I talked, separately, with two friends yesterday, one here in Volcano, and the other in Pāpaʻikou. We all agreed that current events have left us discombobulated, fuzzybrained, and/or in a sort of dreamlike state at times. Not all the time of course, but it seems that there is so much going on so different than our previous lives of quotidian responsibilities, tasks, puttering, etc., that we feel...at best, odd. I think. And weʻre not even in Keahialaka. And none of us can really imagine or know how or what those displaced, impacted, and affected are coping (or not), dealing (or not) with all of the mau mea (many things) happening.
And the winds blow and the rains fall and the sun moon stars shine in turn, and here we be.
I always hope that these will be succinct, but I guess the Potagee get plenny fo say...Today the goal is to tidy up the checklists, since it seems that Kaluapele and Halemaʻumaʻu, and the pele in and near Keahialaka are oia mau nō...same as usual. At least by the standards of the last three weeks. NOTE that Pele and her pele first appeared in this cycle in Keahialaka three weeks ago this afternoon. Seems like more than ages ago.

interesting radar image of Kaluapele and the enlargement of Halemaʻumaʻu, and sagging adjacent. And yes, there may be illusion at play, if your eyes see the features raised, rather than sunken:
SECOND
That andesite I mentioned yesterday that erupted from F17 (if in fact it is andesite) may be related to dacite drilled into in 2005 at PGV. And yes, the bit that follows may be very GEONERD, but we should still TryRead and perhaps some thing of value or interest will be garnered.

Andesite - is a fine-grained, gray to black extrusive igneous rock. It is an intermediate rock containing some minerals found in basalt and some common to rhyolite. Andesite can look very much like basalt to the unaided eye, but it is usually less dark and sometimes greenish in colour. Andesite is composed of 52 to 63%silica (SiO2). Crystals found in andesite are mainly plagioclase feldspar, pyroxene (clinopyroxene and orthopyroxene) and lesser amounts of hornblende.
Dacite - is a quartz-rich extrusive rock which is a minor constituent of many arc volcanoes. Dacite lava consists of about 63 to 68% silica (SiO2). Dacite's common minerals include plagioclase feldspar, pyroxene, and amphibole.
And following is a link to a VERY technical piece about the dacite encounter. A few sentences in there are kind of explanatory.

Regarding "When she going stop?"... Other than saying "When she stop", "Who knows?", or other noncommittal responses... hereʻs a List of Eruptions of Kīlauea after 1790. Look at East Rift ones. They all, so far in our understanding and recordkeeping, have been of relatively short duration. [[Well...Maunaulu is on the ERZ, and went for years, but itʻs high in elevation, which may or may not mean something.]] But that, of course, doesnʻt mean very much, because Kīlauea has been erupting for a few hundred thousand years, and I donʻt think reviewing 200 years of eruptive activity can tell us anything definitive about next hour, week, month... But it may be reasonable to wonder...

The daily screenshots:
ʻŌlaʻi are shown on a different Base Map, for variety, and for a little more geographic context. Note the paucity of RED. And that curious cluster with the two reds along Kulanaokuaiki, the pali ma kai of the first part of the Hilina Pali Road. Hmmmm. Wondering if that has to do with structural adjustment processes along the Koaʻe Fault System?
and Puna ma kai...MacKenzie State Recreation Area is on the coast toward the bottom:
and finally, this mornings view from the PGcam:
Headed out to Hilo... Questions and comments are always welcome. I tried to Reset a Gadget or something to auto mail Update link. Maybe itʻs now working?
as always, with aloha,
