What Can Island Isostasy Tell Us About Hotspot Dynamics?
The Cape Verde Archipelago - the type-example of a hotspot in a stationary plate environment with respect to its melting source - exhibits ubiquitous evidence for quaternary uplift.

What is a plate? We undertake a comprehensive analysis designed to significantly advance our understanding of the structure and evolution of oceanic plates.
Our project will focus on the subduction zone off southern Alaska, which produces large and destructive earthquakes.

Christopher Scholz is being awarded the Harry Fielding Reid Medal for his pioneering work in rock mechanics and his skill at communicating earthquake science. The Seismological Society of America cites Scholz’s wide range of contributions over a nearly 50-year career.
In their quest to unravel the physical and chemical processes controlling volcanic eruptions, Einat Lev and colleagues headed to South America and the volcanoes of Chile. She writes about the trip and what they hope to learn from their work, and shares video from their drone flights over the lava flows.
Deep beneath Alaska’s Aleutian Islands, down where the pressure and temperatures have become so high that rock starts to flow, new continental crust is being born. Scientists have long believed that continental crust forms in volcanic arcs – they know the magma brought up in the arcs’ volcanoes is geochemically very similar to continental crust. The lingering question has been how exactly that happens. While the magma that reaches the surface is similar to continental crust, the lower crust beneath volcanic arcs is quite different from the lower half of continental crust.
Over the last six years, seismologists Göran Ekström and Colin Stark have been perfecting a technique for picking out the seismic signature of large landslides from the stream of seismic data from earthquakes and other activity around the world. The details they are able to extract could one day help governments sound tsunami warnings, help rescuers find landslide-struck villages faster, and warn of risks such as landslide-dammed rivers that could soon burst through.
When the most recent eruption of Hawaii’s Kilauea volcano started last June, Melvin Sugimoto at first did not think much of it. Hawaii, where he has lived all his life, is made entirely of hardened lava, and Kilauea, perhaps the world’s most active volcano, has been adding more off and on for the last 300,000 years. “Lava is everywhere, but I never thought in a million years it would come through here,” said Sugimoto, who lives in the small town of Pahoa.
Earth’s magnetic field has been getting weaker, leading some scientists to think that it might be about to flip, but the field may simply be coming down from an abnormally high intensity rather than approaching a reversal, scientists write in a new paper published online this week in the Proceedings of the National Academy of Sciences.
Scientists at Columbia University's Lamont-Doherty Earth Observatory and the University of Illinois at Urbana-Champaign have ended a nine-year debate over whether the Earth's inner core is undergoing changes that can be detected on a human timescale.
