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

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]

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

June 15, 2026

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]

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]
