Whole solid-Earth numerical simulation: Towards an understanding of mantle-core interactive dynamics

Whole solid-Earth numerical simulation: Towards an understanding of mantle-core interactive dynamics

Due to huge difference between the time scale of the mantle convection and the outer core convection, they are modelled separately. In this week’s News and Views, Masaki Yoshida from the Volcanoes and Earth’s Interior Research Center, Japan Agency for Marine-Earth Science and Technology (JAMSTEC), Japan, put forward the recent development on the modeling of the whole solid-Earth. The E ...[Read More]

The short story of my PhD

The short story of my PhD

PhD students’ struggles are alike; each succeed in their own way[1] It was a Friday morning, and nearly 3 years had passed since I arrived at Sydney. This meant, I only had one month left to submit my thesis! No sooner had I entered my office than a feeling of anxiety had found me. I had no time to dig deep into my own thoughts to discover what was happening, although it was obvious. Instead, I re ...[Read More]

Modelling the deformation in the Indian plate and the India-Eurasia collision zone

Modelling the deformation in the Indian plate and the India-Eurasia collision zone

A complete fluid dynamical approach of modeling the Earth’s deformation can not provide a complete picture due to presence of rigid lithospheric plates. In this week’s news and views, Srishti Singh, scientist at National Geophysical Research Institute, India, explains how coupled models of lithosphere dynamics and mantle convection are developed.  The ongoing collision of the Indian plate wi ...[Read More]

Rayleigh-Taylor instability in geodynamics

Rayleigh-Taylor instability in geodynamics

Flow against gravity is a common feature in the geodynamic phenomenon. In this week’s Geodynamics 101, Dip Ghosh from Jadavpur University Geodynamics Lab will explain the fundamentals of Rayleigh-Taylor instability: A key to understanding the anti-gravity flow. It has long been realized that most of the geodynamic processes can be described in terms of slow viscous flow. Thus, like many othe ...[Read More]
