Originally posted the Travelling Geologist blog – http://www.travelinggeologist.com/2015/05/volcanoes-of-the-grenadines-with-charly-stamper/ The world’s most explosive and dangerous volcanoes are located at destructive plate boundaries. Here, dehydration of the subducting tectonic plate initiates partial melting of the overlying mantle wedge and produces magma (and hence, volcanoes). Lavas erupted from volcanoes at these locations chart a huge variety of evolved compositions, […]
Kick ’em Jenny is a submarine volcano located 8km to the north of the Caribbean island of Grenada. It lies close to the small, uninhabited volcanic islands of Ronde, Diamond, Ill Caille and Les Tantes, though no physical evidence of the volcano is evident from land. At least twelve recorded eruptions have occurred since Kick […]
Originally posted on the EGU blog network Soufrière Saint Vincent is youngest volcanic centre on the Caribbean island of St Vincent. A stratovolcano some 1,230m in height, La Soufrière has erupted five times in the last three hundred years, most notably in 1902 when 1,680 people were killed. The explosive volcanism here is the surface […]
A lot of people think that doing an Earth Science PhD involves looking at rocks. Most of the time they’d be wrong (experimental petrology = making pretend rocks; geochemistry = water; geophysics = computers; palaeontology = colouring in), but just occasionally, I do get to play with the real thing. From sample pick-up to analysis, […]
