Fissure(s) 17 & 18 on the Leilani Estate are exceptional atm:


ETA Phew! That was a noisy hour - time to change batteries on the cameras and for me to get some brekky...

Indications are the lava is rising from deep ....much hotter and more liquid ....this could be a very long eruption.

Doesn't seem to be slowing down much - another live tube from Lower Puna - must be getting close (a mile-ish) to the ocean...

Very true. I listen for at least an hour with my morning brew (or few). How those guys are getting any sleep is a wonder to me.

Looks like it will track the 1955 eruption down to the sea.

before and after images of Leilani....I'm sure we would not even recognize it now

All those trees covered with lava. This is what will remain with some.

Well, you see, lava is fluid and as such, not only conforms to the shape of its container or obstacles in its path, but is also very hot, and incinerates things, including trees, birds, squirrels and humans. The heat capacity of rock-forming minerals (and magmatic solutions of them) is only a few joules per gram, and so a big enough squirrel won't be completely incinerated by a lava flow. In this case, the tree was not completely incinerated, and so there was no hole for the lava to flow into before it had transitioned from the liquid to the solid state by coming into contact with what was for the lava a very cold tree. It rains occasionally in Hawaii, and the residue of the partially-incinerated tree eventually was washed away by the rain, leaving the hole that we see today. I just thought you might like to know. In Pompeii, Campania, Italia, there are castings of human beings formed by an incandescent ash flow from the 79 CE eruption of Vesuvius.

In my home state (Washington) there is a rhinoceros cast formed in exactly the same manner as the tree cavity (Blue Lake Rhino). This specimen was probably dead before entombment. The only real difference is the rhino was encased in a flood basalt event. I remember explaing all this in great detail to Robert Beyers only to have him wave it all away with his usual inane bullshit.

Lava from a Kilauea volcano fissure flows at dawn on Hawaii's Big Island on May 19, 2018 in Kapoho, Hawaii. The U.S. Geological Survey said the volcano erupted explosively on May 17 launching a plume about 30,000 feet into the sky. (MARIO TAMA / GETTY IMAGES)


On Friday afternoon, the lava changed dramatically with one fissure ramping up and sending a flow across a road, destroying four more homes and isolating residents, some of whom had to be airlifted to safety.

The change is attributed to new magma mixing with 1955-era magma in the ground, creating hotter and more fluid flows, scientists said.

“There’s much more stuff coming out of the ground and it’s going to produce flows that move further away,” said Wendy Stovall, a U.S. Geological Survey volcanologist.

By Saturday morning, two of 22 fissures had merged, creating a wide flow advancing at rates of up to 300 yards (274 metres) per hour. Aerial footage from the USGS showed fast-moving lava advancing to the southeast. The flow was 1.5 miles (2.4 kilometres) from the ocean, scientists said.

In the background, the footage showed lava fountaining 328 feet (100 metres) high at one of the fissures. The fountains are created by vents closing, forcing magma to burst through a single outpoint, Stovall said.

Seriously hot lava burning its way to the sea.

The earthquake swarm is more concerning to me than the lava flow itself, and here’s why. These quakes are indicative of deformation in the deep bowels of the island, and probably caused by magma migration. If this migration is of a volume large enough to deform the surface morphology to such an extent as we have witnessed to date it could be a portent a much more devastating event. Enormous sections of the Hawaiian islands have sloughed off in the past, and could easily do so again. In such an event the local effects would be beyond comprehension, and could generate powerful Tsunamis capable of reaching North America. If such a slumping event exposes the magma chamber/system to inrushing sea water an explosive reaction of epic scale would follow.

I would absolutely love to talk with one of the local vulcanologist about what they think is going on, because the news media, as usual, seems only interested in the visual effects of this event.

There has been much mention of the Hilina Slump in the tube chatrooms but nothing of any consequence that I recall... :dunno:
The Hilina Slump, on the flank of the Kilauea Volcano on the southeast side of the Big Island of Hawaii, is one of several "slumps" (a form of mass wasting) that ring the island, where deposits on the side of the volcano are shifting down-slope and out onto the ocean floor. Between 1990 and 1993, Global Positioning System measurements showed a southward displacement of the south flank of Kilauea up to approximately 10 centimeters per year.[2]

Despite speculation that the Hilina Slump could catastrophically collapse and generate a Pacific-wide tsunami, the U.S. Geological Survey reports that such an event is extremely unlikely because slumps are associated with a slower type of movement that is not associated with tsunamis.

I think that is unlikely on the Big Island as the slope of the land is quite gradual ...the nature of the lava is fluid and quick moving and doesn't build to large unstable slopes as some other volcanoes .....Canary and Cape Verde are very real threats to huge North East US coast of giant tsunami and towering Rainier is as well.

It is astonishing how it towers over the coastal rockies

Compare that sharp profile to the big island

Journal of Volcanology and Geothermal Research 138 (2004) 43 – 76

Extensive landslide deposits have also been mapped around ocean island volcanoes of the
Canary and Cape Verde islands (Carracedo, 1999;
Elsworth and Day, 1999) and Re´union (Duffield et al.,
1982; de Voogd et al., 1999). Catastrophic collapse of
volcano flanks has also been documented in terrestrial
settings, such as at Mount Shasta (Crandell, 1989),
Mount Rainier (Vallance and Scott, 1997) and Mount
St. Helens (Lipman and Mullineaux, 1981).
have been a significant process.

Now that said ....nothing precludes a subsurface major slip off the Big Island that while not presenting a large local risk could indeed fire a devastating tsunami across the Pacific.
