Kilauea Eruption 12/23/24

Several businesses in Volcano display the YouTube channel below on tv for their customers.  It contains live split screen views of Kīlauea, plus ticker-crawl along the bottom.

It reminds me a bit of the 2018 eruption, ie when asked what will happen next, the scientists shrugged.

Is anybody else awake? Lots of quakes at the summit and the tiltmeter has just risen 30+ microrad over the last couple hours. That is far more than the maximum inflate/deflate pattern weʻve seen over the last few years.

No, I wasn't watching.. am just now catching up.. what a ride. A few points..

Looking at the earthquakes it's worth noting they are all shallow, within the edifice.. all registering between 1km and -1km (where 0km is sea level). And, the northern trend makes one wonder if some sorta of widening.. a new dike maybe.. north of Halemaumau (like all those other vents) is occurring? The increase in tremor suggest some sort of mass migration of magma. But it apparently did not detract from the magma present at the vents.

Interestingly, The largest quake in the series was located right in the middle of the caldera. Right in the middle of the northern side of the rim of the current crater. This is an area where we had a fissure, with an east west strike to it, eruption in 1982, just before the onset of East Rift activity at Puu Oo.

Also worth noting, a few hours later there was a surge of eruptive activity at 00:55 at the northern vent that latest about 5 minutes. This was notably gas depleted.. no spatter, no flying lava, just a gush of melt overflowing the vent.

But all told, what does this mean? It will be very interesting to see what HVO concludes. Hopefully it will be in their update this morning.

I have always expected a change from gas rich high volume episodic fountains to continuous low level eruption effusion of lava.. a lava lake.. as the most possible end of these series of fountains. But that is just because it's a traditional scenario. But no matter, it's always fun!

ETA: HVO posted in this morning's 9:05am update here..

Increased earthquake activity began yesterday, September 30, 2026, at approximately 2 p.m. HST, underneath Halemaʻumaʻu. In the past 24 hours, there were 98 shallow earthquakes located across the summit region, primarily underneath Halemaʻumaʻu, the largest of which was a magnitude (M) 3.4 earthquake at 9:52 p.m. H.S.T. Starting around 8 p.m. HST., summit tiltmeters began to show extremely rapid changes consistent with crack growth in an east-west orientation near the current vent area, suggesting that magma was intruding in this region. Most of the seismicity was confined to the western part of Halemaʻumaʻu and the northwestern part of Kaluapele, the summit caldera. Between 8 p.m. H.S.T. last night and 3 a.m. this morning, Uēkahuna tiltmeter (UWD) recorded approximately 38.5 microradians of inflation (this value has been corrected for a spike in the signal caused by the M3.4 earthquake). Since 3 a.m. H.S.T. this morning, summit inflation has flattened out and earthquake activity has decreased. A comparison of webcam imagery before and after the intrusion does not show any new ground cracking or eruption of lava in a new location.

Holei Sea Arch in Hawaii Volcanoes National Park collapsed last Sunday. The storms and waves took their toll:

Anyone keeping track will have noticed we just had another, about the same magnitude, earthquake, at the same location on the crater floor as the largest of the swarm the other day, with a corresponding bump in the tilt as seen here..



Keeping in mind the above plot is linked directly from HVO and is constantly updating so the data being discussed will move off the plot in time..

Interestingly, HVO has not repositioned any of the three publicly available cameras to focus on this area, there has been no (seemingly) change at the main vents, and the tremor hasn't changed appreciably as a result of this event.. as seen here.. showing the last 48 hours so as to see, at the time of this posting, both the initial swarm, near the top of the plot, and the new event near the bottom..



Again, Keep in mind the above plot is linked directly from HVO and is constantly updating so the data being discussed will move off the plot in time..

The YouTube feed changes all of the time.
Right now V3 is zooming in on something going on.

This all reminds me of an old ditty that begins, "Here I sit, broken hearted..."

iʻm reposting this here because I have no idea why it ended up on the Bicker Board. Who was bickering? I was responding to MMʻs informative post about the sudden changes at the summit. I even unignored Karen to try to see what was going on and I still donʻt understand. What on earth does this have to do with the Hawaiian Kingdom? It was a reference to my frustration about staying up late to wait for a dramatic eruption event that didnʻt happen. Mods, what was the problem with this?

First, what does this "ditty" have to do with Puna, Hilo or Hawaii?

Secondly, its abundantly clear you have no idea what an absolute offensive statement you made is. 

That's the even sadder part.

ETA: The ignore/unignore schtick, is really getting old.

It was a reference to my frustration about staying up late to wait for a dramatic eruption event that didnʻt happen.

I certainly understand the frustration.

I gave up waiting ever since I traded my hiking boots in for arm chairing the streaming version, especially with its ability to go back over the previous 12 hours. But I also have the built in memories of the sights, the sounds, and the smells from 20 years on the rift, doing it live. Of dawns and dusks at the rim of the caldera in the early days of the summit eruption, pre-2018 collapse. So my arm chairing has a lot of tactile memories for color.

What I have been thinking of, while this series of no starts and a lot of anticipation has been dragging on, is the poor one who just caught the bug and had figured out you don't catch the eruption unless you forgo worrying about the time of day, the weather, and just, when it starts rumbling, beat it on out to your favorite viewing position and wait for it to happen.

In the good 'ol Puu Oo days that was a ten mile track across miles and miles of barren landscape.. at least now our poor intrepid adventurer doesn't have that barrier to satisfy their itch. But still a lot of sleepless nights huddled up on the rim of the caldera can be heartbreaking.

Although, I have to admit, it will be a lot more satisfying once that latest large jog in the tilt record is off the two day plot so we can see the changes in a more nuanced view.
