X post by @nobushiromasaki. JP text: カムチャッカ半島付近の大地震（M8.0）による津波、日本各地にも1m程度の津波が来るという注意報が出てる。侮らないで。1mは、ふつうに自動車が流されるレベルです。画像は拾い物だけど、これが本当だから。沿岸地域の方、特に気をつけて！

On X, Masaki Nobushiro posts a recurring (and useful) drawing about how people wrongly think a 1m tsunami is a cresting wave when it's actually a wall of water filled with dangerous and deadly debris that's strong enough to sweep up a car.

In this PhD work Chris Harper investigated thin-layer stability (i.e., why a granular flow friction depends on its scale when the flow thickness is /10*characteristic diameter), which makes levees in most geophysical flows and is a process observed even in frictionless systems! #granularflows

Volcan de Fuego is at it again (#Guatemala). Follow the official information www.insivumeh.gob.gt

Why using matlab sucks... no way to activate Matlab's licence, it has now been a week @matlab ; this is why I only code in python these days...

On this day in 1902, Montagne Pelée (Martinique) unleashed pyroclastic flows that killed over 28,000 people. That tragedy gripped me as a child and led me to volcanology. After more than a decade studying PDCs, I’ve received on this day my permanent faculty post at Edinburgh to continue the journey.

Volcan de Fuego woke up after a nap of 7 weeks... watch live at www.youtube.com/watch?v=zpqT... and keep informed with insivumeh.gob.gt #Guatemala

his partner did it last summer. feel free to ask him

Sylvain mentioned to me that staying on the France side with bus (?) access was half price.

Passage from Carl Sagan’s 1995 book, the demon haunted world. The passage states “ not explaining science seems to me perverse. When you’re in love, you want to tell the world. This book is a personal statement, reflecting, my lifelong love affair with science. but there’s another reason: Science is more than a body of knowledge; it is a way of thinking. I have a four boating of an America in my children’s or grandchildren’s time - when the United States is a service or information economy; when nearly all the key manufacturing industries have slipped away to other countries; when awesome technological powers are in the hands of a very few, and no one representing the public interest can even grasp the issues; when the people have lost the ability to set their own agendas or knowledgeably question those and authority; when, clutching our crystals and nervously consulting our horoscopes, our critical faculties decline, unable to distinguish between what feels good, and what’s true, we slide, almost without noticing, back into superstition and darkness. The dumbing down of America is most evident in the slow decay of substantive content in the enormously influential media. The 30 second sound bites (now down to 10 seconds or less), lowest common denominator programming, credulous presentations on pseudoscience and superstition, but especially, a kind of celebration of ignorance.

The seismic swarm in Greece gets more complicated New data reveal unexpected volcano-tectonic interactions

🧪⚒️

The seismic swarm in Greece continues - and GPS stations on Santorini show that the island itself is deforming, signaling likely movement of magma deep in the crust. In our latest post, we explore a new detailed seismic catalog and come up with a possible interpretation.

Just a few more days until the deadline (Feb 17) to apply for the 3.5-year fully funded PhD scholarships in GPU-based modelling! 🚀 Work at the cutting edge of #granularflow and #CFD, pushing the boundaries of #EarthSciences. Don't miss this opportunity! #STEM

Artificial intelligence is proving a game changer in tracking the Santorini earthquake swarm - British Geological Survey An online tool that shows which roads are most likely to cause river pollution is being expanded to assess pollution from agricultural areas.

With geoscientists keeping a close eye on the seismicity around Santorini over the past couple of weeks, this work by the BGS using machine learning to enhance detection & short-term forecasting for advising emergency services & at-risk communities is fascinating: www.bgs.ac.uk/news/artific...

Doing Science in 2025 is fascinating...

Comparison of model-predicted and observed global surface temperatures by Zeke Hausfather

I've been encountering over the past few days the claim that the planet is warming twice as fast as predicted. This is entirely untruthful and unhelpful.
The planet is warming AS fast as predicted, which is cause enough for dramatic action.

The truth is bad enough!

A graph of atmospheric carbon dioxide concentrations at the Mauna Loa observatory, Hawaii, from 1958 to 4th February 2025. It shows carbon dioxide levels rising at an accelerating rate over the decades. This is known to be due to emissions of carbon dioxide from human activity, mainly fossil fuel burning but also deforestation. The first CO2 concentration value in March 1958 was 315 parts per million (ppm). The latest daily value is 426 ppm. The graph also shows a seasonal cycle of a few ppm within each year, which is known to be linked to the growing season in the northern hemisphere causing a temporary uptake of carbon in spring and summer and release in autumn. The graph is produced routinely by the Scripps Institution of Oceanography, UC San Diego.

Although NOAA's page on atmospheric CO2 levels has vanished, you can still get this vital information from Ralph Keeling's team at the Scripps Institution of Oceanography, UC San Diego keelingcurve.ucsd.edu

Earthquake swarm beneath the Aegean Sea Greek government is responding to elevated risk of large earthquake

🧪⚒️

A swarm of earthquakes has been rattling the Greek islands. Today marked the largest event in the swarm so far (M5.1). Schools are closed and emergency crews have deployed.

Could the swarm trigger a really big earthquake, like the M7.8 in 1956?

From the Volcanoes community on Reddit: yes, that is one happy man that has been disensitized of volcano by simply living in indonesia Posted by plentongreddit - 1,166 votes and 35 comments

Check this out... I reckon drones should be used for gathering such intel...😐 #tooclosetodanger #volcano #multiphaseflow

Unreal!

Volcan de Fuego is VERY quiet now, for the 6th day in a row... #Fuegovolcano #guatemala

Same!

did you run into our colleagues from Roma? They are there too doing high-speed imaging

got 19 and in my 30s, I think 4 is super low :)
