Kdyby Lucy žila v Patagonii, tak by mohla sledovat vznik obrovských sesuvů. alive.osu.cz/patagonie-3-... Krátce o našem posledním článku z Patagonie.

On 1 March 2026, a dramatic rockfall occurred on the E134 road at Fjæra in Norway. An occupied pickup truck was crushed, but no-one was killed. The event was captured in an excellent video. eos.org/thelandslide... Image by Frode Mæland, who owns (owned?) the car.

Průtok a sklon koryta vs. množství a velikost sedimentů. Základní koncept fluviální geomorfologie ukazující chování vodních toků. Trochu jsem blbnul Claude Code a vytvořil vizualizaci tohoto konceptu. Můžete vyzkoušet zde: michalbrezny.github.io/River-Balance/

Na Sicílii došlo k obrovskému sesuvu. Možná vás tato zpráva minula, protože jste sledovali jinou katastrofu, která se nachází v Černínském paláci. Každopádně záběry z města Niscemi jsou ohromující. Některé domy stojí nad odhadem 30 m vysokým útesem. www.youtube.com/watch?v=9tCD...

Back from the mountain rivers of Greece! We collected field data for simulating future floods in a catchment hit by Storm Daniel in 2023. Bonus: photos captured on 35mm film with my old Leica 📷🌊

🚨 New paper out in CATENA! After 6 years of fieldwork in Czech headwater streams, we show: ✅ In channelized streams, gravel moves farther. ✅ In near-natural streams, sediment transport is more predictable—better linked to flow magnitude & duration. Read more: www.sciencedirect.com/science/arti...

Návrat k událostem, které vedly k pohřbení vesnice Blatten. Aneb krátce o sesuvech a změně klimatu. ekolist.cz/cz/publicist...

First drone flight today at Blatten! 🌊🎥 Water has made its path through the deposit! A spillover is currently not expected Slight lowering of upstream lake, which is currently not high enough to spill over the debris cone Several new lakes created on the deposit Source SRF 1/

BEFORE / AFTER Birch glacier collapse 😮😱 There WAS a glacier here! 🧊 Not only the front, but the entire ice mass has slid down the valley! 🌊 Glad Alain Amherd took two pics with the same angle! 📷🙏

The fascinating thing about these images of the #Blatten event is the scale of the original rockslide that got us all excited a week ago. It is just visible towards the top of the slope. This is a posterchild for a complex, cascading hazard that evolves rapidly and unpredictably.

Švýcarská vesnice Blatten byla dnes z velké části pohřbena pod masou ledu, sutě a kmenů. Kolaps ledovce Birch završil několikadenní drama. To začalo murou, evakuací vesnice a sesuvem z Kleine Nesthorn. Sesuv způsobil zrychlení pohybu ledovce, které vyústilo v dnešní kolaps.

INCREDIBLE !! Here we are... 😱😱😱 After days of overloading and cracks propagating, Birch Glacier collapsed today at 3.24 pm over Blatten and the dammed Lonza river... Devastating! 😭 www.letemps.ch/suisse/valai...

Upstream and downstream view of the deposit! 🧊🌊 Massive... 😱😱😱 www.letemps.ch/suisse/valai...

Before and after image of the large glacier collapse that covered parts of the Swiss village #Blatten. The animation is stabilized/aligned from a version shared by Pomona/Alain Amherd Source: pomona.ch/en/story/590...

#Blatten Press conference Alban Brigger, -glacier front velocity is 2.5-3 m/day. ‘We do not expect an exponential acceleration, as we feared before.’ -the amount of debris deposited on the glacier is 3.5 Mm3 = 9 M t. Up to 80 m thick! 1/ 📷 Keystone

This is a completely new landslide trigger for me - the impact of a 100 m cargo ship. Utterly bizarre.

Ve Švýcarských Alpách nikterak malý (asi 5 miliónů m3 skály) aktivní sesuv ohrožuje vesnici, která musel být evakuována. Online reportáž a další snímky najdete zde: www.aargauerzeitung.ch/schweiz/droh... Případně sledujte @subfossilguy.bsky.social

Today (~12pm) the scar has reached the top of Klein #Nesthorn which resulted in a lowering of the crest and a ruiniform morphology!😳😱 📷 sensalpin.ch

Already + 100,000 m3 fallen from the Klein Nesthorn N face at ~3200 m asl, and something between 1 to 5 Millions m3 more are 'forecasted'... 😱 That's quite a thing! Blatten village evacuated 😭 The 'Crumblocene' is definitely a nice time to live! 🏔️🌊 www.20min.ch/fr/story/can...

I discovered today that Google Earth now has post-earthquake imagery from the 3/28/25 M7.8 earthquake in Myanmar. The area includes the site we trenched in 2018 before the earthquake to look for evidence of past earthquakes. The image shows the locations of our trenches with the 2025 ruptures. 1/3

A bit of a break during fieldwork—here are a few analog shots from our monitoring of gravel bars on the Elbe River near the CZ/DE border. Captured with a 70y old Leica IIIg + Elmar 50 mm 3.5 + Fomapan Ortho 400. Always nice to mix science with some classic photography!

Planning to attend the IAG Conference in New Zealand next year? Working with fluvial systems? If yes, consider submitting an abstract to our session: "Lessons Learned About Anthropogenic Drivers in River Evolution." www.confer.co.nz/icg2026/anth...

(1/2) Much has been said about the degradation of gravel bars due to river regulation — but far less is known about how they can develop in long-channelized reaches ▶️

Trump has done the same damage to our health, environment and security as to our markets, it's just that there isn't a stock ticker that measures the impact so clearly

Spent last week crisscrossing Czechia, collecting hydromorphological data from all sorts of streams and rivers. It was a great reminder of how wildly diverse our fluvial systems are — and, at times, how brutally over-regulated some channels still are… even out in the countryside 🤕

Po třinácti letech zase v kapele… asi mam dost času 😆

Oblast Thajska a Barmy dneska ráno postihlo silné zemětřesení o magnitudu 7,7. V oblasti budou značné materiální škody i oběti na životech. Tady je například video z Bangkoku ukazující kolaps rozestavěné výškové budovy.

Some photos of this year's field in Patagonia. Probably the last visit to this part of Patagonia in my life. And maybe Patagonia in general... A little nostalgia.

Kroky politické reprezentace USA otřásají tamní vědou. Poslední týdny probíhá nátlak na univerzity, aby se vzdaly autonomie a svobody bádání a snahu cenzurovat vědecké poznání, které se z ideologického hlediska nehodí. Ač jsme obvykle apolitičtí, sepsali jsme toto vyjádření 👇 1/3

Viedma Glacier 2017 | 2025 Viedma (3rd largest glacier in South America) has known the most incredible rate of frontal ablation recently! 🔥 What's even more striking is that this is happening above what has just become the deepest lake on the American continent (919 m deep)! 🥇🧊🌊 1/

In my city there is one cybertruck and one DIY parody of a cybertruck and the parody truck has become a local celebrity. Meanwhile, I always wish I had some rotten eggs to throw at the tesla whenever I see it.

Tihle už jedou ve full-Hitler módu...

Díky za karty @lukasfibrich.bsky.social ! Vypadají skvěle! A věřím, že se budou líbit i obdarovanému 🙂

Geoscientists of BlueSky, ⚒️ Just look at this damn thing🤔🧐 What the damn!?

OR made property-level wildfire risk maps in 2022. Homeowners were "unhappy" about being classified as 'high-risk'. Now officials are backtracking to map much broader areas of risk. These politicians care more about their own job than the actual science oregoncapitalchronicle.com/2025/02/10/s...

Co se vlastně děje na hasičské stanici při vyhlášení poplachu? Pro to, abychom stihli dvouminutový limit ve dne i v noci, si umíme mnoho činností zautomatizovat. Rozsah se pak odvíjí jak od stáří stanice - nové toho pochopitelně umí nejvíce - tak od požadavků samotných hasičů.

I was just told that I have to remove “climate” from the title of an ongoing grant if I want to keep it. And publications from that grant cannot include “climate” and other forbidden words. I can’t believe I’m writing this from the United States of America. #AcademicSky
