“What if …?” – Creativity in flood risk management using counterfactual scenarios

“What if …?” – Creativity in flood risk management using counterfactual scenarios

Floods are among the most devastating natural hazards, claiming lives and damaging infrastructure.  The question of how we can be prepared for these extreme events quickly reaches an almost philosophical level: First of all, what is an extreme event? Second, how can we know what the future will bring?  For the last century hydrologists have relied on statistical concepts, which are based on observ ...[Read More]

GeoRoundup: the highlights of EGU Journals published during October!

GeoRoundup: the highlights of EGU Journals published during October!

Each month we feature specific Divisions of EGU and during the monthly GeoRoundup we put the journals that publish science from those Divisions at the top of the Highlights section. During this month, we are featuring Energy, Resources and the Environment (ERE) and Hydrological Sciences (HS). They are represented by the journals Geoscientific Model Development (GMD), Solid Earth (SE), Earth System ...[Read More]

Expanding the picture: Franck Ghomsi

A graphical illustration in watercolour optic with human silhouettes in different colours, and several smaller elements such as an ocean and a satellite.

What does a geodesist look like? And what happens if you don’t “look the part”? Today, Franck Ghomsi, a Black African scientist, takes us along on his journey between South Africa, Canada and Cameroon. Franck does not only research the impact of climate change on coasts with geodetic techniques, but at the same time became an expert in self-motivation, battling racism and fightin ...[Read More]

Dislocation Creep and the Development of Deformation Fabrics

Dislocation Creep and the Development of Deformation Fabrics

Assume you are under stress. What do you do? Take a walk in the park, order your favorite takeout, have a breakdown, or internally slip along preferred slip systems and develop a fabric? The response will mostly depend on what kind of material you are, how much stress you are under, and what environmental conditions you are subjected to. For instance, someone might listen to classical music after ...[Read More]

GeoTalk: meet Thanushika Gunatilake, researcher of earthquake impacts on geothermal energy

Hello Thanushika – welcome to GeoTalk! Before we delve deeper, could you introduce yourself to our readers? Thank you for having me! I’m Thanushika Gunatilake, an Assistant Professor at Vrije Universiteit Amsterdam. My research connects natural and human-induced processes in the Earth’s crust; from earthquake nucleation in the central Apennines, subduction dynamics, and volcanic activity, to geoth ...[Read More]

From Classroom to Community: Bridging Disaster Risk Reduction Education with the Real World Through Service-Learning

From Classroom to Community: Bridging Disaster Risk Reduction Education with the Real World Through Service-Learning

This week, we turn our attention to education and collaboration in Disaster Risk Reduction (DRR). Dr. Solmaz Mohadjer has been leading an innovative Service-Learning course that brings students together with non-profit organisations working at the forefront of risk reduction. The course not only introduces students to the complexities of disasters and resilience but also creates space for dialogue ...[Read More]

The Guinness Book of Sedimentology: your guide to the world’s largest EVER sedimentary landforms

The Guinness Book of Sedimentology: your guide to the world’s largest EVER sedimentary landforms

There is something about really BIG things that always grabs people’s attention – look at dinosaurs for example. The geological record is littered with the extreme and today we will explore the biggest, the tallest, the deepest and steepest sedimentary structures and landforms ever to grace our planet. Depositional environments ranging from fluvio-lacustrine and aeolian, coastal environments ...[Read More]

The spectral shadow of Samalas: When climate models conjure the Earth’s forgotten fury

The spectral shadow of Samalas: When climate models conjure the Earth’s forgotten fury

This Halloween, we turn our gaze from fictional haunts to the chilling, rigorous world of paleoclimatology. The paper by Hartmann et al. (2025), published on Climate of the Past, focuses on the implementation of external forcings in a regional climate model around the 1257 CE Samalas volcanic eruption. This paper can be quite the unsettling investigation, since it treats the Earth itself as a time ...[Read More]
