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 ki ...[Read More]
Friday Photo (100): Road Disappearing Under Wind-Blown Sand
Maintaining roads in remote mountainous areas is no easy task, especially in the face of active geological processes. Here wind blown sand is covering a road, making it impassable. (c) Geology for Global Development 2013
Friday Photo (99) – Fitting Life Around Geology
Geology exerts a strong control on landscape, agriculture and infrastructure in Ladakh, India. Here the road (left hand side) is cut into softer glacial moraines, rather than the igneous and metamorphic bedrock. Agriculture is centered on alluvial material from a river predominantly fed by glacial meltwater. (c) Geology for Global Development 2013
Friday Photo (98) – Hydroelectric Energy in Ladakh
Hydroelectric power plants are being developed across the Himalayas. Here, a small-scale system is used to store energy during times of peak supply from other sources, and deliver energy during times of peak demand. This system relies on the shuttling of river water (seen in the background) between different elevations. (c) Geology for Global Development 2013
