From Rocks to Models: Reconciling Field Geology with Geodynamic Simulations

From Rocks to Models: Reconciling Field Geology with Geodynamic Simulations

When reading a scientific paper or a text explaining the physical workings of the Earth, one of the most striking aspects is the methodological approach—sometimes involving numerical models, other times fieldwork and/or rock geochemistry. This diversity of approaches can initially cause some discomfort, a feeling that things are like square pegs in round holes. How …[Read More]

TS Must-Read – Fossen and Cavalcante (2017): Shear zones – A review

TS Must-Read – Fossen and Cavalcante (2017): Shear zones – A review

Haakon Fossen and Geane Carolina G. Cavalcante published their seminal review on the topic of shear zones in 2017 in the journal Earth-Science Reviews. The work summarizes the scientific findings on the development and quantification of ductile shear zones sincefrom the the 1960s up to recently. It describes the fundamental aspects of the initiation and …[Read More]

How do rocks fail and flow: A beginners guide to rock rheology

How do rocks fail and flow: A beginners guide to rock rheology

The field of rock rheology may seem a bit ‘odd’ at first glance to those geoscientists who are vaguely familiarized with the topic of geodynamics. Often, rocks are considered massive and competent geomaterials that display a sudden (and sometimes violent) brittle failure (earthquake alert!). However, when considering the high temperatures and large timescale characteristics of …[Read More]

No Resilience Without Trust – An interview with Janise Rodgers and Mary Antonette Beroya-Eitner from GeoHazards International

No Resilience Without Trust – An interview with Janise Rodgers and Mary Antonette Beroya-Eitner from GeoHazards International

This summer, we participated in a Service-Learning course titled “Breaking the Cycle of Disaster, Response, Recover, and Repeat”. The course was developed by Solmaz Mohadjer and offered as part of the Transdisciplinary Course Program at the University of Tübingen, Germany. We were brought together from different disciplines to explore key factors that contribute to effective …[Read More]

Geodesy Cartoon Competition – Turn Science into Smiles

Geodesy Cartoon Competition – Turn Science into Smiles

Geodesy is the science of measuring the Earth’s shape, gravity field, and rotation. What if we could make it exciting, fun, and easy for everyone to understand? That’s exactly why the International Association of Geodesy (IAG) and its Global Geodetic Observing System (GGOS) launched the Geodesy Cartoons initiative: to bring geodesy closer to the public …[Read More]

Microbial Adventures in the Mont Blanc Massif

Microbial Adventures in the Mont Blanc Massif

As we passed the town of Saint-Gervais-Les-Bains on the French highway, en route to a sampling campaign, Mont Blanc’s glaciated terrain suddenly emerged above the spring foliage. Breaking the silent awe, Patrick remarked that indeed, “Mont Blanc is still there.” The humor won’t be lost on anyone familiar with the massif. Its unquestionable, human-minimizing presence …[Read More]
