Back-arc systems: arguably the most influential tectonic feature in the oceanic domain

Dr. Anouk Beniest, an Assistant Professor in Tectonics at the Vrije Universiteit Amsterdamat, is an interdisciplinary earth scientist, bringing together geology, geophysics and geodynamics to help us understand complex geological problems. Her research revolves predominantly around plate tectonics, with a focus on extensional systems and she has kindly put together this blog post to convince you t ...[Read More]

The Moon is our nearest neighbour but despite its proximity to Earth its two faces are still veiled in mystery! This week PhD student Alice Turner from the University of Oxford explores deep lunar seismicity and what this can (or cannot!) tell us about the Moon’s interior and its near- & far-sides! Outlining the Earth and its Moon with seismicity    Mapping out the locations of earthquak ...[Read More]

Investigating earthquake activity of the 2018 Kīlauea Volcano eruption

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]
