This is what is causing the eruptions in Puna Hawaii.
When it collapsed it all went into the East Rift underground system, and now is boiling up to the surface.
The source that has been going thru Puu oo is now running down the East Rift.
It collapses at about 16 seconds, pretty amazing , that crater is at least 1/2 a mile across.
And if the drain plugs up, perhaps Puu oo will get filled up again.

That video is from 2011.
Are new distal vents formed regularly as a result of floor collapses, which are fairly common?

Thank you for informing me about this clip. I thought it was a recent one.
I see what you are saying how collapses like that could spew out into cinder cones.
What I am wondering about is the larger underground system that has suddenly changed the flow from Puu oo to the East Rift.
There was a collapse.
You sound like someone who studies these things.
I would be grateful for your input.
We have been getting some pretty big earth quakes over here.
We had a 5.4 and a 6.9 , and three 4.7 's and a 4.9.. and that was just in one half hour.
There were also about ten smaller quakes that kept the windows shaking in between those.
Just from history I think this will be at least a few weeks or perhaps a month's long eruption.
It is a cool video.

I'm a geologist but don't have any particular experience in volcanology, other that what I learned in igneous petrology a few decades ago.
The crater floor collapse at PuuOo is likely part of the same magmatic swelling event that is the cause of the earthquakes and new venting in the eastern rift zone. I don't think the crater floor collapse is the direct cause of the new vents. It is a good bet it will go on for a while. I hope I get to see it in a couple months, despite my worrisome wife making other suggestions about destinations.

Anyone ever hiked through old lava tubes on the Big Island? They're awesome.

hey there, say, john...
oh my... i always (off and on) wonder about this and hawaii...
(since i was a kid and learned about some of this, in school)...
as to this quote of yours:

woww, and oh my... :O
say, PLEASE, CHECK IN, too... and let us know, later, how it goes...
(i know if anything really dangerous happens, the news will share, too, but--
we'd like to know how you are...
thank you...
say, i just saw this:
it was a follow-up, after the link that you shared... wow,
watching it now:

Good Question...

Plenty of times.
And as a kid we use to walk right down in the Kilauea crater and along the Halema'uma'u Crater on backpacking trips too.
This was 69-72.
Young boys exploring the wilds of Hawaii-good times.
Sure like to go back some day though I doubt I'll ever be able to get in as close again to that crater.

Having Lived on Hawaii Island for 25 years, I saw quite a few eruptions Close Up! Thanks again to Ed Hartouni for scanning the ones that I am posting here.
Hi John! Coming to the Bridwell Memorial? You can stay with us if you can make it here!
OK, some pix:
On this night the fountaining on the left was going about 1200' high; the vent on the right was doing what is called "Strombolian explosions" from which I could feel the shock waves from a quarter mile away.
Occasionally, large chunks of solidified lava floated down the "river," but the lava is about 2000 degrees F.
Keep safe everyone, but enjoy it if you can!

Just watching the normal slow oozing of lava from Kilauea was one of the most impressive natural phenomenon I've ever experienced, along with the many typhoons I lived through in Okinawa. I can't imagine how much more spectacular now that it's actively erupting.
When I was there, we walked for miles across lava fields that were still warm and as we got closer to the flow, we could look down holes in the crusted lava and see red hot molten lava flowing still. Closer to the ocean, it was oozing black fudge out on the beach and eventually into the ocean amid great clouds of steam. We saw several feet of new land created on the Big Island that night - all under a full moon.
Amazingly, the National Park rangers did nothing to stop the sizeable crowd from hiking in to the flow and staying there all night.

A friend of mine used to be a house sitter out there in Puna not far from the active flows so I'd visit every year.

Yup- spent a whole day hiking through one one time. They get creepier and sometimes more unstable the deeper in you go.

One thing I've observed about Hawaiian island culture- there is virtually no sense of urgency or concern for dictating or enforcing "safety" to others. You can hike out on the lava or dive into a totally sketchy lava tube without fear of "the man" telling you not to. I'm guessing liability lawsuits don't make it past the judge's mid day nap.

BooDawg, your pics are spectacular!
I lived right on the edge of the Kilauea Caldera in 1995 (in the ranger cabins- a stone's throw from the Volcano House), used to walk down to the KMC (Kilauea Military Camp) for entertainment... during a very boring and inactive time in terms of lava flows or active behavior. Walked across the caldera, explored lava tubes, participated in a wedding next to the Thurston Tubes, backpacked across the hardened flows down to the beach on the south shore. We couldn't see jack of fresh lava- it was all pouring out underwater into the sea. But it was still a wonderful experience having that be our base camp, and spending most of the time mist netting birds on the rainforest slopes of Mauna Kea.
Would be cool/scary to be there now!

There is a spot off the coast of Mal Pais, Costa Rica where tgere is an active underwater volcano or vent, not sure, probably 100 feet down. There are bubbles coming to the surface and the water is warmer around it. I dove off the boat straight down above it, maybe 15-20 feet down. Trippy, eerie feeling. Also awesome.

This is a live feed from the fissures in and around Leilani estates.
Not sure how long it will be up.
This is the first time I have seen a pahoehoe flow where the lava is way more liquid and moves much faster. You can see it in the fore ground like a river. That is a lot of lava that will cover a lot of ground.
And perhaps cutoff the main road along the coast.
They had predicted that this might happen.

Meh, once you've seen one volcano eruption, it all looks less interesting. Wake me up when Yellowstone goes.
Great photos Boodawg!

They had that huge 25" rainstorm just before all this happened. I wondered if some of that water went down to the wrong place and created an explosion that started all of this.

The big rainstorm was on Kauai,, over 300 miles from where the eruption is happening.
