🔥🔥🔥 Old orogens – young topography 🔥🔥🔥 How do low mountain ranges evolve far away from active plate boundaries, and how do their topography and erosion patterns differ from collisional orogens such as the Alps? @unisalzburg.bsky.social @uni-freiburg.de www.sciencedirect.com/science/arti...

🌶️ Paper alert 🌶️ The recent publication of our PhD student Nicolas Villamizar-Escalante shows links between slab dynamics and the pattern of exhumation in the Calabrian Arc. Great job Nicolas! @unisalzburg.bsky.social @strucgeology.bsky.social www.sciencedirect.com/science/arti...

Beautiful Asturias Beach pebbles at the Atlantic coast of northern Spain - artwork by nature!

What a fantastic day in my backyard with Benjamin Campforts and highly motivated students from the University of Amsterdam. Triassic reefs, Pleistocene glaciations, retreating waterfalls, rockfalls, and costs for protective measure in a nutshell. @bcampforts.bsky.social @unisalzburg.bsky.social

What might the northern Calcareous Alps have looked like in the LGM? - and what are the links between glaciations and landslides? Here is an ice flow simulation for the Hochschwab massif (hosting the Wildalpen landslide) with the new code from: @hergarten.bsky.social # @unisalzburg.bsky.social

Are you interested in the evolution of high mountain peaks? Visit me at my talk tomorrow at the EGU in room G2, Session TS 4.2 (17:10 - 17:20). Hope to CU there !

:-) :-) :-) 10 fully-funded PhD positions :-) ::-) :-) Please forward to anyone who might be interested. We offer 10 PhD positions at the interface of geology, ecology and geography. In particular, I would like to promote subproject 6 (see figure). www.plus.ac.at/doctorate-sc...

Our doctoral program is now also in the public eye :⁠-⁠) salzburg.orf.at/stories/3286...

My book is still out there! Please use, adapt, and help maintain if you find it helpful for teaching!

This animation from the USGS shows the predicted shaking intensity from the M7 earthquake that occurred offshore of Cape Mendocino on December 5, 2024. 🧪⚒️ (Sound on)

Liran Goren just presented her recent work with Eitan Shelef on the links between channel concavity and drainage planform network. This is really elegant and captures the non-recoverable reorganization from wet➡️arid➡️wet climate cycles. esurf.copernicus.org/articles/12/...

In today's tectonic geomorphology course we discussed Davis' Cycle of Erosion (and differences to the models of Penck & Hack) and computed the hypsometric curves of catchments in the Sierra Nevada (Spain) following the recipe of Strahler, 1953. New ingredients: DEMs, GIS & Matlab! Old but gold!

How does relief evolve in intracontinental mountains, how quickly do they erode and what role does lithology play? Old orogen – young topography: lithological contrasts controlling erosion and relief formation in the Bohemian Massif egusphere.copernicus.org/preprints/20... @egu-esurf.bsky.social

Last week's rollercoaster ride started with endless classes despite a cold, but took a very positive turn with the announcement that our €2.5 million doctoral program had been funded. Back to full health, Salzburg never disappoints on weekends with its great outdoor options!

Just grateful...

What would the world be without mushrooms? Most of the year they are almost invisibly hidden in the ground, but in the autumn forest they reveal their many shapes and colors. Many species are dependent on the substrate, resulting in an exciting relationship between fungi, soil types and bedrock.

Why is geology important to understand the climate of the past and the future and to mitigate the consequences of climate change? I had great hours discussing these and other questions with students from St. Rupert Gymnasium (Bischofshofen). Thanks for the photos Paul @pamoe.bsky.social

On invitation of the Rotary Club Bischofshofen, I was given the opportunity to speak to a great audience about global links in the climate system, about different time scales of climate change and their impacts on the Alps. Thanks to @pamoe.bsky.social for this enjoyable evening and the photographs.

One of my favorite views of the Dachstein. Rock climbing in my backyard 🤩.

The Eastern Alps are not the Himalayas, but anyone who claims they are a small mountain range only knows them from maps. A few big turns on the white gold in the middle of nowhere - simply the best! 🤩🤩🤩

Today's lecture: Equations are the best friends of geologists. In combination with a few cookies, the diffusion (heat) equation was quite easy to digest for our students 😁. ⚒️

I managed to escape the office and went skiing in my backward 🤩. Being alone in the mountains is always great for generating new ideas and thinking about future projects.

Benchmarking codes is essential to find weaknesses and correct bugs. Finding a setup that works for all codes is difficult because even grids are structured differently (in the picture you can see the quadtree grid from Gerris and our extension for rapid mass movements).

⚒️ 😁 #geology

I defended my PhD almost 20 years ago. Today, my former PhD supervisor (Kurt Stüwe) visited me and we moved the project meeting to my beloved backyard :-). 20 years later we still enjoy working on projects together as friends - that's what good mentoring is all about.

Strong pleas at the Falling Walls Science Summit in Berlin by Johan Rockström @pik-potsdam.bsky.social and Lars Peter Riishøjgaard WMO: it's time to push the panic button and act to bring CO2 levels down. All regulations are in place, but have not impacted CO2 increase. Can COP28 move to mitigation?

Doctoral school kicked off this morning with a talk by Matthias Bernet (Grenoble) on mountain building and biodiversity. Followed by a talks on climate and tectonics coupling and biodiversity changes

Hello new followers! Please repost so we can reach a much wider audience!

I am still positively surprised at how well the debris flow code works, which I wrote 15 years ago as part of my work in a geological office. In today's course we use model results to determine the potential impact of debris flows on infrastructure. #Teaching at the University of Salzburg ⚒️

In tomorrow's GIS course we will be working on alpine natural hazards (e.g. rockfall) and impact analysis. The exercise serves as preparation for the dimensioning of protective structures for infrastructure in alpine areas - a typical task for our graduates in their future everyday work. 🧪 ⚒️

⚒️ 😅

Fantastic outcrop of the Oberalm Fm. with marls and clay-rich beds (background sedimentation), and calcareous turbitites. The iconic peaks of the Barmsteine - landmark of my hometown - were formed due to the resistance of the thick, almost vertical turbitite beds to erosive surface processes.

It is often the unimpressive rocks that mark major changes in the evolution of life on Earth. Embedded between the Middle and Upper Triassic carbonate platforms, the fine-clastic Carnian sedimentary rocks, a few meters thick, bear witness to a global climate change: the Carnian pluvial event. ⚒️

Vacation and rainy weather - finally time to deal with the wonderful paleotopography data from Scotese and Wright (2018) (www.earthbyte.org) as part of an outreach project. An impressive way to explain the origin of the Upper Triassic and Jurassic rocks in the Taugl catchment (Eastern Alps) ⚒️.

I become aware of the deep time at the sight of tropical, Upper Triassic carbonate platforms, which today form almost 3000 m high mountains covered by melting 😭 glaciers. What are in comparison the 100 years, which we participate in the earth history - our impact is already huge ⚒️.

Golden October 🤩!

I am currently working on an outreach project for a local museum that is preparing a special exhibition for an alpine catchment. I can't stop looking at the digital elevation model of the catchment. LiDAR is just cool.

Rough and rugged, rainy, foggy - that's how the Alps are and I like it.

It takes a bit of effort to cycle to work in the dark. But often you are rewarded for it: sky in flames over the Salzach River.

Arriving on the other side I choose a clear sky for the first post on blue sky. The photo was taken in my backyards (Hohe Göll area, Northern Calcareous Alps) during an after-work climbing session. Let's see how this social network will evolve.
