Just paid £289 for one night midweek in London so I am really feeling for the hard times they have stumbled on

I really wish we'd stop calling them climate "skeptics" or "vaccine skeptics", if you jump off a cliff we don't call you a "gravity skeptic"

This week I get the chance to present at the Rock Slope and Gravity 2025 (RSG-2025) Conference: Forecasting and Modelling Large Rock Slope Failures in a Changing Mountain Environment. Lots of interesting talks: wp.unil.ch/rsg-2025/pro... It has an option to attend online.

The Ringways Map is here The wait is over! The full map of the Ringways, London’s unbuilt urban motorway network, is now online. Not even the system's planners had anything like this.

New! After eight years of waiting, they're online! See London's unbuilt motorways as even their planners never could in our amazing, immersive Ringways Map, hosted by the amazing SABRE Maps. It *might* be the best thing we've ever done. #ringways

Screenshot of my raspishake seismometer signal after the M3.4 earthquake in Groningen, Netherlands

Tonight, the Groningen region in the Netherlands was shaken by a magnitude 3.4 #earthquake, according to KNMI. This is the biggest eq in the region in the past 6 years. Here's the seismogram from my Raspishake in Herne, Germany, 211 km away from the epicenter. 🧪⚒️ #Geology

Terzaghi, a structural engineer specialized in the design of dams, recognized the necessity to consider also the geological surrounding of where a dam was to be constructed. After a project for a dam failed, he invited geoscientists into his team.

Lotus's decision in the 1980s to convert its DOS products to OS2 rather than Windows, little remembered today, was one of the truly catastrophic mistakes in modern IT history. Lotus opened the door wide for Excel and Word, and relegated itself to the dustbin of history.

Keir Starmer tells his Cabinet that scenes of police under attack at a march "led by a convicted criminal and egged on by a foreign billionaire calling for violence" sent "a chill through the spines" of British people.

In good but unexpected email news, the widow of the late Robert Mugabe has cherry-picked me to manage $87,500,000 in investment funds.

Reform UK further enhance their image as the party of ordinary people by welcoming Danny Kruger, the Eton/Oxford educated son of multi millionaire parents.

Earth science departments are being gutted across the country, which is utterly bizarre given their relevance to our understanding of climate, hazards and disasters, the soils that feed us, the industries that drive our economies, and the importance of ancient life to understanding biodiversity.

He used the word "la giologia" - geology - for the very first time in 1603, describing it as "the study of all things related to Earth."

If you vote Reform you will be voting against women’s equality, for more harassment in the workplace and beyond (as if there isn’t enough)

Remember 41% of the Farage Foot Soldiers arrested in last summer’s disgraceful riots had already been REPORTED FOR DOMESTIC ABUSE

If these people are filmed or seen by the police painting flags kn roads etc can we expect police to investigate and prosecute, as was done with PA when they painted a few planes? Surely their ideology - and we all know it's not just innocent patriotism - makes them more of a threat?

All these right wing patriots fervently putting flags up everywhere seems somehow familiar...

Geology of Milan-Sanremo | Geo-Sports We explore the geology of Milan-Sanremo with lost oceans, colliding continents plus a bit of risotto and wine.

So, some background for the start of @lavuelta.bsky.social…and oddly, the best way to do that is by telling you about the geology of Milano-San Remo 😃. The first days will be about the Po Plain and the Ligurian Alps! Enjoy!
