Rugosa corals, right? This very stone was paved under the rotating door of the entrance of my dietician's office* (note the parallel lines). I rotated with the door to take these pics.🤣 #urbangeology *yes I lost weight. And then, slowly, I gained them back.

Not one, but TWO paroxysmal eruptive episodes at #Etna 's Northeast Crater on 27 December 2025, AND minor activity at the Voragine crater. Though the Northeast Crater has frequently shown minor activity in recent decades, its last paroxysmal episode was on 27-28 March 1998.

Big #earthquake with a magnitude of M6.6 offshore east of Taiwan a few minutes ago. Here's the seismic signal of my Raspishake seismometer 12 mins after origin time in Herne, Germany, which is 9400 km away from the epicenter. 🧪⚒️ #geology @raspishake.bsky.social

I'm super excited for the AstrHori 25mm 2x-5x macro which I just ordered for just ~130 € during the Christmas sale! #Photography #Macro #Fujifilm petapixel.com/2024/01/18/a...

For #FossilFriday here is some #UrbanGeology. Visiting York Minster but my eyes were drawn to C18 memorials with very dark limestone and lovely #fossil #corals.

Help, fellow geo people! The Other Geologist and I both got stumped by a rock my uncle has. He has no idea where it's originally from; it was just decorative in a garden before he got it. Grains/crystals are too small to see, and it's dense and sturdy, not fissile.

Merry Christmas everyone! 🎄⚒️ @berkeleymews.bsky.social

We'd have loved to share this at #AGU25 With marine terraces (4767 platforms 🖱️💪Nina!) spanning the last Myr we show that the faults of the Noto Peninsula EQ started slipping around 300 ka. A landscape evol. model explains the transient topography of the peninsula. 1/3 doi.org/10.1029/2025...
