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
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.
I’ll take what the earth spits out versus what we put out.
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
The earth has been doing that for thousands of years.
We are the culprits, not the planet.
I wish this message discovers you well. We are sorry to educate you that an advancing surge has actually started in Iceland, with approximated magnitudes going beyond previous occasions tenfold. This growth might have substantial effects for numerous local markets along with services. For those looking for understandings or advice in the middle of this dilemma our group prepares to give Business Report Writing Help customized to attend to particular issues as well as minimize possible threats.
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'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.
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.
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.
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! 😂
For ages = for one week in the Central Europe. I had a trip booked for roughly exactly the duration of the eruption back then.
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.

Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- 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.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
-
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.
