This is the last part of my article series, and it will be about the most complicated stuff: a look at the behaviour of Nyiragongo’s lava and how fluid it really is. In part three we had a look at how unusual its low silica magma chemistry is, and how this led to the famous…
Introduction In part one I took a close look at the large scale forces that drive volcanism in Africa, at continental rifting in its different stages and the types of magma chemistry that form because of it. I also discussed the origin of the forces that created Nyiragongo and Virunga in the first place. In…
Few people would have heard of Mount Nyiragongo before its current eruption. There are some cities that we know live in the shadow of a volcano. Naples and Vesuvius, Catania and Etna, Seattle and Rainier (although the city itself is unlikely be affected by an eruption), Fuji and Tokyo (with the same proviso). But Nyiragongo…
