📣New paper out!🔔 We quantify deep/viscous subduction interface rheology by integrating field observations, numerical models, and experimental flow laws. This provides us new insights into viscosity and strength variations along subduction zones. 1/3 researchgate.net/publication…

I'm currently working on massive panoramas of our skies. They're more work than traditional astrophotography images, and are forcing me to learn a lot about the craft. Here's a small segment of one of them, showing the neighboring Andromeda galaxy. The color is 100% accurate.

New paper out on blueschist deformation experiments!!! 🚨🚨🚨 From the exps we developed a flow law and some of the first rheological constraints on diffusional properties in amphibole. @sgt_ethz . Check it out #OpenAccess #microboudinage agupubs.onlinelibrary.wiley.…

Diffusion Creep of Sodic Amphibole‐Bearing Blueschist Limited by Microboudinage

Experimentally deformed sodic amphibole deforms by microboudinage with sodic-calcic amphibole diffusing into the boudin neck We developed a microboudinage flow law with a stress exponent of 2.0 ...

In #Switzerland, a very large, incipient rockslide has triggered the evacuation of the village of #Brienz (Brinzauls):- blogs.agu.org/landslideblog/…

Watch this, and tell me you did not feel something. Football fans in Turkey throw toys down on the field to collect for the children in the earthquake zone. Such a beautiful and heartwrenching scene of love. Such big hearts.

This is hilarious. Aldi created an Amazon-like “grab and go, zero staff” store in the Netherlands. Except no customers enter b/c to do so, you need to register *with a credit card*. The majority of the population in the Netherlands doesn’t have a credit card! They have debit.

Aldi introduced an Amazon-like store in The Netherlands. You can grab your groceries and walk out. Cameras register what you take & auto-charge your creditcard. Zero friction. Except in a country where ppl don’t have creditcards & your app sucks 🤦🏻‍♂️

A swarm of earthquakes has rattled under the town of Pahala, Hawaii, for decades, surging to hundreds of quakes a week in 2019. Now scientists finally pinned down the source & mapped the island's underbelly. And he data are just WOW. My latest @natgeo nationalgeographic.com/scien…

Scientists just mapped Hawaii’s volcanic underbelly in stunning detail

A groundbreaking seismic study has uncovered a vast web of magma reservoirs some 25 miles beneath Hawaii. "My mind was just blown."

The Open access movement: Why OA? In case you haven't watched Christie Rowe's SCEC talk, it is a great jumping point into the OA movement and to Seismica's why and how: youtu.be/K5UVUVt9GAM?t=304 #OAWeek2022 #DiamondOpenAccess
