Professor of Geology @NjordUiO @UniOslo. I love #shearzones, #faults, #EBSD, mountains, travelling, wine, @juventusfc :) 🇪🇺🇮🇹⛰
Oslo, Norway
Joined March 2013
🚨👇How much plastic damage does a deep #earthquake produce?We measured residual stress in exhumed seismic faults with HR-#EBSD and calculated the energy budget of the earthquake. Nice work, thanks @EXCITE_network and @forskningsradet! ⛰️🔬

The earthquake energy is consumed on-fault by frictional heating, fracturing, and crystal lattice straining.

Hi all, I will no longer be active on Twitter/X. If you wish to stay connected, I’ll be happy to see you on other social media. Best wishes, Luca

Very good catch of the day doing #fieldwork on faults and shear zones in the subduction channel, where fluids were passing through rocks from the Earth’s mantle. Enjoying #geology and stunning sceneries with great crew of friends and colleagues from @Unibo

Thanks @DFT_UniBologna for the kind hospitality and for all the good discussions!
DFT presentation Thanks to Prof. @MicroLuca (University of Oslo) for his insightful seminar on the geology of the lower-crustal #earthquake in Lofoten (Norway), with a focus on the genesis of #pseudotachylyte at the DFT group meeting. #structuralgeology #metamorphism

Now the question is: has Gemma really found a mini-sample of the Calabrian #pseudotachylyte in her daily rock hunting session on the beach??

The lower crust is strong and can generate earthquakes during continental collision. This happened 420 million years ago, when Baltica and Laurentia collided to form the mighty Scandinavian Caledonides. Watch @sheared_sash telling us how it happened. 👇🎬🎥⛏️🔬⛰️
Straight from the Goldschmidt Lab at UiO we present to you @sheared_sash giving a rundown on his latest paper: Dating fossil lower-crustal earthquakes by in-situ apatite U-Pb geochronology https://t.co/XrMG6Av3dl Enjoy!! 🍿 🎥

It has been an incredibly inspiring and exciting June so far, discussing #earthquakes, #tectonics, #geophysics, #microstructures and other cool things with wonderful colleagues from around the world, first in the magnificent #Lofoten and then at @DNVA1, thanks everyone! 🤩⛰️🔬

Yesterday was our Njord Day - a day of light science, art, and culture. What a beautiful day to celebrate our diversity and interests!

Another year of @EuroGeosciences comes to a close. Our ECS showcased Njord’s strengths in understanding earth processes brilliantly. A week full of strengthening connections, meeting new people, and developing skills. Can’t wait for next year! #EGU24

Hello @EuroGeosciences! We are looking forward to seeing you again soon for another cool week of science and networking in the beautiful Vienna.
Off to Vienna for #egu24 ! Many ECS members of our Njord family are giving presentations on glacier dynamics, molecular dynamics modelling of fractures in basalts, fracture experiments, and microstructures on fault rocks from the lower-crust. Check them out and see you in Vienna!

I had a great time in Turin teaching orogenesis and applied structural #geology in the last two weeks! A lovely city in the cradle of the #Alps. Thanks @rodo34751929 for the kind hospitality, maybe next time in Norway to look at the #Caledonides 😊⛰️🔬

Nice work that managed to date lower-crustal fossil #earthquakes from Lofoten for the first time, combining U-Pb on apatite with #EBSD and CL. Lower-crustal faults and shear zones are preferential fluid conduits in the otherwise dry lower crust even long after they formed
We have an age! Check out our latest paper on dating lower-crustal earthquakes! We combined apatite U-Pb data with microstructural observations (EBSD, CL). Open access! @MicroLuca @NjordUiO

There we go, I couldn’t resist and played with my Google Scholar Wordcloud 😅 Cool! https://t.co/7kXT4dbJ5f

🚨Nice piece of work collaboration with @deep_carbon. In a nutshell, methane and hydrogen rich fluids can produce fluid overpressure, potentially leading to subduction zone earthquakes, more easily than just aqueous fluids. Cheers 🍻

Hot off the press, well actually still on it! Check out our new paper on a shear zone that re-uses a fabric for a really really long time! @NjordUiO @MicroLuca
