M stands for magma: the Socorro cover-up

The mountain got its name in 1911 when students of the local university, named New Mexico School of Mines, climbed up the hill and painted a 50 meter tall letter ‘M’ near the summit. Other Mines schools had their letter, so why not Socorro? And of course it had to be bigger than the other…

Korean volcanics: the magic of Jeju island

Some nations seem decidedly unvolcanic. They lack the geology and the temperament for eruptions. Take Norway – a no-nonsense nation which prefers a bit of solitude and does not go for attention grabbing. A search for Norwegian volcanoes does come up with some good examples, but these are distant islands which Norway acquired accidentally. Of…

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…

Iceland’s eruptions since 1900

In 1900, Iceland was a very different country. It wasn’t a country, for one thing. Although Iceland had been granted self-rule, it was still a part of Denmark and the local leaders were largely Danish-educated. There was still a Danish governor. The position (not the governor) was terminated in 1904. On Dec 1, 1918 the…

White Island

The Bay of Plenty is an evocative name. The Bay is sandwiched between the two northerly peninsulas of The North Island. The name includes the adjacent land region, so this is a Bay you can live in. The geyser of Rotorua is world-renowned. So are the adjacent Taupo volcanoes, although not quite as widely publicised.…

End of times and volcanic fertilizer

As I was flying over Ol Doinyo Lengai I contemplated that it is the largest fertilizer factory on the planet. It is the prime cause of the massive herds of herbivores trekking across the inner parts of Africa. The ash from the volcano super-charges the grass with nutrients and makes it the best animal-feed on…

Kilauea eruptions

Two VC readers, mjf and Turtlebirdman, contributed lists of historical and slightly pre-historical eruptions of Kilauea. They are worth putting into a post and that is what we have done. We assumed that the second list made use of the first, and used that. It is worth pointing out that an eruption is a failed…

The other Hawaii: observing Haleakala

For a Kilauea update, see the bottom of the post Astronomy is a dangerous science. It is not just the fact that astronomers love to blow things up. Exploding stars are their bread and butter. For a bit of adventure, they collide black holes. And who else would start the history of everything with a…

The Art of Fracking a Volcano II

In this part of the series I will take a look at the risks of harvesting geothermal energy. Let me begin with stating that so far there has been no large accident caused by harvesting geothermal energy. On the other hand, there is no such thing as totally safe ways to harvest energy. We all…
