Lahars at Volcan de Fuego, Guatemala. This image captures a lahar [mudflow] deposit close to Volcan de Fuego. These deposits are formed when rain mobilises ash and pyroclastic material on the volcano to form a fast moving, powerful mudflow with the ability to transport material including large boulders. As the energy dissipates, the sediment is deposited as we see above. Difficult to see in this i ...[Read More]

The known unknowns – the outstanding 49 questions in Earth Sciences (Part IV)
We are coming to the end of the known unknowns series and so far we have explored issues which mainly affect the inner workings of our planet. Today we’ll take a look at the surface expression of the geological processes which shape the Earth. Topography significantly affects our daily life and is formed via an interplay between primarily tectonics and climate, but it also affected by biological, ...[Read More]
