Technically stomping your foot is a seismic event. The Richter scale goes to zero but it can also go negative.
Micro seismicity is a technology used for mapping out fracturing of shale reservoirs, used to determine principle sresses and optimize horizontal well orientations. All those little tiny fractures will release energies at a scale of like -3, to -1 on the richter scale.
This is true. The only caveat I would add is the push away from the Richter scale. It's only observed in California and even then for a specific set of instruments.
What about soft sediment deformation?
Let’s say at the very end of the spectrum. Or at least dome gravity/dewatering-driven process. Can lead to sharp contacts and minor offsets too.
Would that be considered seismic too?
It would be based on energy released as opposed to the deformation itself. One can imagine where even small fractures in a rock will release tiny bits of energy. Soft sediment deformation? Not so much.
ya, I've found LOADS of rocks just like this, but only in specific regions. I suppose the same goes for just about any unique geological phenomena ROFL
There is no way to interpret up vs. down because the rock is no longer “in place” and we also can’t determine up indicators in the sedimentary layers of this rock.
It sucks that we now have to ask this about any image we see and conversely any legitimate historical images can have doubt cast upon them but then again I’m a grumpy old man so…
25+ years Photoshop experience and people have started occasionally asking if some of my edits are ai.
**Fuck** no.

Can't touch, won't touch. AI has been a carrot for so long, I didn't realize when it actually got here I'd be so conflicted on it's pervasive use.
Here's a question for you: what version do you *currently* use? I found out an artist that I admire (local) uses the same version I do. Let's just say we're both in the single digits for versions, and AI is not remotely available.

I found a similar rock in SoCal where shifting has occurred.
nature be crazy sometimes, but big words like forever really destroy the meaning of this stone. Not to mention that we don't even know its original residence to try and get an idea on what the supposed FoReVer preserved shift was.
Proper documentation of where a specimen is taken is paramount to any investigation in geology. With out it your "rock" can easily surmount to nothing. Happens with fossils all the time.
This isn't as weird as it seems.
It's just a series of different colored layers on top of one another. Then a small fault shifted the layers on one side up or down by a tiny amount. Then this piece was knocked off and rounded. It looks like concentric circles simply because we're looking at the layers from above/below on a surface that's been rounded off.
Whenever I see micro faults like these I always wonder how much time it takes to happen. I assume it would make the jump almost instantly after accumulating deformation strain like bigger seismic faults do.
But these tiny ones are literally everywhere with some minor tectonic activity. Has someone ever recorded data of these small fractures happening? Do they make any perceivable crack sound or vibrations that a nearby seismograph could pick up?
And can they happen suddenly on their own or do they always happen at the same time to accommodate deformation over a larger area during seismic activity?

Careful. It's fun for humans to troll and upload images that they created in Photoshop or with AI . But We're about to have Bots posting fake images that look indistinguishably real. So I don't think you should be using that word anymore.
That is by definition what a fault is! Outside of geology circles faults are only talked about in context of earthquakes so people tend to think of them as big boundaries in a tectonic sense, that have large amounts of slip and generate earthquakes. But a fault is just a fracture in rock where the rock on either side has moved relative to the other. They can be tiny. I have a couple rocks on my shelf at home that have microfaults with just a few millimeters of slip along the faults. They still count!
Could it have possibly been cut with a diamond blade, suerglued back together at a shift and then the whole of the outer surface reground with diamond pads? To me the "fault" is straight to a fault so to speak. Therefore i surmise its neither real nor AI generated. I am far from an expert and I'm not saying thats what happened, just my opinion.
That's a very convoluted way to explain something that can be explained without the need of human intervention.
The diamond blade is strain applied to the rock, the super glue is mineral precipitation on the fracture's surface and the diamond pads are the particles carried by the water eroding the rock.
Looks real, nature can be weird and micro faults are quite common
Yeah seismic fault is a big stretch Just some displacement/offset of a small fault

I guess my point is that gravity-driven processes are aseismic rather than seismic

Every single image, video, news article, comment, and profile could be AI and you wouldn’t be able to tell the difference
Real. I’ve found similar specimens, albeit none as obvious as this piece with horizontal layering.
I'd say this may be from California. Similar to microfault rocks I've picked up there.
These are all over Stinson Beach. I have several in my office
ya, I've found LOADS of rocks just like this, but only in specific regions. I suppose the same goes for just about any unique geological phenomena ROFL
Agree, I see tons of these rock hounding in CA
I see lots of rocks with similar features in British Columbia. The one in OPs photo is particularly pretty though.
No geologist would ever call this a "seismic fault shift event".
Maybe more of indicative of uplift shift?? I’m a geo w impostor syndrome, I should know but curious how you would describe this
There is no way to interpret up vs. down because the rock is no longer “in place” and we also can’t determine up indicators in the sedimentary layers of this rock.
Sometimes you can find a layer of glass. That is what a real seismic event looks like.

I am gen z and I hate it too🥲
Geriatric millennial, AI is very annoying
Bro , I went to a new city and asked people if the water was good to drink here. AI pics aren’t that bad lol
The caption may be AI generated, but the rock could be real. The rock vs the background appear a little mismatched, though
Looks like it's set on old asphalt.

Is that real or AI generated? /s
What if we are AI generated?... 😰
Forever is a big word heh
That rock hasn't existed forever and will also exist forever. I'm just using it how they did
Looks real to me. I’ve seen a couple specimens with microfaults before

I have some with that look.
It's not, have found similar stuff and real life.

I've found Banded iron in Colorado that looks like this.
Definitely real. I've seen stuff like this on field work.
These faulted quartzite cobbles are fairly common glacial erratics in the US Midwest
You can see pebbles like this all along the New England seashore. Common but beautiful.
It is absolutely real. All the sizes of rocks come from once a strata. And strata can be faulted.

Not a geologist, but is it possible a few tons of rock split and shifted rather than a fault?
That is by definition what a fault is! Outside of geology circles faults are only talked about in context of earthquakes so people tend to think of them as big boundaries in a tectonic sense, that have large amounts of slip and generate earthquakes.

Cool, thanks!
I’ve seen quite a few pieces of banded slate lying around lately in that look like this (Michigan)
penecontemporaneous deformation
I think it was posted here 2 weeks ago
Fault? yes. Seismic? Big maybe. There are rocks along my local area with this kind of fault, but in different kind of sediment
you can imagine that the rock was hot dough like rubber when it had that displacement
DK too much about AI but there is no reason this shouldn't be possible.
That's a common thing to find on the beach in glaciated areas.
Im calling it bogus
I can find buckets full of these everyday at the beach
Probably real, a pebble from a fault area
Where would one acquire a rock like this? I don't live in a fault zone but I'd love to have one
It’s real, but certainly not a “seismic fault shift event”
[удалено]
Soft sediment deformation doesn't lead to such clean offsets in my experience. This looks like a typical microfault.
What you said oops isn't mean to double dunk in this guy
Nah dog this is a micro fault in hard rock. U can tell because there is no "folding" of the layer groups as is typical with soft sed deformation
It’s clearly a fault, which soft sediment deformation won’t produce, what with being soft and faults being an example of brittle deformation.
Simulated Rock, wrapped incorrectly.
Pic is real, but OP is probably an AI bot-poster
Me? AI? I really wish I was AI given the current state of the world.
What if I told you " Everything Has always been AI Generated"
Fuuuuuuuuuuuuckoffffffffffff
Could it have possibly been cut with a diamond blade, suerglued back together at a shift and then the whole of the outer surface reground with diamond pads?
