    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    Edit : My use of “plutonic” might be outdated or wrong : I think this is the old way it was described, but today, I cannot find a reference to support it.

      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        …and my use of “plutonic” is either outdated or plainly wrong.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.

      The one a few years ago that stopped flights in Europe was a basaltic one?

        The difference there was that it came up under the glacier Eyjafjallajökull and the magma meeting ice caused steam explosions throwing ash and other material high in the air.

        Oups, maybe this is an outdated terminology : I couldn’t find any references to support it. Please read my other comments and “edit” around here.

      Well, time to add Ragnarök to my Apocalypse Bingo Card.
