Watching the earthquake swarm?

Why donʻt you go bicker on another thread. They posted useful information. You didinʻt.

Are you bickering? Please tell me what electronic tilt is. Where is MyManao's "not static" plot?

No, the tilt meter file that is available online does not update continuously. How could it, each pixel in the plot represents a measurable amount of time, and there's not enough pixels to show a "continuous" plot. And, the image I posted is the exact same image (same url of the image on HVO's site), which is updated inline here in this thread as soon and the same way the image is on the HVO site is updated. And, just like HVO's site, it's static in that at any viewing it doesn't change, but dynamic in that with a reloading of the page, if the necessary amount of time has elapsed, it will update itself. Just look at it now.. and realize it has changed considerably since I first posted it.

Edited to add: About the time value of a pixel in the file in question. The plot area in the native file posted is 750 pixels wide, and the time covered is 48 hours.. ie roughly 4 minute a pixel. So, yes, the data is being recorded continuously, but the output is limited by the resolution of the plot.

Well, that ends that bit of bickering.

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 Hawaiihttps://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.

You didn't provide a link, so we only have your posted graph.

Link to HVO Kilauea Deformation Summary page..

https://www.usgs.gov/volcanoes/kilauea/s...ta-kilauea

Showing both a few tilt, and a few GPS plots representing different points on Kilauea and at different time scales Including the one I posted inline earlier today.

And I will add.. looking at the distribution of earthquakes now (10:30pm) there seems to be an east rift intrusion in the works that has propagated maybe as far as the Mauna Ulu parking lot at the bend in the Chain of Craters Road..

Thanks for the clarification. You said what I was trying to say. :-) Quieting down a little bit since its move toward NERZ. The unfortunate metaphor that comes to mind is of the termites currently burrowing through my kitchen ceiling.

Well, before I went to bed it looked like the volcano was beginning a play to the ERZ.. and before I woke she decided to punt. The ground opened up just southwest of the summit caldera around 12:30am. There's no cameras in the area and the map below is the first data posted showing the approximate location of the initial outbreak..
