Danke das hab ich schon gesehen aber wenn ma das Full screen zeigt ist es sehr grob gerastert….

Marcus, gibt es einen link zum download dieser grafiken in guter aufloesung (high res oder PDF) fuer vortrage etc???

Mountains are among the planet’s most beautiful places. They’re also becoming the deadliest | CNN These majestic landscapes have always been dangerous, but as the world warms, mountains are becoming much more unpredictable — and the world is unprepared.

This article about mountain and cryospheric hazards, featuring quotes from @davepetley.bsky.social @matthias-huss.bsky.social @janbeutel.bsky.social and others was published a few months ago, but is still very relevant 🧪⚒️ www.cnn.com/2025/06/07/c...

Check out the video abstract

Water causes rock to shift on the Matterhorn SLF research on the Matterhorn shows how meltwater in permafrost can lead to rock slope instability – a consequence of climate change.

SLF did a nice explainer also for non scientists:

Of course this is many magnitudes smaller than #Blatten and the Klein Nesthorn ridge collapse. But hey, the GNSS monitoring technology developed here truly delivered and consequently lives were saved.

Super stoked our Matterhorn-Tower-Collapse paper is finally out @egu-esurf.bsky.social. Read all about what it takes to be able to now compute in simulation how thawing and fluid water availability influences real rock slope instabilities at high altitude:

#IMC25 - The avalanche disaster in Blatten

Check out the great lineup of speakers for our workshop tomorrow "The avalanche disaster in Blatten"
where first insights and science results will be discussed.

Seeing #Blatten and the #Nesthorn collapse for real does leave a lasting impression. Yellow CAT excavators waiting look like ants.

Same ballpark as the media conf yesterday (9mio) and great we can have such analysis do quickly

Samidha, this is from the seismic networks accessible via FDSN. mass movements are tracked and cataloged by SED since a couple of years:

seismo.ethz.ch/en/earthquak...

That's because i already had a sip at the 🍺before the 📸

The evac was based on pre-failure analysis of an imminent, very large rockfall. An in-situ GNSS sensor installed on friday 16th on the ridge as well as a first large rockfall caused the evac decision monday. Fun fact, the GNSS fell with one of the first rockfall events monday afternoon.

And no: "...Emergency managers had been observing increased glacier melt at Birch Glacier, ordering hundreds of villagers to evacuate after debris from the mountain behind the glacier crumbled days before the catastrophic collapse."

Its an awkward article mixing different quotes, specifics and non-specifics as well as non truths. only one example: "...can melt permafrost..." - well if solid ground melted that would be lava i'm afraid. also

After a full day of non stop interviews on rockfall, glaciers, permafrost and Valais natural hazard management it’s nice to end the day in a peaceful mountain setting. Why is it that despite how many times you explain that rocks fall because of this climate thingy they still put it in the headlines?

All these events register nicely on the map. This is the biggest rockfall event and the seismic signal geolocates just at the base of the ridge. Also the geological situation and the permafrost question is illustrated (darker violet/blue means permafrost is more likely than yellow).

Another magnitude 1.0 event was registered yesterday at 2025-05-29 12:34 in #Blatten. In the line of the 15 events registered over the past two weeks this one parks in at a moderate scale. And just another reminder that the mountain has not yet reached an equilibrium state yet.

somehow i like this pointy hill. only why?😀

Absolutely stunning ultra-high resolution @planet.com SkySat imagery of the Klein Nesthorn landslide, which buried the village of Blatten, Switzerland yesterday. @davepetley.bsky.social @eth-eaps.bsky.social @vaw-glaciology.bsky.social @kristencook.bsky.social @annepellegrino.bsky.social 🧪⚒️🛰️

Methods that were groundbreaking in basic research are now butter and bread go-to-methods - in real time: 15:24h event happens, 15:30h E sent email request to SED to quickly check magnitude because of deteriorating visibility, 15:39 we KNOW it's M=3.1

And there clearly is another thing "posterchild" about this. The remarkable capabilities and calmness in mitigation combined with innovative monitoring and assessment methods.

Swiss Seismological Survey published a nice overview plot of the earth shaking and wobbling as response to first a series of rockfalls/rockslides onto the Birchgletscher and then finally more and more mumbling and rumbling leading to the final break-off.

The Birchgletscher collapse shook the Matterhorn!

Not really a surprise but a fun fact that the collapse of the Birchgletscher is clearly visible at our high-altitude seismic station Solvay 4003 m a.s.l. up on the Hörnliridge (bottom left).

So what you are describing is the start of the failure process, then it takes some time until the sliding and tumbling creates enough energy for the big signal (the impacts downstream). This is the details from SED
