April fools aside, is anyone else feeling vibratio

[dobanion]

Think 1960. Lots of similarities, so far.

[missydog1]

I hunted up some archived articles from Volcano Watch that talk about the lower rift zone eruptions of 1955 and 1960, and some related issues. Fascinating stuff, highly recommend reading it if you live near the east rift zone.

Good news for lower Puna rift zone would seem to be that the quakes are centered elsewhere, for now ... Volcano and Kalapana. There is a paragraph I quoted below, from a Nov. 2000 article, that says Currently a barrier blocks the east rift zone near Pu`u `O`o and keeps magma from moving into lower Puna.. Does that mean a barrier above the ground or below? The article is about magma travel in the system, not surface lava.

What will happen when the eruption ends? (Nov 2000)

quote:

---

The Mauna Ulu events show that, if the volcano remains pressurized, eruptions can take place during and soon after a long-lived eruption. And, the eruptions can be at the summit, anywhere in the rift zones, or both. Currently a barrier blocks the east rift zone near Pu`u `O`o and keeps magma from moving into lower Puna. How long this barrier will last, and how it will respond to the end of the Pu`u `O`o eruption, are anybody's guesses.

When we first moved here, I felt occasional vibrations that felt just like mini quakes in SF Bay Area. It wasn't until like my 20th load of laundry I realized it was the spin cycle in the washer!! (you can really feel it on post-and-pier!)

[missydog1]

DT, a good-sized mini quake here just a minute ago!
I'm washing a comforter...

Seriously, after reading the articles I linked last night, I was left feeling that the current deflation and semi-collapse of the main vents could very well mean that magma has moved somewhere else along the rift. Seems like a similar pattern to earlier eruptions.

No one knows what is meant by magma is blocked from entering lower Puna?

It's referring to a blockage in the underground plumbing. Right now Puu Oo is the path of least resistance; if the eruption completely stops for a year or more, it could develop another plug there and later pressure in the plumbing could result in new cracking that allows the magma to bypass the blockage.

And yes, P&P houses + hollow ground with lots of lava tubes means everything gets felt a lot! I'm in Hawaiian Acres near the highway and I felt several of the Kalapana earthquakes pretty strongly. The thing is, most of the time it's hard to distinguish actual small earthquakes because cars passing by on the road also make the house shake!

[missydog1]

Thank you for that explanation, Midnight Rambler. So then the actual plumbing where the magma comes from deep in the earth is high up on Kilauea? And to get to Lower Puna, the magma needs a clear pipeline? That's the picture I'm getting.

Obviously magma can exert enough pressure to create quakes and shift blockages, but let's hope it doesn't.

One end of my house is about six feet up on post and pier, while the other end begins on slab, so I am aware all the time of how much more the P&P shakes. Mine is on deep soil, which shakes more than rock. A small quake near Pu'u O'o and I feel it quite strongly, even on the slopes of Mauna Kea.

Like you guys, it's when I'm in bed that I feel the movement. Quite often I think it's a quake starting and it turns out not to be. It's interesting to hear about these vibrations, because I'm understanding now that there are vibrations from the volcano that are well beneath the threshhold of what I consider a quake, which we all pick up on.

[Frankie says relax]

Sorry, I was away for a coupla days after posting. Felt some good vibrations again overnight Saturday. And these vibrations are different from the small EQs we get...I can only feel this when I'm lying in my bed. And it's not a sudden motion, it's something like a washboard dragging over something, if that makes any sense.

As to a coupla the other questions, when scientists talked about magma being blocked from entering lower Puna and when they reference the volcanos' plumbing, they were talking about the natural occurrences and natural barriers being created underground; they're speaking figuratively, not literally. The tube systems may get plugged internally and break suddenly, just like what we see happening down at the coast when a pretty sizeable bench builds up and then suddenly breaks off into the ocean, sometimes with great explosions, etc.

During the mid1980s, like 87, 88 and 89, prior to the flows that finally took out Kalapana, the lava had flowed to the south, building up a ridge along the national park side of the flow field that was so active during those years. Then there was a break in the eruption and when the lava flows resumed, they flowed to the east side of that naturally-built ridge and over time covered Kalapana.

The scientists don't know exactly where or when these natural events are going to take place but the technology and monitoring is getting better all the time. For example take the infrared imaging HVO's been sharing with us in the past year or so. I'd love to see a long shot of a sizeable portion of the East Rift Zone done in infrared but not knowing the limits of such technology, it may not show much of anything. But wouldn't that be a great tool!

Thanks, everyone, for your responses. I really appreciate punaticbychoice's comment about staying alert and observant. May you all have nothing but good vibrations! [8D]

Kathy thank you for listing all the links! Great reading so interesting.

It would be interesting to know if underwater sea mount Lo'ihi is growing. The page hasn't been updated by HVO in quite a while but is linked here for some images fascinating really

I think when we are lying in the quiet our body gets quiet and our senses are heightened. You are perhaps feeling the gurgling of lava.


PS. I thought she died on May 21 during the rapture, no ill wishes! Maybe it was the wrong thread John.
