EGU24 – A Hydrologist’s Look Back

EGU24 – A Hydrologist’s Look Back

With almost 21,000 participants, the 2024 EGU General Assembly, held from 14-19 April, in Vienna and online, was the biggest one yet. For hydrologists, there were hundreds of sessions to enjoy, networking events to join, short courses to learn from, and colleagues to meet. Here’s a look back at the highlights! A look back at EGU24. Thanks to Tasty Edits for the fantastic video edit!  101+ Scientif ...[Read More]

TS Must-Read – Wang et al. (2012) Deformation cycles of subduction earthquakes in a viscoelastic Earth

Large subduction earthquakes cause perturbation of the subduction system, whose response depends on its rheological characteristics. The evolution of the subduction system from earthquake to earthquake is defined as subduction earthquake cycle (SEC), and is characterised by three main processes that operate over decades/centuries: postseismic afterslip, viscoelastic mantle relaxation, and fault re ...[Read More]

EGU General Assembly 2024 — A Brief Recap of our Activities

EGU General Assembly 2024 — A Brief Recap of our Activities

Thank you all for the great EGU General Assembly (GA) this year! In case you missed EGU24 or some of the events we organised, here is a little recap. So you can stop wondering how it went and get an idea of what to look out for next year. In the Geodesy Divison, we had our kick-off, unlike the standard, with the online division meeting on Wednesday before the EGU24. There, we introduced our new me ...[Read More]

Do-It-Yourself (DIY) in Geoscience Miniseries – Part 3: Getting it all together – Cables, Breadboards and Circuit Boards

Do-It-Yourself (DIY) in Geoscience Miniseries – Part 3: Getting it all together – Cables, Breadboards and Circuit Boards

You got all your components for your project, so now it’s all about getting it all together. Then it’s great to be able to quickly exchange components and change wiring. That’s where a so-called “breadboard” comes in handy. It’s an easy to use device where you can connect microelectronic components without the need to solder anything.   Breadboards are like pinboards for cables and microelect ...[Read More]

Linking the Earth’s Engine and Landscape Formation and Evolution

Linking the Earth’s Engine and Landscape Formation and Evolution

The Earth’s internal engine drives several geodynamic processes such as continental rifting and dynamic topography, shaping mesmerizing landscapes. Through numerical modeling, insights into formations like the Continental Rift of Southeastern Brazil deepen our appreciation of Earth’s dynamic nature and the forces sculpting its surface. The heat engine beneath our feet Not so long ago, ...[Read More]

Using rainy day temperatures to predict the future of 100-year downpours

Using rainy day temperatures to predict the future of 100-year downpours

It’s hard to overstate the importance of so-called “rainfall frequency analysis,” or the estimation of rare rainfall probabilities such as the 100-year storm. Billions of euros worth of infrastructure and planning decisions are made every year around the world based on such statistics.  Unfortunately, extreme short-duration rainfall—meaning very high rainfall rates over a few minutes to a few hour ...[Read More]

Modelling the heat mitigation effects of blue roofs and green roofs to assess climate change adaptation potentials in dense urban environments

Modelling the heat mitigation effects of blue roofs and green roofs to assess climate change adaptation potentials in dense urban environments

Urban areas often show higher temperatures than their surrounding rural areas, especially during heat events. This phenomenon is called the Urban Heat Island (UHI) effect. The magnitude of the UHI effect is expressed by the absolute temperature difference between the rural and the urban area and can reach more than 10 °C. During past decades, the magnitude of the UHI effect has intensified in many ...[Read More]

Exploring rheology of Earth’s materials: The marvels of high-temperature high-pressure deformation experiments

The Earth, with its towering mountains, shifting tectonic plates, and dynamic geological processes, has always been a subject of fascination and inquiry for scientists. Amidst the vast array of scientific disciplines, one relatively small yet impactful field, known as experimental rock deformation, plays a crucial role in unraveling the mysteries hidden beneath the Earth’s surface. Though th ...[Read More]

Disentangling the complexity of multi-(hazard-)risks: conversations with Marleen de Ruiter, the EGU NH Division 2024 Early Career Scientist Award Winner

Marleen de Ruiter is Assistant Professor at the Institute for Environmental Studies (IVM), Vrije Universiteit Amsterdam. Her research focuses on multi- and consecutive disasters, improving modeling capabilities and understanding of multi-hazard risk and assessing the potential adverse impacts of Disaster Risk Reduction measures across different hazards. She manages the Myriad-EU project, co-leads ...[Read More]

You thought it was over? Here’s more on the 2023 Antarctic sea-ice extent record low

A figure showing several lines for several years of sea ice extent. They look like a wave with the minimum around february each year and the maximum around october.

  In November last year (see this post), we promised to provide you an update of what happened with Antarctic sea ice during the year 2023 – a year of an exceptionally low extent. In this post, we try our best to discuss the conditions that lead to (part of) the recent loss in Antarctic sea ice, including atmospheric and ocean processes. How sea ice usually works… One of the ways scientists h ...[Read More]
