In response to the growing concerns over the COVID-19 epidemic, EGU has cancelled the physical General Assembly in Vienna and will instead host EGU 2020: Sharing Geoscience Online (#shareEGU20), a week-long series of online activities during which attendees can remotely interact, discuss and share research. With the virtual GA looming in less than a week, it’s time for all attendees to finis ...[Read More]

We are all studying geodynamics, but what does that really mean? Do we limit ourselves to the mantle? The lithosphere? The equations we solve? In this Wit & Wisdom post, Colin Hardy, PhD student in fluid dynamics at the University of Leeds, United Kingdom, makes his case for an often forgotten boundary condition of mantle geodynamicists: the core. Let us start with the basics and break down th ...[Read More]

Can plume-lithosphere interaction initiate a modern subduction zone?

Editorial team 1 April 15, 2020

This week in News & Views, dr. Marzieh Baes from GFZ Potsdam introduces us to the mechanisms behind subduction initiation. Moreover, she discusses the different types of subduction initiation in reaction to plume-lithosphere interaction that she observed in her recent 3-d numerical modelling study. Possible scenarios of subduction initiation According to plate tectonics, oceanic plates are for ...[Read More]

This week on the GD Blog we are taking a magical geodynamicist’s mystery tour to our planet’s Moon thanks to Tobias Rolf, Researcher at the Centre for Earth Evolution and Dynamics (CEED) at the University of Oslo, Norway (currently a Visiting Researcher at the Institute of Geophysics at the University of Münster, Germany). Imagine you are orbiting the Earth at an altitude of a few hun ...[Read More]
