Hydrotalks: IAHS working group leaders and coordinators on HELPING scientific decade, working groups activities, and writing community papers

In episode 8 of the Hydrotalks podcast, we hosted four coordinators of working groups of the HELPING hydrological decade. We warmly welcomed Dr. Giulio Castelli (University of Florence) and Dr. Natalie Ceperley (University of Bern), group co-leaders of Co-Creating Water Knowledge working group; Dr. Soham Adla (ING Bank, Netherlands), a coordinator of Science communication, outreach, and promoting Digital Water Globe working group; and Dr. Ben Howard (Imperial College London), a coordinator of both working groups. We cover various topics such …


Tuna and Tufo: The geology and history of the Aegadian Islands near Sicily

The Aegadian or Egadi islands (not to be confused with the Aegean islands situated between present day Greece and Türkiye) is a small archipelago of islands around 20 km off the Western coast of Sicily. These islands are most known for their historic industries, namely for a type of rock quarried from the largest island (Favignana) and the large tuna fishery around the island. In recent times this area has been made a marine protected area and the quarrying has …


Under pressure: measuring stress within the crust

At the geodynamic scale, tectonic forces guide the distribution of stress. Stress in the Earth is not constant, but varies through space. Variations in gravitational energy caused by changes in mass distribution within the Earth, forces acting at plate boundaries, and basal mantle drag all cause stress to vary and act in different directions. Overall, stress plays a key role in tectonics. It allows plates to deform, faults to slip, and earthquakes to occur. It can trigger or delay future …
