Imaggeo on Mondays: The Chalk Cliffs of Étretat

Étretat is a coastal region in northern France, well known for its stunning geological landscape. Particularly the headland you see here. Headland erosion is perhaps one of the best known processes in coastal erosion, where a crack in the headland is opened and enlarged by hydraulic abrasion. Continued wave action causes the widened crack or cave to break through the headland and form an arch. As ...[Read More]

Geosciences Column: Perfecting Palaeogeographic Reconstructions

We model the changes in the geographic location of continents via paleogeographic reconstructions. However, the current methodology for generating these reconstructions is not without problems! Publication of palaeogeographic reconstructions is scarce, probably resulting from the difficulties associated with generating them. Conventional reconstructions are presented as static maps which have poor ...[Read More]

Communicating Climate Change

The UK House of Commons Science and Technology Select Committee has recently launched an inquiry entitled “Climate Change: public understanding and its policy implications”, which is due to address the issue of communicating climate change research. This inquiry was raised following a recent surge in climate change scepticism and a diminishing public concern regarding its effects, with ...[Read More]

Imaggeo on Mondays: Explosions in the Sky

Suwanosejima, which lies within the Ryukyu Islands, is one of Japan’s most active volcanoes, erupting almost continuously between the 1950s and mid 1990s. It has two active craters, the central Otake crater and the Bunka crater, to the southwest. While the frequency of these eruptions has declined, the volcano remains active, with strombolian and vulcanian type eruptions occurring every 2 to 4 wee ...[Read More]
