Geomythology. Craitbul journey through the Newer Volcanics in SE Australia

Geomythology. Craitbul journey through the Newer Volcanics in SE Australia

The Aboriginals Australians had and hopefully will continue to have an important oral tradition, especially related to impacts, tsunamis, earthquakes and volcanoes. This time, I would like to set our new narrative in southeast Australia, where the Booandik people tell a story suggesting how their ancestors witnessed and interpreted volcanic activity in the Mount Gambier area. The story, reported b ...[Read More]

How to Create Your Own Water-Themed Audiotour

Imagine walking through the Swiss capital, Bern, a city full of water. While you walk, a voice from your headphones guides you along the way and tells you interesting facts about the river and other water sites. You discover the Matteschwelle dam, pass by several fountains, visit a historic weather station, and have a closer look at the clear blue water of the Aare River and its old bridges. This ...[Read More]

Living with a restless giant: The challenge of multi-risk management and communication at Campi Flegrei Volcano

Living with a restless giant: The challenge of multi-risk management and communication at Campi Flegrei Volcano

Nestled within one of Europe’s most densely populated regions, the Campi Flegrei caldera is a volcanic system whose secular unrest shapes the daily life of its inhabitants. Here, during the last decade and still ongoing crisis, ground uplift, frequent earthquakes, and persistent gas emissions interact to create a complex, evolving multi-risk environment. These natural hazards rarely follow simple ...[Read More]

Türkiye’s Climate at a Crossroads

Climate change is often described as a challenge of the future. Yet through our latest work, we’ve realized the future is already unfolding across Türkiye’s landscapes and climates. The signs are visible in the shifting seasons, intensifying heatwaves, and changes in rainfall… As one of the authors of the study “High-Resolution Projections of Bioclimatic Variables in Türkiye: Emerging Patter ...[Read More]

Harnessing Machine Learning to Advance Tropospheric Ozone Science

Machine learning (ML) and Artificial Intelligence (AI) offer powerful tools to address long-standing scientific challenges. At the molecular scale, we’ve seen projects like AlphaFold discover unknown protein structures and how they might interact with other molecules.  At the planetary scale, ML-driven models like GraphCast (Google), AIFS (ECMWF) and ACE (Allen Institute for AI) are revolutionizin ...[Read More]

Growing geological Christmas trees: salt ‘Christmas-tree’ structures explained

and December 3, 2025
Regional profile through salt structures in the eastern part of the Dutch graben, southern North Sea

As geoscientists, we tend to see geology everywhere. Around Christmas, many people stare at decorated fir trees and twinkling lights; salt tectonicists stare at seismic lines and outcrops and see… trees as well. Tall stems, branching limbs, stacked “tiers” of material; a whole forest of geological Christmas trees hiding in the subsurface. In salt provinces around the world, from the Flinders Range ...[Read More]

Co-creating water knowledge (Part 1): The history and future of an interdisciplinary working group

HELPING and the co-creation of a working group In 2023, the International Association of Hydrological Sciences (IAHS), inaugurated a new Scientific Decade, called HELPING – IAHS Science for Solutions decade, with Hydrology Engaging Local People IN one Global world. This third decade was established through  a bottom-up process, by investigating the interests and the urgency of  local hydrolo ...[Read More]
