As part of our Blog Competition 2013 we asked you to submit your favourite photos of geoscience in action. Rick Wall, who has just completed a PhD in volcanology at UCL, entered this image from his field work in Alaska. The entry was highly commended by our judging panel.
The photo shows the location of the 1912 Novarupta eruption in Katmai, Alaska. This eruption produced about ∼30 cubic kilometres of material, part of which created the Valley of Ten Thousand Smokes by infilling the surrounding topography.
The winning entry in our image competition, from David Litchfield, has been transformed into a postcard and will be unveiled at our conference on Wednesday, 23rd October.
