Earthquake Prediction Flowchart

xkcd.com/3165/
Comic. Someone is claiming to predict the exact date of a future earthquake. Should you listen? [flowchart: start] → NO (There are big earthquakes constantly, so if anyone ever *does* figure this out, it will be immediately obvious that their method works and then the world’s seismologists will not shut up about it. You won’t need this flowchart.)

There's something that feels a bit dead about the world right now, but tens of thousands of people just came together to help us solve a 100 year old mystery about a little blue jelly, and I find that heartbreakingly hopeful:

Copper crystals can form beautiful leafy patterns called dendrites from the Greek word dendron meaning tree. Dendrites grow due to mineral-rich fluids moving through cracks or during rapid cooling from a melt or vapor. Vote and more👇🏼

Heart Mountain

4-panel comic. (1) PERSON 1: We haven’t checked in on the geology department for a while. I wonder if they’re doing okay. (2) PERSON 2 with ponytail: I’ll go see what they’re up to. (3) [Person 2 opens door to room where a person is gesturing at a projector screen and explaining to two other people] PERSON 3: 49 million years ago, Heart Mountain, Wyoming slid sideways 15 miles like a giant stone hovercraft. (4) PERSON 2 [returning to Person 1]: ...They’re not okay. OFF-PANEL PERSON: Hey, *you* come up with a better explanation!

This morning's capture of Comet C/2025 A6 (Lemmon)
The comet will make its closest pass to Earth on October 21, 2025, at a distance of about 55 million miles (89 million kilometres).

Comet C/2025 A6 Lemmon showing a big kink in the tail this morning. This is a stack of 5, 60 s exposures with a Takahashi TSA 120 and 0.7x reducer and Sony Alpha 7 III. Will try to get more images tonight and some good flats. #astrophotography

Piglet squids (genus Helicocranchia) are a genus of small cranchiids known for their goofy appearance. They have a rather large siphon that make them look like a pig with a snout.

Well I guess with their arms raised up cranchiid style, they look like a pig with a crazy hairdo.

#SQUIDtember
A piglet squid (Helicocranchia sp.) floating in the ocean. Its entire body is translucent and is oriented horizontally. Its limbs being held upwards, making it look like it has crazy hairdo. It has a relatively large siphon that is below its head sticking straight out, making it look like a pig with a snout. The picture is from the side. Two In situ photographs of the same female piglet squid (Helicocranchia sp.), anterolateral views, from an ROV photographed floating in front of oil pumping equipment in the Gulf of Guinea at a depth of 1015 m. Arrow in upper photograph points to stub of tentacle. The squid is a slightly translucent beige pink. Its limbs being held upwards, making it look like it has crazy hairdo. It has a relatively large siphon that is below its head sticking straight out, making it look like a pig with a snout, especially since the opening is closed in a way that resembles nostrils. A piglet squid (Helicocranchia sp.) swimming in the ocean. Its limbs are spread out and pointing up, and its mantle is going back. It has black eyes and its siphon is large and going past its head, making it look like a pig with a snout. A floating piglet squid (Helicocranchia sp.). Its body is completely translucent, except for a single, thin, vertically oriented organ. Its limbs being held upwards, making it look like it has crazy hairdo. It has a relatively large siphon that is below its head sticking straight out, making it look like a pig with a snout

Best glory I’ve ever seen from a plane! It’s an optical phenomenon that occurs when light interacts in and around tiny droplets of water in the clouds, in the direction opposite the sun. More complex than a rainbow. Here’s a link to some more info: www.zmescience.com/science/phys... #optics #physics

Did you know that England's oldest fee paying attraction is geological?

It starts at this unassuming spring, rich in sulphate and carbonate which precipitates tufa.

The spring disappears into the ground and then reappears in a waterfall that turns things to stone. ⚒️🧪🪨🌍🧵
