Kilauea quake map 7/19/18

Kilauea quakes 7-19-2018

Kilauea quakes 7-19-2018

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

Map links,

these will open new tabs to latest maps   earthquakes map    Daily status report  lava flow maps

I use the week earthquake map, and the 5km&10km depth categories…pg


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

    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

    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 …

    @ EMSmith;replied to Email with phone numbers and then directions.
    Best bet is to meet in Chico Saturday if you are traveling Saturday.
    I go to bed after 11:00 pm…pg

    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
