How climate change can possibly increase the intensity of tornadoes in Europe

Davide Faranda October 26, 2022

On October 23 2022, a tornado outbreak occurred in France, causing extensive damages. Tornadoes in France are a relatively rare phenomenon, even more so in the second half of October. This weather phenomenon is linked to intense thunderstorms, and it is difficult to predict because it is very localized. Will global warming make this weather more frequent or intense? A thundercloud that grows visib ...[Read More]

When race and natural hazards intersect: three geoscientists share their experiences

Gillian D'Souza October 26, 2022

Around the world, the month of October is observed as Black History Month and includes the International Day for Disaster Reduction. While both these observances are significant in their own right, it gave EGU the opportunity to hear from geoscientists of Black, Indigenous, and People of Colour (BIPOC) communities about the many ways that race and natural hazards are linked: does one affect the ot ...[Read More]

The sedaDNA scientific society, a collaborative network of international researchers working with sedimentary ancient DNA

Eric Capo October 26, 2022

A group of people working together on laptops around a table in a room.

Emergence of the field of molecular paleoecology Sequencing DNA of organisms that died a long time ago sounds like the synopsis of the movie Jurassic Park (1993). Let’s make it clear right now, dinosaur DNA has never been collected by humans. To date, the oldest DNA recovered is more than one million years old and comes from mammoths. In addition to the DNA recovered from fossils, aquatic and terr ...[Read More]

Unravelling the geological past of the Sierra del Nevado, in South Andes, Argentina

Georgina Rubiano Lorenzoni and edited by Kleoniki Lydia Theodoridou October 26, 2022

Have you ever wondered to learn more about the geological setting of the Nevado volcano in Central-West Argentina? In this week’s blog, we have Georgina Rubiano Lorenzoni, a Ph.D. Geologist student from the Universidad Nacional de La Pampa in Argentina, who will guide us through her thesis aims, which are the identification and investigation of the petrogenesis and geochronology of the mountain ra ...[Read More]

Imaggeo On Monday: Drought – a prerequisite for hazardous flash floods

Stefan Schmitt October 24, 2022

The drying out of the soil leads to the hazard of flash floods in the wadis of the Dead Sea Valley during sparse but strong rain events. During longer precipitation-free periods and extreme low relative humidity, driven by mesoscale wind, the soil crust ultimately tends to break into piece. Photo by Stefan Schmitt, description from imaggeo.egu.eu. Imaggeo is the EGU’s online open access geo ...[Read More]

Let’s begin the recovery before the disaster

Soheil Mohammadi October 24, 2022

Every natural event that causes damage to the built environment must be followed by recovery; however, this phase of disaster risk management has received less attention from academics than the others [1]. In all its aspects, disaster recovery has remained a contentious topic, with experts debating its definition, approaches, objectives, activities, and even when it should begin and finish [2–4]. ...[Read More]

International Continental Scientific Drilling Program Workshops – How they work and why they provide fascinating experiences and perspectives, especially for early career scientists

Marta Marchegiano October 24, 2022

Thanks to the novelty and potential of my research focus (a paleothermometer for lacustrine environments based on the application of the carbonate clumped isotope technique on small crustacea shells (ostracods)) that provides insights into atmospheric temperatures of the past, I was selected by the committees of three International Continental Scientific Drilling Program (ICDP) workshops. The aim ...[Read More]

GeoPolicy: Connect with artists to make your science accessible to policymakers and the public

Noel C. Baker October 21, 2022

Communicating with the public and policymakers enables scientists to share their passion with those outside of their field and create greater impact. Often when scientists consider engaging non-experts, they imagine public lectures or blog posts, but finding more creative ways to communicate scientific information can be both rewarding and incredibly effective. This month’s GeoPolicy Blog post is ...[Read More]

The Global Arctic, a personal perspective on interdisciplinary research

Ugo Nanni October 21, 2022

Around the summer solstice of 2022, a small group of twenty young researchers met in Svalbard, a small island lost between Norway and the North Pole. The Norwegian Scientific Academy for Polar Research wanted to bring us together around the theme of “The Global Arctic“. The scope of this summer school was to “produce a better understanding of the significance of the concept of Gl ...[Read More]

Fagradalsfjall 2021 versus 2022: similarity and differences

Elisabetta Billotta October 19, 2022

The Icelandic eruptions of 2021 and 2022 originated in the Reykjanes peninsula, characterized by the Krýsuvík-Trölladyngja system, one of the five volcanic systems present along the peninsula. This peninsula is a leaky transform fault, characterized by episodic rifts and associated volcanism. The last two years have brought about some of the most momentous volcanic eruptions in recent history. The ...[Read More]
