With the EGU General Assembly (GA) less than a month away, attendees should start planning their schedules to get the most out of the week. In today’s blog, Geodynamics (GD) Division Early Career Scientist (ECS) representative Garima Shukla highlights the GD Division’s networking events and provides an overview of key events at the GA. Networking Events: Geodynamics Division What: ECS ...[Read More]
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]
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]
What’s the role of hotspot and oceanic transform faults at ultraslow spreading ridge?
Mid-ocean ridges (MOR) and hotspots are two types of magmatic activity occurring in the ocean. The MORs are typically associated with another tectonic feature—oceanic transform faults. While numerous studies have focused on the interactions within MORs, hotspots, and transform faults, there has been limited research on cases where a hotspot and a transform fault are located at the same end ...[Read More]
