…and how much like k-feldspar they can briefly create very small amounts of antimatter whose annihilation can be detected. Let a detector run for 2 hours next to a pile of spicy-ish amazonite and got a few detections of 511 kev. Want to make sure the premise of my video isn’t wrong. (2/2)
Thanks for your reply. So it’s safe to say that beta+ (not beta-) decay (very briefly) produces antimatter (positron) before it annihilates itself (in positronium) with an electron (in under 1/5,000,000 of a second), thus generating (typically) 2 gamma rays? Making a video discussing bananas…(1/2)
I thought k-40 had a 1 in 100,000 chance beta+ pathway. Even measured a few instances of such with a highly sensitive 2 hour exposure
Question. Are antineutrinos a form of antimatter? If so, doesn’t that mean that all beta (radioactive) decay creates antimatter (briefly)? So a banana would (very very rarely) produce antineutrinos or positrons? Seeking clarification from a physicist. #physics #geology #isotope #science
@borisetneo.bsky.social are you more active on here or X? Have a geology opinion question to ask you.
I am requesting assistance in geolocating where exactly “Tarasin village” is in Sudan. I’ve been attempting to geolocate for 2 hours now to the north, northeast, or east of the Jebel Marra volcano with no luck. This is so I can make a video discussing the #landslide. #geolocation
This has been known for some time; although regarding how much of an increase depends on ice cap thickness and magma chamber depth
There’s some weirdness in regards to this. Because the Maya seemed more severely impacted by the 535-540 CE extreme weather events / volcanic winter
Asking for part of a future video I want to make; have there been any paleontology, interesting fossil finds/interpretations, or paleogeology finds in the last 5 years that would count as major discoveries? I already know of the recent discovery explaining the lack of mid sized dinosaurs.
Ah, perfect. That sounds about right too. I just assumed that the prior events didn’t coincide with tourist season and occur during nice weather.
Assuming PDC was similar volume. I’ll cite you on this figure for my Sunday video :).
How does this compare to other small scale collapses etna has produced in the last century? I’m curious how much slumped or was cut away by the paroxysm / pdc
My younger cat disses me by licking wherever I had just pet him. #cat
I don’t think anyone noticed, but India’s Barren Island volcano is erupting again. #india #geology #volcano
Question. Other than Papua New Guinea, what countries do we not truly have a good idea of what the current population is?

For some reason the defense.gov website states that just under “420,000 Japanese” were killed in the battle of Leyte Gulf. It also gives a horribly inaccurate total for American casualties in that pivotal ww2 battle.

Opinion; moving Indonesia’s Awu volcano from slight to moderate unrest in my personal volcanic unrest scale. (Scale goes from no unrest, slight unrest, minor unrest, moderate unrest, to significant unrest). #awu #indonesia #volcano
Any questions regarding the Myanmar / Burma earthquake? Looking for questions to answer in tomorrow’s video
Usfl is fun, don’t worry I watch every game given the chance.
(Meant arena football league game)
(American) Football fans, I am looking for some advice. Is there a legitimately reason to attend an Arena football league, or is it still a shitshow like it was 1-2 years(?) ago.
The 3 story pillars were the point of failure (or so it seems), and while I could be wrong here they didn't look reinforced. That design should have never been built in my opinion. In other words, normal skyscrapers don't collapse when they experience such weak / moderate shaking. And yet... (2/2)
That Thailand (Bangkok) skyscraper in my opinion was poorly designed and shouldn’t have collapsed after only experiencing MMI IV (4) shaking. It is a classic example of a soft story building. (1/2) #thailand #bangkok #earthquake
We sadly have our first confirmed direct volcanic eruption fatality of 2025. Cause: burned by pyroclastic surge 5.2 km away from Lewotobi’s Laki Laki cone summit during its major eruption last week. :(
When discussing economic damage caused by volcanic eruptions, should I remove “lost business” (example, flights are grounded but no damage occurs)? I worry including them in comparison graphics can make the charts very west-centric when other world volcanoes can also be quite dangerous.
It appears that the Lewotobi volcano produced a very large explosion. Details upcoming.
I am planning on making a video on what to do as precautions during light to moderate ashfall during a volcanic eruption. Precautions for gasoline engine cars are already known to me. However, what I do not know is what precautions must be made for purely electric vehicles?
lol silly
