Photograph of Kīlauea’s summit, Halema’uma’u Crater, partway through the 2018 eruption. The seismic events at the summit and associated eruptive activity greatly changed the structure of the summit and surrounding region.

Both earthquakes and research project directions can be hard to predict. This week Becky Fildes, a graduate student at UC Davis, takes us on a journey of how she came to study earthquake behavior in Hawaii during an active volcanic eruption and how our understanding of caldera collapses can be further improved. In my first year of graduate school in 2017, I had started studying earthquake statisti ...[Read More]

Paleogeography and the Northern Hemisphere Oceanic Gateways

Eivind Straume a Postdoctoral fellow at the Department of Geological Sciences within the Jackson School of Geosciences explores how the opening and closing ocean gateways have influenced the Earth’s climate in the past.   Changes in Earth’s geography due to tectonic plate motions and mantle convection influence climate evolution on geological timescales. Over millions of years, continen ...[Read More]

Sliding across the Solar System – The missing origins of gigantic landslides

Landslides can be impressively huge and fast and can occur on all sorts of places including asteroids, rocky moons and Mars! Giulia Magnarini Post Doctoral Researcher at the Natural History Museum in London writes all about these gigantic landslides and the clues they could hold into the martian past! Gigantic landslides are ubiquitous in our solar system. Indeed, Earth, Mars, Mercury, Venus, aste ...[Read More]

Deccan volcanism is one of the landmark events in India’s geodynamical history. Yet, its origin is still under debate regarding its association with the Réunion plume.  In this week’s news and views, Ayanangshu Das, a PhD student at the Indian Institute of Science Education and Research (IISER), Bhopal, explains their recent study to understand the emplacement mechanism by observing the magm ...[Read More]
