Kilauea is a separate volcano grafted onto the side of Mauna Loa and has it’s own magma supply from 60 miles below. They are not well connected as Kilauea is just piled onto the side of Mauna Loa, so the whole thing could slip free! The East and West Rifts are the result of movements as the mass of overburden accumulates. As can be seen on the sea floor this has happened before and will happen again.

Watch this simulation of the area in question!

This already started in 2000 and is getting worse. The present “New outburst” is Kilauea dumping it’s lava into the spreading crack, The “Pink” dust and red lava of the outburst was old wet decomposed volcanic rock of the crack remelting and being pushed out ahead of the new lava from the Kilauea vent lake. The people evacuated from the effected area are being moved down slope to a community on the coast! What the ####! If this moves sloooowly there would be time to evacuate. If a fast slip happens It could be BAD for everyone on the Pacific Rim. A 100ft tsunami at Long Beach.California! …pg

This Thursday, May 17, 2018, aerial image released by the U.S. Geological Survey, shows a view of ground cracks on Pohoiki Road during an overflight of the eruptive fissure area at about 7:00 a.m. HST near Pahoa, Hawaii. Cracks continued to open and widen, some with horizontal and vertical offsets, in the area during the past 24 hours. These cracks are caused by the underlying intrusion of magma into the lower East Rift Zone in the Big Island of Hawaii. (U.S. Geological Survey via AP) [bold added]
.That “slump” has created a crack or void that is filling with melt and magma from the Kilauea main vent. As soon as the voids are filled and the main vent begins to refill, it will hydraulic the crack and push or lift the top of the slump. There will be quake swarms as the slump starts to travel. This is a huge train and will take time to get it rolling. Look for increased elevation of lava fountains at the cracks as a first warning of the voids being full, the main vent beginning eruption out burst as it refills.
I would be monitoring deformation just below that fault or fracture line for both linear and elevation changes. The deformation of the road illustrates the spreading as the slip moves.
This may be a false start or might become a Pacific coast disaster of massive proportions. This could take a few days or even millennia if the magma chamber fails to refill before cooling freezes the intrusion and temporarily locks the slip. I fear the worst…

There is Geological evidence of 200 ft Tsunami Waves all up and down the Pacific Coast.
I just talked to a friend that gathers interesting information. There are psychic indications of some major disaster, financial/physical, around September.. .pg

    Saturday
    “Eruption of lava and ground cracking in the area of Leilani Estates subdivision continues. A fast-moving pahoehoe lava flow that emerged from fissure 20 this afternoon continues to flow southeast. The flow has three main lobes. The easternmost is east of Pohoiki Road and is moving about 230 yards per hour. The westernmost of the lobes is near Malamaki Road and is moving at about 40 yards per hour.
    Additional ground cracking and outbreaks of lava are possible in the area. Residents downslope of the region of fissures should heed all Count of Hawaii Civil Defense messages and warnings.

    Magma continues to be supplied to the lower East Rift Zone as indicated by the continued northwest displacement of a GPS monitoring station. Elevated earthquake activity continues, but earthquake locations have not moved farther downrift in the past couple of days.”

    latest image:

    Spattering continues from Fissures 6 and 17 with significant lava flows being erupted from Fissures 20. Two of these lava flows from Fissure 20 reached the ocean along the southeast Puna coast overnight; however, a crack opened under the east lava channel early this morning diverting the lava from the channel into underground voids. This may cause changes downslope in the channel system and the ocean entry.
    This eruption is still evolving and additional outbreaks of lava are possible. Ground deformation continues and seismicity remains elevated in the area.
    Future outbreaks could occur both uprift (southwest) and downrift (northeast) of the existing fissures, or, existing fissures can be reactivated. Communities downslope of these fissures could be at risk from lava inundation. Activity can change rapidly.
    Seismicity and deformation continue at the Kilauea summit. Deflation is ongoing. Additional earthquakes in the Kilauea summit area are expected as long as the summit continues to deflate.

    There is also some more ground movement as the fracture zone widens …pg

    Fissure 22 is erupting a short line of low lava fountains that feed a channelized flow that reaches the coast just north of MacKenzie State Park. Spattering continues from a reactivated Fissures 6 that intermittently feeds a short lava flow. Fissures 17 and 19 continue weak spattering.

    Map as of 11:00 a.m. HST, May 22. The flow field has not expanded significantly during the past day because most of erupted lava moved southward through the active lava channels and into the ocean. Note a new lava flow that was observed during this morning’s overflight west of the active channels (see label). There was a single ocean entry this morning. Shaded purple areas indicate lava flows erupted in 1840, 1955, 1960, and 2014-2015.

    Ground deformation has slowed and seismicity levels have decrease in the area. SO2 emissions have tripled, up to 15,000tons per day. So far the Trade Winds have been taking the emmissions and ash up and off shore.
    The area of Kilauea continues to deflate while Seismic levels, which abruptly decreased after the recent explosive eruptions, are again slowly increasing…pg

    Kīlauea Volcano Lower East Rift Zone

    Eruption of lava and ground cracking continues in the area of Leilani Estates and Lanipuna Gardens subdivision.

    The middle portion of the fissure system continues to produce the most robust eruptive activity in the Lower East Rift Zone. The most active fissures have been 22,19, 6, 5, and 23. A faint glow was seen from Fissure 9, but no flows, and methane was observed burning in road cracks overnight. The ocean entry remains active and is producing occasional small explosions. Observers noted the height of the perched lava pond / channel had reached 11 meters / 36 feet above the ground level.…pg

    Kilauea continues to deflate as it bleeds into the rift. As the rift expands and fills, the surface above fractures. The rift seems to have sealed east of the Puna power plant and the lava outflows from fractures are moving up stream towards Kilauea to the west. Earthquake swarms are moving from the Leilani Estates west towards the Volcano and from the Volcano east towards the Estates.
    So far, the slump is moving slowly towards the sea. The magma plume that feeds Kilauea is fairly quiet so the volcano continues to deflate as it’s magma chamber is draining into the rift. As the chamber depressurizes, the magma plume below will begin to liquefy and speed it’s accent into the chamber. This little eruption and lava outflow could be the start of something BIG! Time will tell…pg

    Things seem to be changing. During the last couple of days the amount of lava being vented is increasing, the out gassing of SO2 is increasing, and the mix of old and new magma is getting younger. One could surmise that the plume from below is moving UP ! Over 2,400 acres have been covered with new lava so far.

    from USGS – HVO may 26 report
    Fissure 22 continues to erupt lava that is flowing southeast to the coast and the lava ocean entry. Fountains at Fissures 6 and 13 feed lava into a channel that reaches the coast forming a second ocean entry.

    Fissures 7 and 21 are feeding a perched lava pond and pāhoehoe flow that has advanced northeastward covering most of the area between Kaupili and Mohala Streets. The flow front has become an ‘A’ā flow and is advancing slowly toward Pahoa Pohoiki Road. The latest observations indicate the flow front is about 150 yards from the road. On the west side of Fissure 7 a perched pāhoehoe flow (near Makamae St) broke out around 04:00am feeding short flows to the west. Overnight, flaming and vigorous spatter was observed from a cone on Fissure 8, while Fissure 17 was the source of multiple booming gas emissions. Sensors in the LERZ indicated that the lava ocean entries remained active overnight.

    Kilauea is also venting greater amounts of SO2 and ash and as it continues to deflate. a 4.5 quake happened early today along with swarms of lesser quakes…pg

    Latest USGS- HVO report

    Lower East Rift Zone, Leilani Estates and Lanipuna Gardens.
    Fissure 8 fountaining persisted throughout the night,as high as 260 feet over ground level, and the channelized flow continued to deliver lava northeast along Highway 132 to the Kapoho area. Lava is advancing along a 0.5-mile-wide front towards the ocean at Kapoho Bay between Kapoho Beach Road and Kapoho Kai Drive. As of 7:30 AM HST, the lava flow was about 430 yards from the ocean. Other branches of the Fissure 8 lava flow were inactive.
    All other fissures are inactive, although Fissure 9 is steaming heavily.

    Kilauea
    Earthquake activity at the summit was high overnight, and it is possible that a small explosion, much like those that have occurred during the past two weeks, will take place in the next day. Ash emissions are low as revealed by webcam views this morning. Volcanic gas emissions at the summit remain high.

    In the last week the numbers and size of quakes have increased and depth as decreased. Doubled in numbers over the last week along the East Rift, now the height of #8 fountain has dropped to 120 feet. My WAG is that the south side of the rift is beginning to open and fill down 4 to 2 miles.
    Imagine the volcano is a stack of bricks stacked on the side of a bigger, older stack. Kilauea is piled on the side of the much older Mauna Loa. Because the pressures of magma from below were in balance, Kilauea held a lake of lava so long that the “lake” froze over. Molten glass/magma is very erosive to solid rock and the “lake” opened a drain into the rift. At first there was a outburst of red dust and steam as the rift filled with magma. It appears that the rift was plugged about the area of the PGV site during earlier eruptions. This fill and drain of the Kilauea has happened several times before. If the reservoir of magma becomes drained and the overburden to the south does not bulge too much, things at the rift will settle down as the magma drains and cools. This is the normal outcome. Intruding water into the “leak” will clout the drain, Kilauea will go into major eruption of gas and ash. If magma continues to drain into the rift, hydrolic forces will continue to push on the “brick pile” bulge out until it fails to remain stacked. Right now earthquakes indicate that there is filling and pressure fracking of the “brick pile” down about 2 to 4 miles, and the surface fountains height is decreased as pressure is being reduced because of the bulge volume increase. The magma chamber is still draining and the area of the Volcano deflates. Newer hotter magma is still being supplied from below, and earthquake activity is still increasing.
    When the lava fountains stop get ready to run! …pg

    Numbers of quakes is about the same but the activity is moving seaward and deeper 4-5 miles. Magma flow from below has increased and the #8 fountain is over 200 feet high. Kapoho and Vacation land is covered with lava and the bay is filled. Kilauea continues to erupt gas and ash as the cauldara settles from deflation. Lots of small quakes…pg
