Sand dunes can ‘communicate’ with each other

Even though they are inanimate objects, sand dunes can ‘communicate’ with each other. A team from the University of Cambridge has found that as they move, sand dunes interact with and repel their downstream neighbours. Using an experimental dune ‘racetrack’, the researchers observed that two identical dunes start out close together, but over time they … Read more

‘Melting rock’ models predict mechanical origins of earthquakes

Engineers at Duke University have devised a model that can predict the early mechanical behaviors and origins of an earthquake in multiple types of rock. The model provides new insights into unobservable phenomena that take place miles beneath the Earth’s surface under incredible pressures and temperatures, and could help researchers better predict earthquakes — or … Read more

Formation of a huge underwater volcano offshore the Comoros

A new submarine volcano was formed off the island of Mayotte in the Indian Ocean in 2018. This was shown by an oceanographic campaign in May 2019. Now an international team led by the scientist Simone Cesca from the German GeoForschungsZentrum GFZ is illuminating the processes deep inside the earth before and during the formation … Read more

UCI-led team releases high-precision map of Antarctic ice sheet bed topography

A University of California, Irvine-led team of glaciologists has unveiled the most accurate portrait yet of the contours of the land beneath Antarctica’s ice sheet – and, by doing so, has helped identify which regions of the continent are going to be more, or less, vulnerable to future climate warming. Highly anticipated by the global … Read more
