Where's it going? I imagine the volcano is refilling after the 2018 drawdown. And that is everywhere, not just the central summit complex but down the west side, and the east side, all over the place. So, the higher it fills in the middle the more lateral connections it fines to fill along the way.. summit rises to a level, finds a side void to fill.. over and over. and sometimes instead of finding a void it erupts for awhile.. but overall the mountain is regaining what it lost.
The following paragraph has been edited to include later observations..
But this event specifically, my sense, based on the distribution of earthquakes (at this time) looks to be an intrusion into the East Rift Zone.
As to the deep Pahala - shallow summit relationship.. this paper..
The magmatic web beneath Hawaii @ https://www.science.org/doi/10.1126/science.ade5755
is an interesting read.. with good graphics to help visualize the entire magmatic path from source to the two edifices on the surface..
Me, personally, I throw my hat in with the butterfly effect.. it's all related.. it's all hydraulics.. there's answers in there but the system is really complex.. the nuances make an empirical model hard to come by. But damn it's been an interesting lifetime contemplating it. Especially when so many advances have been made in the tools we have to monitor it with.
