As a young scientist undertaking research into natural hazards and disaster reduction, I found the decision yesterday to find a number of scientists guilty of manslaughter very worrying. The case against the scientists is centred on the L’Aquila earthquake of 2009 and argues that they were guilty of providing “inexact, incomplete and contradictory” information. There is helpful a ...[Read More]

Top Travel Tips (6) – Daniel Sharpe
Over the summer we published a very popular series of posts outlining some Top Travel Tips to help those undertaking mapping projects, fieldwork or research visits overseas. We’ve had helpful posts from those who have spent time in various parts of Africa, Bangladesh, and Chile. Good preparation is essential to get the most out of overseas work. It helps our work be more effective, more effi ...[Read More]

Geology Photo of the Week #6 – Sept 30 – Oct 5
This is my first official post, besides the welcome post, at GeoSphere – EGU edition. It seems fitting to begin with a post that is part of a continuing series from my old home and is bridging the way to my new one. The photo of the week, while still only six weeks old, is and will stay a regular fixture on my blog. The photo for this week is of some fantastic glacial striations in glaciall ...[Read More]

Perspectives from EGU GA 2011 (6)
This year on the EGU General Assembly blog there will be guest posts from participants about their research and their impressions of sessions. These are personal points of view not EGU corporate views. If you would like to contribute a research or session viewpoint, please email us. This perspective from the European Geosciences Union General Asembly 2011 is from Thomas Smith about how to maximise ...[Read More]

More Than a Rain Gauge: When Salt Starts Steering the Sea
Posted in: Ocean Sciences | Reviews & Perspectives | Ocean Science Jubilee Special Issue We usually think of ocean salinity as the ocean’s rain gauge. Rain, rivers, and melting ice freshen the surface; evaporation leaves it saltier. Seen from space, these changing patterns reveal how Earth’s water cycle is evolving, with wet regions generally becoming fresher and dry regions saltier as the cli ...[Read More]

Reflecting on fifty years of Mars through Viking 1’s lens
On July 20, 1976, a machine of steel and titanium dropped through a thin atmosphere and touched the dirt of Chryse Planitia. Scientists at NASA held their breath, since five years earlier, the Soviet Union’s Mars 3 probe had died less than two minutes after touchdown. To mitigate this nightmare, engineers programmed Viking 1 to scan its own footpad first. If the lander sank into oblivion, hu ...[Read More]

Behind the Poster: An Interview with EGU 2025 Outstanding Student Paper Presentation (OSPP) Award Winner Carlos Castillo-Rivera
Congratulations on receiving the OSPP Award 2025! What was your reaction when you found out you had been selected for the award? I was very surprised when I received the email, and I read it several times to make sure it was real. After that, I felt extremely proud of my work because I could see the evaluation scores, comments, and recommendations from the judges. Their feedback confirmed that my ...[Read More]

The pulsed rise of the Nahuelbuta Range: How glaciers indirectly built a mountain in Patagonia
Forearc ranges are a striking example of how tectonic processes shape our planet. The Nahuelbuta Range in southern Chile is one of such settings. This week, Ambrosio Vega-Ruiz from the GFZ Helmholtz Centre for Geosciences, Germany, is telling us the story of this remarkable range, exploring how climate feedback can influence tectonic uplift across coastal forearcs. Tectonic uplift before tectonic ...[Read More]

Chasing glacial lakes in the shadow of Everest
Turquoise lakes. Towering Himalayan peaks. A maze of rock, ice and meltwater. At first glance, this hardly looks like a glacier at all (Figure 1)… Yet as glaciers thin and retreat across the Himalayas, networks of meltwater ponds and glacial lakes are forming both on glacier surfaces and at their margins: one of the most visible signs of a changing high-mountain landscape. I spent four weeks in Ne ...[Read More]

Could the Chilean Altiplano host natural hydrogen for the energy transition?
The contribution from Sergio León-Ríos, Associate Researcher at the Advanced Mining Technology Center (AMTC) at the University of Chile, where he does seismology research. Post edited by Adam Ciesielski prior to publication. Introduction Hydrogen sits at the heart of today’s energy transition. From policy documents to industry roadmaps, it is widely promoted as a clean alternative to fossil fuels. ...[Read More]
