⚒️ 🧪 Were you one of the tens of thousands in the Bay Area woken up by the M4.3 earthquake last night? The earthquake occurred on the Hayward Fault, which runs along the east side of the valley. Learn more about what we know, and don't know, about the Hayward Fault and its seismic hazard:

Maples and aspens rarely peak together here, but that’s okay. I like the aspens when they are bright green! Great contrast with the red maples in peak color. #mountainmonday #nature #art #eastcoastkin #travel #autumn #naturephotography #trees #firstdayoffall #photography #botany

While molybdenite gets some physics points (source of Re for geochronology, Mo used as a catalyst, battery electrodes, alloys of iron & semiconductors), Dioptase can be made into jewelry & (though a rare pigment) has been on artwork used since Neolithic times so it wins my art vote!

We’re no fools over at Eos. For today’s #MinCup25 matchup, we’re going with brilliant, green dioptase over "fool’s silver" (molybdenite). 📸: Didier Descouens, CC BY 3.0

L'instabilité s'accentue de l'Aquitaine à la Normandie, au sein de la bande d'éclaircies qui s'est constituée, et qui gagne du terrain vers l'est. 1000 à 1500 J/kg de CAPE à 14h15 sur cet axe. Les orages devraient s'initier dans cette zone d'ici ce soir. ➡️suivi en direct : urlr.me/PNEf9q

Proof of concept! Dry tintype on 35mm film cartridge! This is so neat. Shot on the Benson Instant Box Camera I was hoping to avoid the step, but the cartridges will definitely need a subbing layer, because the emulsion is clearly not adhering well. 😅😅 #BelieveInFilm #AfghanBoxCamera #Tintype

#MinCup25 Round 2 Match 3: It's a heavyweight match between industrial powerhouses as soft #baryte competes against rusty red #hematite. Vote: www.mineralcup.org/2025/vote/r2... Results: www.mineralcup.org/2025/results...

Archaean #Baryte deposits of the Barberton Greenstone Belt provide insight on the composition of Earth’s atmosphere and crust 3.2 bya. Sulfate-bearing meteoric water combined with cold spring-sourced Ba formed Baryte deposits in sands and cherts. Fluor- and phosphorescent. #MinCup25

🔔#Earthquake (#землетрясение) M7.8 occurred 128 km E of #Petropavlovsk-Kamchatskiy (Russian Federation) 29 min ago (local time 06:58:15). More info at: 📱https://m.emsc.eu/#app 🌐https://m.emsc.eu/?id=1867502 🖥https://www.emsc-csem.org/Earthquake_information/earthquake.php?id=1867502

The moon yesterday morning. I love it when it's at this angle, like the top of a skull.

'et moneo ut quis quem vicerit occidat'. Esorto chi abbia vinto a uccidere (l'avversario). Oggi vi racconto la storia di Urbicus, il gladiatore ricordato in un'iscrizione rinvenuta a Milano e attualmente conservata nella collezione del Museo Archeologico (Antiquarium A. Levi) -> (foto da wiki)

The Cretaceous fossil goniasterid Peedeeaster sandersoni from the Peedee formation of North Carolina! A new genus/species I described a few years ago! My first fossil species! #echinoday #fossilFriday (can provide upon request) mapress.com/zt/article/v...

Tendenza. Fino a domani, venerdì, il Nord Italia e l'alta Toscana risentiranno del passaggio di alcuni sistemi frontali atlantici sull'Europa centrale. Nubi sparse e qualche pioggia sui rilievi. Sul resto d'Italia condizioni di maggior stabilità. 1/5

Next 'holiday #seaweed' is distinctive 'green sea fingers'! Three look-alike species are found in Britain. All belong to genus Codium; all are green #algae (so plants); one (C fragile) is invasive. Note peek-a-boo shrimp hiding in one photo: we'll return to them in our tour of Scottish rockpools!

More graphite sketches. I have no idea why I drew this sea stack... There's probably a reason but it's left my brain. 🤷
