The Black line is west rift and east rift

The Brown smudge is the present lava flows

The tan line is about the line of the overhang

The Red bites are the previous slumps

The Orange bites are the possible future slumps

Kilauea deep7/22/18 over 20 Km

Kilauea deep7/22/18 65,000ft or 20Km and deeper

Something is going on deep under Hawaii, 120,000ft below, this seems to be happening a lot at this spot. Magma moving up from deep below the island? This swarm has deep origins far below the island and sometimes they reach to the surface because of distortions being caused. This is the west end of the Kilauea rift …pg.

    This is a quick idea of what I see at Kilauea. As the quakes shake this pile of lava shingles that are piled onto the side of Mouna Loa. they crack and move. Over the last few thousands of years lava flows from the rift have built up this pile that overhangs earlier flows from the creation of the Kilauea vent. the Western end of the rift seems to be a pivot point and the Eastern end appears to have spread about 2 miles over time. The section south of the Rift is a moving block that has broken from the main island and is slowly being pushed towards the south. The present rift eruption is the result of this movement as lava fills the rift, or crack, and overflows at the east end. The width of the active rift area is about 2 miles wide at the present eruption site From the looks of older lava flows sometimes the lava fill wedge breaks free on it’s north face, this time it is the south face. Kilauea is a very recent construct …pg

    Thanks, p.g.!

    I was looking at actual photos of and comments on the most recent activity and they all focused on the lava flows with only brief mentions of seismic activity. The picture above showing the quakes + rifts + flows + slumps is a much better illustration of the situation.

    @HR; As a life long Mechanic, It is my nature to study to understand cause and effect of anything that I take an interest in. The eruption and lava flows are nice and visual but mean very little. It is the mechanics of the geology involved that is important. Form follows function, so there are surface clues as to the events underground. Surface clues indicate that the south of rift block has been moving at a 10 inch per year rate at the east end. From time to time lava “leaks” into the rift and fills it, overflows onto the surface, and after the magma reservoir is exhausted the lava cools, glues things together for a time and Kilauea refills. The weight of the full reservoir and the vibrations of quakes causes movement and reopens the rift for the next event. It appears that the up-welling of deep magma is restricted enough to prevent a real blow off but that can change as moving hot magma erodes the passages and reduced pressures increases liquidification of the magma flowing up from below.
    The breaking off of of bits of the overhang is the most likely next event. BUT! some day that whole block will break free and collapse to the ocean floor, 25,000 feet below. Every island in the chain is surrounded with these massive slumps. it is the nature of the beast…pg

    The earthquake map of Kilauea is showing an interesting quake swarm under the west end of the West Rift, last week it was around 25 miles deep, today it is at 20 miles deep. This is deep under the island, not in it. Quakes in the island or immediately under it are less then 12 miles deep. The outflow from fissure #8 on the east end of the east rift seems to have slowed and the big quakes under Kilauea have slowed as well…pg

  5. p.g.sharrow July 31, 2018 at 10:15 pm

    increasing number and magnitude of quakes in the area of the next “bite” as well as reduced lava flow out of fissure #8 may be hints of movement down about 4 miles below…pg

  6. p.g.sharrow August 6, 2018 at 9:56 pm

    Something is happening below, Kilauea has stopped deflating, earthquake activity is greatly reduced in the area, Fissure 8 has quieted and the flow from it has greatly decreased, The Puʻu ʻŌʻō plume has greatly increased, Puʻu ʻŌʻō is the vent about in the middle of the East Rift where you see the white smudge. After a series of #4 strength quakes this vent that is on the northside of the rift began venting steam and SO2, fissure #8 is on the southside of the rift. The Rift fill material is about 2 miles thick in the vicinity of Fissure #8. It appears that Kilauea is shifting gears…pg

    Hey! P.G.:

    I’m going to send you an email too, but…

    The spouse just gave the OK to run up there this weekend. I’ve got a Mr. Beer kit and a few dozen bottles to deliver to you. Please send “how to get there” and address (GPS coords optional 😉 to pub 4 ALL At-Sign AOL dot COM …

    Kilauea has nearly gone quiet, the Rift out flows of Lava have stopped, earthquakes are in the area are much reduced, The quakes along the overhand continue, specially in the area of the next bite…pg

  10. p.g.sharrow August 17, 2018 at 6:58 pm

    Kilauea is quiet, only a few quakes per day. The lava outflow has stopped from the East Rift, but there is a quake swarm going on about 20 miles down. This is at the west end under the Kilauea rift, far too deep to be in the island. When I first noticed it, it was around 25 mile deep. Maybe the next pulse from Pele’s hot heart…pg

  11. p.g.sharrow September 2, 2018 at 2:57 pm

    For those that might be interested, the quakes in Kilauea have changed as the eruption in the Rift has ended and the numbers of quakes there greatly decreased. .
    There are now quakes more wide spread throughout the Island both in area and depth, like the whole island is beginning to flex…pg

  12. H.R. September 5, 2018 at 5:18 am

    Eventually, Kilauea is going to slough off its buildup. The only question is, when will it happen?

    Massive geological traumatic events happen on geological time scales. Humans have such short lifespans that any one given person is lucky to be able to witness a geological ‘Big One.’

  13. p.g.sharrow September 5, 2018 at 6:25 am

    It appears to me that Kilauea is a buildup on the top of a slump off of the side of Mauna Loa so the whole thing sits on a unstable foundation and the surface Rift does not correspond to the rift below. So far, the near surface quakes seem to indicate most of the instabilities seem to be at the overhang along the south coast.
    Geological time is generally very slow. At the Big Island we get to see it happening at high speed! hundreds of years instead of millions! ;-)…pg

  14. p.g.sharrow September 7, 2018 at 6:00 am

    Over the last week Kilauea has begun to reinflate, Gas emissions are increasing, and lava has reappeared in the fissure 8 cone. Earthquake numbers are slowly increasing. Many very deep and widespread under the Island.

    “God is bowling in heaven” yup. sometimes he is really on a roll…pg

    Looked at Kilauea quake map today,
    No lava flows evident and quakes down to about 10 per day. many very deep, 20+miles, wide spread and far under the Island not within it, A swarm that was under the west end of the West Rift is moving towards the East and the Kilauea Vent I would say that a bubble of magma deep under the island is moving toward the area of the vent.
    Have a WAG that we are about 3 weeks from a major event …pg

    I wouldn’t have any sort of guess as to the timing, but something has to move into the void created by the last eruption.

    The last eruption was like a singer clearing her throat, then she’s ready to go for the C above high C.

    As kids, before crossing the street, we used to say, “C sharp or B flat.”

  18. p.g.sharrow September 28, 2018 at 7:32 am

    @HR; yes the reduction in pressure in the Kilauea vent by draining a thousand feet of liquid rock has got to cause an imbalance in the plumbing below the Island. Pressure reduction causes liquidification of once solid hot rock as it moves towards the “low pressure area” . This is also like pulling the cork on a bottle of Champagne as the pressure drop releases pent up gasses, and THERE SHE BLOWS ! A real eruption ! That swarm has moved half the distance to the Kilauea vent over the last 2 weeks and is accelerating it’s movement east but not changing it’s depth, about 20 miles under the Island…pg.

    Be sharp or be flat is a good idea while crossing a street or you will wind up “flatter then a stompt on toad frog!” 😉 …pg

    Not sure you if caught that “C sharp or B flat” was a pun based on musical notes, p.g.

    nearly all activity has stopped in the eastern half of the East Rift. “In the ERZ, tiltmeters near Puʻu ʻŌʻō (see the white smudge in the middle of the rift) and farther east continue to record an inflationary trend, consistent with refilling of the middle East Rift Zone” Kilauea reinflates from deep below. The seamount Loihi, 20 miles off the south coast is the site of increased quake activity. It would appear that Pele is readying her next act…pg
