Rules:

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.

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.

One thing I miss from reddit is those people who’d come in and explain everything, like that Earthquake person.

You have either ~~plutonic~~ or ~~basaltic~~ volcanoes. This is a quiet ~~plutonic~~ one : it's lava flows without explosions, so, there could be much worse scenarios. But still, it is a big one.
Edit : My use of "plutonic" might be outdated or wrong : I think this is the old way it was described, but today, I cannot find a reference to support it.

[–] Guessologist@lemmy.world 15 points 11 months ago (1 children)

It's all about how much silica is in the lava - not much and you have basalt, fairly runny so the gas escapes and you get fire fountaining and lava flows. More silica gives you very viscous lava like rhyolite or andesite - traps the gases, far more explosive and dangerous eruption styles.

You are right
...and my use of "plutonic" is either outdated or plainly wrong.
I found this for anyone who wants to read more :
https://en.m.wikipedia.org/wiki/Lava
"Properties of lava"

Because of the role of silica in determining viscosity and because many other properties of a lava (such as its temperature) are observed to correlate with silica content, silicate lavas are divided into four chemical types based on silica content:
felsic,
intermediate,
mafic, and
ultramafic.

is that the one they were waiting for or a different one?

This is the one they were waiting for. There are several live cams trained on the area, and one of them caught the exact moment it erupted:

Thank you for the link! That was deeply satisfying to watch. The camera quality is so good.

[–] BestBouclettes@jlai.lu 2 points 11 months ago

I'd love to see that in person. It looks massive.

[–] aeki@slrpnk.net 4 points 11 months ago

Seems to be the same as it started near Grindavík, the city that was evacuated previously as a precaution.

Wake me up when it is Odin pursing some Ice Giants
