There is now a workshop for Mauna Loa eruption readiness. When it erupts, does it ever flow to Puna?

Sure, along the Highway 11 corridor down through Mountain View & Keaau, although it's been awhile since those paths have been traveled.

There is some speculation that the next Mauna Loa East Rift Zone eruption may send lava flows to the south of the rift's ridge. As such, if this were to happen they would impact the Volcano Farm Lots (note that the farm lots are on Mauna Loa - not Kilauea as is the rest of the Volcano community - but still in the Puna district). A longer lived flow would then go towards Glenwood and could cross over onto Kilauea there.

The speculation is based on the fact that there have been several eruptions all in the same area around the 9000 foot elevation (near Red Hill) and that the opening of each eruption, in succession, has been 100 meters or so further to the south, and that another 100 meter jog south from the 1984 vents would put the opening south of the topographic high of the rift itself.

Pure speculation, but done by a volcanologist who has spent most of his life studying Mauna Loa..

Here is a link to a map of some of the lava flows.None in Puna in historic times :

It is a presentation for Volcano Awareness Month...not because something has changed in its status.

It would be nice if you could name the volcanologist who did the research and cite the paper/s you are referring to. That's what people normally do when they refer to such a study.

I'm curious, what about "pure speculation" suggests a publication to cite?

...

Let me suggest a more expansive, free range, verbal not written source, as an alternative original statement:
"Pure speculation," but done by a "volcanologist" who has spent most of his life "studying" Mauna Loa.

Oh, I don't know, I assumed you were quoting something from a real volcanologist with actual research qualifications in the subject including a publication record. So who is this volcanologist?

Real volcanologist or pretend volcanologist? Someone with a relevant degree?
Speculation is fine, claiming credentials is dubious.

I'd go further. Claiming professional credientials you don't have is fraudulent.

One would be amazed at all the ideas passed around over dinner, at a picnic, in the library, talking in the hall, or maybe it was that time we ran into each other in KTA's parking lot? God, you'd be amazed at how often we run into each other in the KTA parking lot, especially since he moved to Hilo. Or was it at the beach? Regardless where, it's an observation one would make off handedly, 'hey did you notice that..'

I think it's an interesting idea.. that maybe the way the flank opens up repeatedly in an area has some rhyme, some pattern to it. So I shared it.. simple. I don't think it's important that I share who passed that idea on to me. But hey, let's be honest, your interest lies elsewhere. Otherwise your questions would be more to the veracity of the information.. pull out a map, check what is said. Have you done that?

Those casually shared ideas are often pretty interesting. And, over the years I have watched as many of them have percolated into research, and often publication. Whereas others just remain casual observations but are none-the-less interesting.. at least to me. Here's one I have always enjoyed batting around. Of course you can poke all sorts of holes in it, or conversely you can take the opportunity to continue your attack on me..

Have you ever noticed that Mauna Loa's East Rift Zone stops at or around that 9,000' area and wondered why? Why when all the other major radial rifts on the mountains tend to go way further, into the submarine extensions of the volcanoes? One researcher has proposed a very different model than any I have seen to date as to why that is...

He/she proposed that during the catastrophic collapse of Mauna Loa's southern flank that in some models preceded, and lead to, the onset of what became Kilauea, not only did the southern flank subside but that the lower extension of the east rift was also included in the land movement. And, that with the entire block sliding down, and to the south, what was then the east rift of Mauna Loa slid south enough to be positioned so as to be cockroached By Kilauea as she evolved, and as such everything east of Pauahi is built upon the older Mauna Loa structure.

Wild idea, eh? And one, I think, I first heard in a hot tub while discussing a manuscript we were working on together for a comparison analysis of shield volcanoes and the more popular stratovolcanoes around the world. Of course I throw that tidbit in so as to give you plenty to be obsessed with other than the actual idea itself, if that's what you really what to do. I mean, yeah, wild idea, but OMG in a hot tub? An unnamed source? Though I did hint at it being one of my co-authors, still... fire away.

But can you imagine.. that a part of the island collapsed and that the subsequent building of Kilauea included such a unique feature as being able to reoccupy an abandoned rift? Fun idea.. yeah? Though I haven't seen it in any peer reviewed publication there are other's that started out as "pure speculation," ideas batted around over beers in Reggie's office on a Friday after work, that have since made their way into the mainstream modeling now employed. But hey, one per post ;)

You should stream a podcast from your hot tub. Then we can be the first to hear all the ideas which might find "their way into the mainstream modeling" at some point in the future. Why should we wait until the information is studied, the information verified, confirmed by colleagues in the field, and finally published in a scientific journal, when it's available in 104 degree water right now?

Everyone knows 103 degree water is the best temperature to mansplain whilst simultaneously humblebrag.

I am interested in the veracity of the information, and the first step in that process is to know where the information comes from. All I know so far is it comes from you. Essentially, your whole post is a logical fallacy; an argument from authority.

Oh my, the world must frustrate the crap out of you. Sorry to disappoint, but hey, I had a conversation with someone 20 years ago and they shared an idea. And here we are all these years later and I shared it. It's just an idea.. and would be interesting to see if it pans out.. but certainly not one that's going to change anything. A teeny weeny little idea. But no.. you got up on that horse of yours and wham.. I am mud for not having a frickin' blah blah blah.

You are just so silly! But hey, carry on.. if nothing else you are entertaining.
