Kilauea Eruption 9/29/21
#9
I don't recall hearing anything about an imminent eruption as in previous episodes...

Yeah, this eruption wasn't as noisy in its onset as a bunch of breaking ground on the way to the surface would usually entail. But then, when we think of the pounding the caldera and associated magmatic structures endured back in 2018, I think it's reasonable to envision the summit as a pile of ruble contained within a vertical rock tube, verses the often thought of solid layer upon layer built up miles thick roof over a magma body safely contained within that we're used to. As such there's nothing to break, to force open, rather than just push aside. And, not much seismic noise.

I'm toying with the idea of an open chimney from depth to the surface which doesn't require a lot of built up energy to break ground. Instead, a pulse of magma comes into the system and passes, without any appreciable resistance, through to the surface..

Yeah, I know, it's simplistic, and surely there's a myriad of other forces involved.. and still, without the initial fissure eruption driven by an abundance of pent up energy I began to imagine that deep earthquake back in August near Pahala leading to the shallow seismic swarm South of Kilauea's summit a few weeks later, leading to the just started eruption as one continuous series of events. Magma rising though a broken up edifice and spewing, without much fanfare, onto its surface. Maybe not the same magma, but a batch entered the system and without any resistance its energy was transferred hydraulically to the summit and 'pushed' the magma that was closest to the surface.

I like that idea.. as if we get a spell in which all the other stuff, storage under accumulating pressure and eruption/pause cycles at vents on the flank, etc., aren't a part of the things we consider. But rather, we get a feel for how the Earth itself supplies Kilauea directly. Its waxing and waning. Its heartbeat. How much magma is in a 'batch,' are they always the same amount, or do they vary? And if so why? Things that were, until now, hidden under so many other layers, other forces. Fun.

If my vision (and yeah TomK, we know, I'm a raving maniac) is anywhere near what is happening then the amount of lava erupted will be in some way equal to the amount of magma that entered the system behind it. And, my sense, considering the scale of the events that preceded this eruption, it will end in short order. And we'll have other similar events soon as well..
