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

[–] AnotherPerson@lemmy.world 0 points 2 years ago (2 children)

Ahh yes just what we need. More toxic gases being vented into the atmosphere. I'm sure it will be fine.

[–] Pons_Aelius@kbin.social 1 points 2 years ago (1 children)

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

[–] MercuryUprising@lemmy.world 1 points 2 years ago

Very unlikely that something like the biosphere and geology are connected symbiotically.

[–] mostNONheinous@lemmy.world 0 points 2 years ago (2 children)

I’ll take what the earth spits out versus what we put out.

[–] NewSmileadon@lemmy.world 0 points 2 years ago (1 children)

What if the earth ignites all the untapped fossil fuel and releases it into the atmosphere?

[–] mostNONheinous@lemmy.world 0 points 2 years ago (1 children)

One hell of a show that’s for sure.

[–] NewSmileadon@lemmy.world 1 points 2 years ago

I guess that's all we could say

[–] PaulDevonUK@lemmy.world 0 points 2 years ago

The earth has been doing that for thousands of years.

We are the culprits, not the planet.

[–] Typeo@lemmy.world 1 points 2 years ago (1 children)

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.

[–] Nepenthe@kbin.social 0 points 2 years ago (2 children)

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.

[–] meldroc@lemmy.world 1 points 2 years ago (1 children)

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.

[–] Mrk421@kbin.social 1 points 2 years ago (1 children)

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?

[–] Holyhandgrenade@lemmy.world 1 points 2 years ago

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.

[–] Holyhandgrenade@lemmy.world 1 points 2 years ago

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.

[–] johnrock123@futurology.today 1 points 1 year ago

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.

Doesn't increased volcanic activity cause an increase in global temperatures?

[–] badragonfly7137@lemmy.fmhy.ml 1 points 2 years ago

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.

[–] meteotsunami@lemmy.world 1 points 2 years ago

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).

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.

[–] Holyhandgrenade@lemmy.world 1 points 2 years ago

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! 😂

[–] onoki@sopuli.xyz 1 points 2 years ago

For ages = for one week in the Central Europe. I had a trip booked for roughly exactly the duration of the eruption back then.
