The Snowdon volcano

One from the archives (from 2013, with small additions). Karen Z on Snowdonia The British Isles have an extreme diversity of geology. Travel 20 miles from just about anywhere, and you’ll find a region with a very different history. Almost every geological division of time left a mark somewhere here. I live on ice age…

The Great Whin Sill

The results of a study (‘Deep low-frequency earthquakes reveal ongoing magmatic recharge beneath Laacher See Volcano (Eifel, Germany)’, Hensch et al.) have been published on the 7th of January, pointing out the presence of magmatic movement beneath the East Eifel Volcanic Field, Germany.…

The Kazbek disaster: a cryoclastic debris flow

What makes a volcano dangerous? Clearly, the severity of any eruption plays a role. So does the presence of people nearby. But it is not always the best known volcanoes that are the most dangerous. Tseax is hardly world-renowned, but it caused a major volcanic disaster in Canada. And sometimes a volcano can be dangerous…
