A very, very, very very very very very very very very very, very polished fault surface reflects the blue sky
The insane, mirror-like shine of the Corona Heights Fault. ⚒️

Fossils. The smaller pieces are about 1 cm long
Coral fossils
Other type of coral fossils
Fossils of bivalves
Bit late for #FossilFriday, but I just found time to clean the #fossils we found on our last trip to Nettersheim. They are from a reef environment from the middle Devon (about 380 million years old). I am not an expert but I like how well the little structures on the surface are preserved. ⚒️

Great signal on my Raspishake seismometer following the M5.5 #earthquake at the Greece-Albanian border tonight. The seismic waves arrived approximately 4 mins after origin time at my Raspishake located in Herne, Germany, 1700 km away from the epicenter! ⚒️🧪 @raspishake.bsky.social

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!

05.01.2026 00:40 — 👍 1 🔁 0 💬 0 📌 0Yikes! That you heard MSH’s is amazing. BTW, you’re not wrong about California. Many towns are within susceptible distance to volcanic hazards from potential future Lassen eruptions.
