A ~rectangular block of dark green gray rock with lots of white blocky big minerals (many of which have darker cores). Hand for scale.

Big plagioclase phenocrysts in Catoctin Formation greenstone (meta-basalt). Rip-rap boulder below dam at Walnut Creek Park. ⚒️

The paving in a church portico with a geometric pattern in green Connemara marble, red cork marble, white Carrara marble and a grey marble.

Paving blocks in grey penmaenmawr granodiorite

Encrusting Bryozoa in grey Carboniferous limestone.

Polished Wicklow granite.

A very nice afternoon well spent on a geomooch looking at the #urbangeology of #Dublin with Patrick Wyse Jackson

That time I actually put in the work to see if a 2nd Century Chinese seismometer would function:

(The answer is yes! But the modern reproduction doesn't actually work (it's been tested) so something in Hou Han Shu description is off.)

Stopped here once, about the same year. It was fun. ⚒️

March 1, 1872, #Yellowstone becomes the first national park of the #US
(1888 geological map by American geologist Arnold Hague)

It got to 84F at my station with a 67F dewpoint! I few like I’m in Hawaii after a storm!

Photo of old paper seismogram showing ground shaking from the M6.8 Nisqually earthquake as recorded near Victoria, BC (150 km away).

Map showing how people across greater Victoria felt shaking from the 2001 M6.8 Nisqually earthquake (150 km away). Colour coding is used to distinguish between weak shaking and moderate-strong shaking.

The 2001 M6.8 Nisqually #earthquake was felt by most people in southern British Columbia, and was well-recorded (even on old paper drum recorders). Damage in #Victoria included broken windows, broken pipes, and items knocked off shelves.

Ablation profile obtained using laser with a tophat and b Gaussian intensity distribution. The measured beam profiles of both lasers are also shown on the ablation profile with red curves. The scale of the CT scan and beam profile measurements are adjusted to be the same. Variation of beam size, crater size, and energy efficiency are shown in c tophat and d Gaussian intensity distribution.

Bone cutting laser!
No, seriously, this is actually an issue (and advantage) with using lasers in surgery; they don't cut bone well. Making the laser more powerful could damage tissue, but changing its shape seems to do the trick. 🧪 #SciFiScience

The final boss of volcano vistas 🌋⚒️🧪

Welcome to March with a dramatic image of Yosemite Valley in California, USA from the Geologists' Association 2026 calendar taken by Karina Ibanez, which was Highly Commended in the GA 2025 Photo Competition.

Screenshot of my raspishake seismometer signal after the m6.3 Fiji Islands earthquake

Great signal on my Raspishake seismometer following the M6.3 #earthquake at Fiji Islands tonight. The seismic waves arrived appropriately 19 mins after origin time at my Raspishake located in Herne, Germany, 16600 km away from the epicenter! ⚒️🧪 @raspishake.bsky.social

Looks so tasty!

Yikes!

Go for it!

Love all the arts classes!

Yeah! I am truly impressed by the variety this question invoked!

😍

Thanks, Bill!

Damn, bro!

Nevermind the jobs you had, tell me five classes you took in college:

Linear Algebra
Nuclear Physics (don’t ask)
Engineering Geology
Optical Mineralogy
Field Geology

Congratulations, Robert!

Congratulations, Tim! How exciting! Wishing you the very best.

Horrifying!

A timely resource. Thank you, Peggy!

Cutting edge science- fascinating! Thank you!

Holy cow!

Love it!

Thank you!

Well, I’m no expert, but it seems that’s a bit far off for all of the phenomena you experienced! Amazing!
