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 on neighbouring faults. Second, for failu ...[Read More]

The Sassy Scientist – The Great Wall Of … Silence

Luiza is an active collaborator and wants to share every piece of her progress with her colleagues. However, there are some in her email chain particularly ‘busy’. At the end of her tether, she heaves a sigh: What to do if someone DOESN’T EMAIL BACK? Dear Luiza, Não se atreva tirar o cavalinho da chuva. Never give up. They’ll probably end up emailing you back. Someday. Unless  ...[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 in the environment – when I heard about oceanography it appealed to me straight ...[Read More]

Icy fieldwork: real or April Fool’s?

Those of us fortunate to participate in cryo-fieldwork are well aware of the unique, hilarious, and sometimes bizarre scenarios that we often find ourselves in. For this year’s April Fool’s Day, the EGU Cryosphere Blog team shares crazy anecdotes, with a catch: one of these stories is fake! Are you able to tell fact from fiction? Fill in the (twitter) poll, and time will tell if you are right…!! W ...[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 within the Indian plate since the mid-Cre ...[Read More]

A lot (but never too much) of hydrology at EGU22

The EGU General Assembly 2022 will take place on 23–27 May 2022, with more than 12,000 presentations that will be delivered and viewed both virtually or on-site in Vienna (Austria Center Vienna). About 1,900 presentations are included in the 99 scientific sessions that are led by the Hydrological Sciences (HS) Division. The 2022 conference programme is now online, but how do we navigate through th ...[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 water bodies had not existed, would w ...[Read More]

The Sassy Scientist – The Coffee Nirvana

Air travel is a thing of the past, or at least it has been in the past couple years. Nowadays conferences are attended from the comfort of our closet home-office. Although there are undeniable advantages in not being in the USA (please keep me out of there!), Sadia wonders: How to stay awake until 3am to present your poster at a virtual US conference? Dear Sadia, You are talking about a possible c ...[Read More]

There’s more to Geoscience than just oil and gas

There’s more to Geoscience than just oil and gas

When most people hear Geology, they might think ‘rocks’, ‘diamonds’ or ‘oil and gas’, and these perceptions of the Geosciences vary from country to country. This week, we have PhD student Ayuni Ina Mohamaad from the University of Florida to tell us more about the Malaysian view of geoscientists. Fresh out of high school in 2009, I was still unclear with how I would like to move forward in life, ca ...[Read More]
