Continental rifts are a striking manifestation of the forces at work in the Earth’s interior and are often associated with volcanic activity. Contrary to intuition, volcanism is not confined to rift grabens, but migrates as the rifts evolve. How and why this happens is still not clear. This week, Gaetano Ferrante from Rice University, Houston (USA) will share his research with us, showing ho ...[Read More]

In this week’s blog, Garima Shukla, ECS representative of the Geodynamics Division and PhD student at the Indian Institute of Science Education and Research, Bhopal, India, working with Dr. Jyotirmoy Mallik, discusses her research involving fieldwork and statistical calculations. Her research also delves into rock magnetism and palaeomagnetism to unravel the longstanding enigmas surrounding ...[Read More]

Two phase or not two phase

In this week’s blog Shi Joyce Sim from Georgia Institute of Technology shares the underlying science behind two-phase flow dynamics.   A talk at the Lunar and Planetary Science Conference in March got me thinking. Basically, the presenter described how boundary layers grow over time, a phenomenon that cannot be captured using one dimensional models and necessitates modeling in higher dimensi ...[Read More]

Biogeodynamics – Let’s model the entire world!

All models are wrong, but some are useful – we all have heard this quote. But it raises several questions (including but not limited to) – What would a model of the entire world look like? Can you couple geodynamical models with climate and biological evolution models? Would these models be useful? In this week’s blog post, Timothy Gray, a PhD student from ETH Zürich is looking for ans ...[Read More]
