New Insights into Plume Buoyancy Fluxes and Dynamic Topography from Numerical Modelling

New Insights into Plume Buoyancy Fluxes and Dynamic Topography from Numerical Modelling

Figure 1. Illustration of the hotspot swell and plume buoyancy flux. White dashed line shows the original seafloor topography due to half-space cooling. Dark green line represents the surface dynamic topography caused by the dynamic uplift of the plume. One of the main surface expressions of dynamic topography are hotpot swells formed by mantle plumes. In this week’s post, Ziqi Ma, PhD candi ...[Read More]

Queer Quarterly: Allyship in the LGBTQIA+ community – what it is, how you can help

Queer Quarterly: Allyship in the LGBTQIA+ community – what it is, how you can help

Queer Quarterly is the blog series of the EGU pride group, a LGBTQIA+ team of geoscientists engaged to uphold and improve the rights of the community in the EGU organization. This week’s post is dedicated to allyship: how people outside of the community can support our efforts. The term LGBTQIA+ is the abbreviation for Lesbian, Gay, Bisexual, Transgender, Queer, Intersex, and Asexual. The addition ...[Read More]

How Hot our Moon Can Get: Mapping Radioactive Elements and Thermal State of the Lunar Interior

How Hot our Moon Can Get: Mapping Radioactive Elements and Thermal State of the Lunar Interior

Geochemists and geophysicists, even with their favorite tools, have often scratched their heads while probing Earth’s deep interior—one  can only imagine the challenges while applying those techniques to the Moon! This week in News & Views, Arkadeep Roy, a PhD candidate from the University of Arizona demonstrates how the intersection of experimental petrology, geochemistry, and geophysic ...[Read More]

A New Look at the Rheology of Deep Subduction Zones

A New Look at the Rheology of Deep Subduction Zones

Subduction zones are dynamic regions where intense geological processes like earthquakes, volcanic eruptions, and the recycling of oceanic crust are constantly at play. A key factor that influences the behavior of these zones is *interface rheology*—the strength and viscosity of the boundary (the interface) between the subducting and overriding plates. Understanding this interface is crucial for i ...[Read More]
