Modeling the full spectrum of observed seismicity: Insights from friction laws, fault instability, and fault-zone mechanics

Modeling the full spectrum of observed seismicity: Insights from friction laws, fault instability, and fault-zone mechanics

Introduction Despite advances in our understanding of rock mechanics, the frictional behavior of rocks, and the physics of instability in geological materials, the coexistence of slow and fast earthquakes, as well as various types of fault-zone seismic radiation such as tremor, remains enigmatic. Can fault mechanics and friction laws reproduce the full spectrum of observed …[Read More]

Book Review: The Swarm by Frank Schätzing

Book Review: The Swarm by Frank Schätzing

So far, our reading adventures have kept us close to reality with Blue Machine by Helen Czerski and Below the Edge of Darkness by Edith Widder. Now, we are turning to a work of fiction. The author did plenty of research and spoke with scientists, who even appear as characters in the book, resulting in the science-fiction eco-thriller The …[Read More]

Interdisciplinary futures in geoscience: Cross-divisional insights from the Division Presidents – Atmospheric Sciences (AS)

Interdisciplinary futures in geoscience: Cross-divisional insights from the Division Presidents – Atmospheric Sciences (AS)

This interview is part of an ongoing series exploring the evolving role of interdisciplinarity across the geosciences. As environmental challenges grow more complex, addressing them requires not only disciplinary expertise but also meaningful collaboration and innovation across fields, methodologies, and communities. In each conversation, I ask Division Presidents to reflect on how cross-divisional work is …[Read More]

When multiple hazards interact and the data doesn’t: The multi-hazard modelling problem nobody wants to talk about

There is a quiet contradiction at the heart of natural hazard science. The regions most exposed to multi-hazard events are precisely the regions where we know the least. The Global South (comprising lower- and middle-income countries in Africa, Asia, Latin America and the Caribbean) is disproportionately affected by climate-related natural hazards, yet it is largely …[Read More]

Pride month in the era of DEI rollbacks: Reflections on resilience, and why pride was a riot after all

Pride month in the era of DEI rollbacks: Reflections on resilience, and why pride was a riot after all

Pride month arrives this year against a backdrop of institutional irony. In the United States, federal research funding has been thoroughly weaponised and forced a massive scientific brain drain across the Atlantic. In Europe, a multi-million-euro effort to capture that exiled talent is underway, even as Europe’s own domestic politics fracture along the exact same …[Read More]

Geodesy Cartoons – A Creative Tool for Outreach and Education

The Geodetic Tailor (cropped). Cartoon by Eda Uzunoglu, distributed by geodesy.science/cartoon. CC BY.

Geodesy is fundamental to understanding our dynamic planet. From monitoring sea-level rise and glacier melt to maintaining precise terrestrial reference frames for GNSS and Earth observation, geodesy provides the scientific backbone for many disciplines represented within the EGU and beyond. Despite its importance, geodesy often remains invisible outside the scientific community. Even within geosciences, many people …[Read More]
