I live about 30 minutes away. We've had a lot of earthquakes the past few days. This should shut them up :) Some scientists say we've entered a period of very frequent volcanic activity for the next 100 years or so in this area.
Oh, that’ll be good for home prices in the area I imagine.
Finally millennials can afford housing
Depends on if you are selling or buying
Or a repair company!
Ahh yes just what we need. More toxic gases being vented into the atmosphere. I'm sure it will be fine.
Large volcanic eruptions have a cooling effect due to the large amount of aerosols injected into the upper atmosphere.
It mimics/is the inspiration for the geoengineering idea (highly impractical at the scale required) of high altitude aerosols injection to slow global warming.
Are you saying that earth might be defending itself against our aggression? Interesting
Very unlikely that something like the biosphere and geology are connected symbiotically.
Although there is a connection between geology and climate change (not that I think this is part of it). https://climate.nasa.gov/news/2926/can-climate-affect-earthquakes-or-are-the-connections-shaky/
Good article, and pretty interesting stuff. That said, I can't imagine this being a "defense mechanism" for increased temperatures, as during the Cretaceous period there wasn't any increase in seismic activity that we are currently aware of.
No, it's not any sort of defense mechanism. It just made me think of that article.

I’ll take what the earth spits out versus what we put out.
The earth has been doing that for thousands of years.
We are the culprits, not the planet.
What if the earth ignites all the untapped fossil fuel and releases it into the atmosphere?
One hell of a show that’s for sure.
I guess that's all we could say
Maybe, maybe not. Fire triangle is heat, fuel, oxygen.
We can assume safely fuel and heat, oxygen is tricky though.
Explosions and ignitions only happen in a happy zone.
Too much or too little oxygen disables everything.
We also have to calculate what mix of hydrocarbons we are dealing with, how hot the ignition points are and the pressure exerted by gravity and the atmosphere.
I don't think there is enough oxygen.
Even under ideal circumstances and distribution, there is still only 21% oxygen in the air.
Propane needs 8x the amount of oxygen for a complete burn as acetylene does and acetylene in open air just produces thick greasy black strings in the air.
Idk the exact mix but I know you can barely hear acetylene coming out of a torch, but the oxygen side is loud as fuck.
Given a reasonable variance for imprecision, I feel the variance in sound levels is proportional to gas flow.
However depending on the pressure, you could need even more.
Diesel fuel is damn near impossible to light on fire at SPT, but put it under compression and it will self ignite.
We use turbos, basically little air compressors, to force as much regular air as possible into an engine, because it uses so much oxygen.
There's actually a lot of small mineral dust that are sent in the air, that can filter some sun rays and decrease the heat
Volcanic glitter ✨
These ones cool stuff in the short term (and cause acid rain, ozone depletion, famines and long term warming; and there'll probably be a new thing this time around where some countries have reduced solar output).
They also ground planes and cancel road trips.
This volcano might even save us from a blue arctic event for a few extra years, so it could be a wash in terms of climate (although definitely not for europe's ability to feed itself)
I don't mean to steal attention away from Iceland and hope you are all safe, but it's a similar thing in Japan. We're due for a megathrust earthquake that could be way way worse than Fukushima.
This bit made me laugh:
Þórdís [reporter] says people are flocking and letting the warning words of the Civil Defence fall on deaf ears. The police are also working hard to remove cars that are inside the closure area.
Þórdís and Bragi [photographer] are watching the eruption up close. However, they cannot stay there for long because the lava is expected to soon flow over the roads they used to get there.
Anything for the 'gram.
Are we going to watch news anchors try to say an impossible name again for the next week?

This is so exciting. The last time there was a major volcanic eruption in Europe, it shut down air travel for ages over there. Plus there was a cool and totally improbable scene in Walter Mitty about it.
For ages = for one week in the Central Europe. I had a trip booked for roughly exactly the duration of the eruption back then.

It was shut down entirely for a week initially, and then would be shut down again periodically as the ash/debris cloud floated along through air lanes.
Also that totally sucks.
That Walter Mitty scene made me laugh. It was filmed in Seyðisfjörður, which is around 700 km away from Eyjafjallajökull. They had even changed the map shown in the movie, so it was unrecognizable for an Icelander! 😂

I had no idea. That’s hilarious.
This is the third eruption that's occured on the peninsula in three years and it's largely died down so I wouldn't call it "exciting"
It's pretty though.

Volcanic eruptions are always exciting.
We were lucky enough to visit the last one when it erupted. Hopefully nothing major and everyone is safe.
Lava eruptions like this tend to be less dangerous than ash eruptions, which can mess up air traffic and the ashfall is bad for the lungs and crops. So I don't think there's much cause for concern.
TIL volcanoes even have two different eruptions. I just always imagined they came with ash as a given. That makes me feel a bit better about this, though I still echo their hope for as little damage as possible.
I think it depends on the particular volcanoes. The volcanoes in Iceland and Hawaii, IIRC, have thinner and less gassy magma, so there's not as much gas buildup, and the eruptions tend to have more liquid lava. Elsewhere, say Mt. St. Helens, the eruptions tend to have thick lava, with lots of trapped gas inside, that tend to cause giant explosions, pyroclastic flows & big ash clouds.
I would hazard a guess that it's dependent on even more than region. Wasn't it an Icelandic volcano that shut down air travel because of ash a few years back?
When it erupts underneath a glacier, it causes huge clouds of ash to form. The volcano you're talking about (Eyjafjallajökull) is a glacier volcano in the highlands whereas this one is on the Reykjanes peninsula on the west side.
I'm by no means an expert but in Iceland,
eruption under a glacier = ash eruption
eruption not under a glacier = lava flow.
I'm sure it's more nuanced than that but it seems to be the rule of thumb over here.
Doesn't increased volcanic activity cause an increase in global temperatures?
Typically, volcanic eruptions have a cooling effect. One of the principle emissions is sulfur dioxide which reflects high frequency solar energy (green house gases absorb and convert that same radiation into longer wave energy which excites atmospheric gases).
You can read more at the University Corporation for Atmospheric Research.
Volcanoes typically erupt with a lot of ash which blocks the sun and cools the planet. Get a big enough volcano and the earth stays cooler for years, disrupting crops and creating a potential famine.
So, what you're saying is, we can just piss off Surtr, just the right amount, and cancel global warming?
That sounds way easier than getting a giant ice cube!

Is it named Heyyafeyjakool or something?
No.
I wonder what the effect will be on climate change 🤔

- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.

Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.
