What makes a volcano go bang? The Grenadines, Lesser Antilles

Originally posted the Travelling Geologist blog – 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, […]

Science Snap (#33): Earth Science Week

Earth Science Week is an international initiative to promote the great work that goes on in the geoscience community. It encompasses a huge range of topics; from dinosaurs to glaciers, and volcanoes to meteorites. There’s something for everybody. For an overview of how geoscience can have a positive influence on local communities and save lives, […]

Supervisor profile #4: Dr Frances Cooper

Dr Frances Cooper BHP Billiton Lecturer PhD (2008) “Exhumation of the northern Snake Range metamorphic core complex, Nevada” 1) The Twitter challenge: Describe your PhD in 140 characters (if you can remember it) I tested different models for how the metamorphic rocks of the northern Snake Range were brought to the surface from the middle-lower […]

What’s up in Bolivia?

Originally posted on the EGU blog network To many, Bolivia is just an unassuming landlocked country in South America, perhaps most famous for its coca tea obsession and ‘gap yah’ alpaca wool sweaters. But to a number of enthused volcanologists it is a near-perfect playground. In the southwest of the country, sitting at 6008 m […]

Science Snap (#11): The Stiperstones

Originally posted on the EGU blog network. Image reproduced with the kind permission of @ShropshireWalks The Stiperstones is a famous geological landmark in Shropshire, a county known for its geological diversity. Rising majestically out of the heather and bracken-draped hills, the Stiperstones Quartzite forms jagged tors up to 20m high, features visible on the skyline […]

Supervisor profile #3: Dr Matt Watson

Dr Matt Watson Senior Lecturer in Natural Hazards PhD (2000) “Remote Sensing of Tropospheric Volcanic Plumes” 1) The Twitter challenge: Describe your PhD in 140 characters (if you can remember it) I used ground- and satellite-based data to quantify volcanic emissions in order to look at volcanic plumbing systems and plume chemistry.

An ode to metamorphism

Originally posted on the EGU blog network On finding out my ‘profession’, there’s one fact that people proudly announce to me on a regular basis: “I know the three rock types: sedimentary, igneous and metamorphic!”. What usually emerges from deeper probing is that most people are comfortable with the concept of sediments and magma, but […]

Science Snap (8): White Island erupts!

Originally posted on the EGU blog network White Island is a small volcano roughly 30 miles off the coast of the Bay of Plenty in New Zealand. It is part of the Taupo Volcanic Zone, which is also home to the impressive Lake Taupo, a flooded caldera that formed in an eruption (a ‘super-eruption’ if you […]

Science snap (7): Thrusting under our noses

Originally posted on the EGU blog network As Earth Science researchers, we are extremely fortunate that fieldwork often necessitates trips to exotic and far-flung places. But sometimes we are guilty of ignoring the riches right on our doorstep. In Bristol, perhaps our greatest geological asset is the Avon Gorge. At the end of the Last […]
