Back from the vitual sunny shore of Maniniʻōwali, to the chill wintry rains and breezes of Keaʻau ma uka... Iʻm always intrigued as to how thoughts pop into my head. Synapses connect (if weʻre lucky) and off we go. "O ka piʻo ana mai, o ke ānuenue" is a line in Kōʻula (Manowaiopuna). The rainbow arches above...
Kōʻula, or Mano[a]waiopuna is a favorite, ʻono song. I delighted when were were taught the hula by Kumu Nalani. Her voice and choreography always inspire! As with many things, there are versions, renditions, and differences of opinion based on tradition. I hear George Helm singing, and it doesnʻt match the huapala.org lyrics. So? Lovely all...
Manowaiopuna: George Helm
Certain lines of certain mele (songs) stick. Even after decades. No can help. And Iʻm grateful that they do, because those times were lovely. Iʻm hoping that links to mea internet work. If they donʻt, please let me know...
The weathers up here have brought chill rain and wind, but also a bounty of ānuenue: bright, dim, flashy full arcs, wisps of tantalizing color. Two consecutive days, same webcam, same time...same obsession with wonderinglooking.
Because of the hazards, and there ARE hazards, Iʻm evergrateful for HVO webcams, and for the photography of HVO Staff. Their eyes (and camera skills) allow all of us insight into the sublime, awe-inspiring phenomena that are the works of Pelehonuamea, as well as other elementals such as Lono whose kuleana is rain. Wow.
Please note: Previous Updates noted positive correlations between effusion rates (volumes of pele erupted), and Inflationary Tilt, and RSAM (Real-time Seismic Amplitude Measurement) activity, or earthquakes. I had to look up RSAM...
The month-long Tilt graph below, with its hills and valleys, illustrates what have been termed D-I Events (Deflation - Inflation).
Kinda complicated sounding (or not)... below, a summary of researches, published in 2015.
Because itʻs impossible to LookInside at what Pele is doing, we theorize, model, and try to make sense of what instruments tell us. Other papers describe mixing of gas-rich and gas-poor magma not far below the surface. Pele is moving around and breathing. Sheʻs not content to simply sit there. Iʻll let you TryImagine.
The three photos following are on the HVO website.
First on January 26, 2021, by MZoeller, through a laser rangefinder...looks very old-timey and hand-tinted. The erupting West Vent cone, about 130 feet tall is pictured.
The two that follow were both taken on January 28, 2021.
A closeup of the papa, the floor of Halemaʻumaʻu; the surface of the loko ahi, by NDeligne. The eastern, right-hand half of the lake is darker and slightly cooler and slightly older, and about 13 feet lower than the west side. The two sides are separated by a big crack seeming to lead to the former almost buried North Vent at the edge. We can view moku paʻa (firmly fixed islands) and the fresh silvery very hot skin, and the cooler, a bit older darker crust.
Below, by MPatrick, a wow....
No wonder we shiver...a blanket of hau (Snow. Same word as the plant with yellow flowers and good bark fibers) on Maunaloa, and though I canʻt make it out, pele flowing into the loko ahi (Lit., lake fiery, or lava lake). On the block a (big) step down from the photographer, the slightly diagonal line of what used to be Crater Rim Drive.
We can see that weʻve got awhile to go before if when maybe perhaps loko ahi overflows onto ledges of previous floors. Donʻt get excited.
Some Math: On December 20, 2021, at the time of Hoʻopuka Pele, her appearance, Halemaʻumaʻu was 929 feet deep as measured to its old rim. As of this morning, the loko ahi is 692 feet deep, with 237 feet to "overflow". Itʻs gotten 39 feet deeper in the last two weeks, or 2.8 feet per day. if If IF that rate continues weʻre looking at 84 days to overflow of Halemaʻumaʻu, onto kaulu (ledges) that are previous
sections of caldera floor. But... Halemaʻumaʻu widens toward the rim, and who knows what effusion rates (eruptive volume) will be.
Only time will tell. She going do what she going do...
As always, with aloha,
BobbyC
