Plate interface lubrication is essential for stabilization and continuation of subduction process for million of years. The magnitude of plate interface lubrication determines transfer of stress between two converging plates, topography of mountain belts, transportation of volatiles to the mantle, and return flow of high to ultra-high pressure rocks to the earth’s surface. In this week’s blog, I ...[Read More]

Plume craton interaction is a fascinating geological phenomenon. The Indian plate, which has experienced several plume eruptions underneath it, is one of the best locations to study the effect of plume craton interaction. In this week’s news and view, I will provide an overview of the controversy and hypotheses related to the plume craton interaction within the Indian plate since the mid-Cre ...[Read More]

Repurposing a research tectonic modeling code as a community service: The case of DES3D

Eunseo Choi and edited by Arushi Saxena October 6, 2021

Three-dimensional model for core complex formation created with DES3D by Eunseo and his research group. Accelerated on NVidia V100 graphics card.

This week, Dr. Eunseo Choi, a professor at the Center for Earthquake Research and Information, the University of Memphis, talks about tectonic modelling using DES3D. *Spoiler alert* read till the end for an exciting opportunity to work on it The advent of the open-source movement and the free public software repositories such as GitHub have drastically improved the way research codes are maintaine ...[Read More]

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

Masaki Yoshida and edited by Jyotirmoy Paul May 5, 2021

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]
