Andrew McGonigle featured in National Geographic
National Geographic have been running a series of pieces on the work of Rolex Award Laureates and National Geographic Explorers. Recently they have covered Andrew's work on the development and application of new techniques in volcano monitoring. This piece focuses on new Leverhulme Trust funded work conducted by Andrew, with Tom Pering and Tom Wilkes of the Department of Geography and Italian colleagues from Palermo. In particular, these researchers have pioneered a new inexpensive way of monitoring volcanic gas release on the basis of £20 mobile phone camera sensors. These sensors have been adapted to measure downwelling ultraviolet radiation from the sky, which is partially absorbed in volcanic gas plumes. Camera imagery provides scope for gathering data every few seconds, far faster than possible previously, enabling scientists to probe the inner workings of volcanoes in unprecedented detail. In particular, this is facilitating comparison of measured gas release from the surface, with computational models for gas flow in volcanic conduits, for the first time. By joining together these previously disconnected branches of volcanology, fresh insights are being provided into how underground processes drive the observed activity at the surface.
