

Guest post by Tallis. In my previous piece, I went over the process of large caldera forming eruptions and the abundant noise that they would produce but a comment by cbuso5 caught my attention and interest. I have one slight disagreement. I’m not necessarily sure that the signs before a super eruption would be particularly…

The Wandering Earth: mantle in motion

It is nice to live on the crust. It gives a degree of stability which the rest of the Earth lacks. It is not perfect: the quiet can be punctuated by earthquakes or volcanoes, and lacking those there is still the off-chance of a landslip or flood. The atmosphere may also interfere with our lives.…

The Wandering Earth: when rocks flow

The wonder of water The tell-tale sign of the suspension of the laws of physics is someone seen walking on water. The suspension is always temporary – as soon as a second person tries to follow, the laws of physics are re-instated and the person looking for the ‘me too’ experience instead encounters full immersion.…

Intermezzo

Post by Geolurking, based on a repost I have been tasked to revisit something I covered years ago.  And update it with a bit of fresh info.  The original publish date was 20 Feb 2012. The first thing I need to cover, mainly in order to bring every one up to speed… is the compass rose.…

Prelude to Krakatau. III

In Part 1 and Part II we went over the current state of Krakatau and its history over the 300 years before the Big One. Now it is time to find out what caused the Big Bang, whether it is a recurrent offence, and to try our hand at the big question: why is such…
