TS Must-Read – Cowie (1998) A healing-reloading feedback control on the growth rate of seismogenic faults

This study provides a simple numerical model of fault rupture that describes the development of fault systems from the initial nucleation of numerous small faults to the localisation of deformation into few major faults. The model presented is based on two main considerations: first, earthquakes cause stress changes that can either advance or delay failure …[Read More]

OceanTalk with Karen J. Heywood

Karen smiles on the left by the ship railing, with the open ocean behind

Karen J. Heywood FRS is a Professor of Physical Oceanography at the University of East Anglia, UK. Karen was president of EGU’s Ocean Sciences division from 2016-2021. Can you tell us about your background and career path? I did a physics degree back in the early 1980’s, and then wanted to apply that to something …[Read More]

Journey of the Indian plate

Journey of the Indian plate

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 …[Read More]

The fragile connection of the Ocean and the Cryosphere – a story from the past

The fragile connection of the Ocean and the Cryosphere – a story from the past

Compared to the formation and evolution of the Earth’s surface, the ancient oceans receive little attention in geological history. However, understanding the rise and fall of the oceans of the past—or “ghost oceans”—can reveal crucial information about the evolution of our planet, the cryosphere included. Can oceans play a historical role in climate change? If …[Read More]
