Kdyby Lucy žila v Patagonii, tak by mohla sledovat vznik obrovských sesuvů.

The aftermath of the 1 March 2026 rockfall Fjæra in Etne in Norway. Image released by Frode Mæland
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.

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:

European ground motion service - skvělá služba, která zpracovává data z družic Sentinel-1, ukazuje, že se to tam hýbalo už posledních 6 let (oranžové a červené body značí pokles povrchu).

Takhle to tam vypadalo předtím. Podle dostupných informací má odlučná hrana sesuvu cca 4 km, to by znamenalo celý Z a V okraj města. Cca 1500 lidí muselo být evakuováno.
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.

Rock avalanche below Mt King George triggered by the 6 December 2025 Hubbard Glacier Earthquake. The runout distance is 1.4 km.

Aerial photograph showing the aftermath of the 24 June 2025 landslide at Houzihé Grand Bridge in Guizhou, China. Image from CNR. The image shows a large landslide scar with both carriage was destroyed. A truck can seen hanging over the edge of one of the carriageways.
On 24 June 2025, a significant landslide destroyed the Houzihé Grand Bridge on the Xiarong Expressway in Guizhou, China. A truck driver had an extremely lucky escape when his vehicle was left dangling into the void.

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.

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

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

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.
Tímto ale příběh nekončí. Materiál zablokoval řeku Lonza a začalo vznikat jezero, které v případě protrhnutí hráze může ohrozit obce níže po toku.
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! 😭

#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!

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