You know that tragic condition that afflicts senior and distinguished members of various fields? The one where they become irresistibly compelled to make a blithering idiot of themselves by blundering into areas they know absolutely nothing about? Looks like Larry Tribe has come down with a bad case:

:roll:

Some mainland news outlets are telling scary stories about the Ring of Fire and what parts of the US are doomed. Doomed, I tell ya! To add credibility, the stories report that geologists are keeping a close eye on the volcanoes.

Cuz, duh, that's their job.

As I remember, isn't Kilauea the wrong Kind of volcano to go all Krakatoa? Now some of the other ring of fire specimens, including some of the home grown ones could be. To me it is more concerning that so me of them could get up so to speak.

Yes, Krakatoa is a very different kind of volcano from Kilauea. And Kilauea can't do anything to affect the volcanoes on the mainland.

Too, also, there's not a lot about this eruption that's different from what's been going on at Kilauea over the last 30+ years - the vast bulk of the eruptive activity that's been happening since 1982 has been coming from the rift zone, not the central vent. This is just movement of the activity farther down the rift zone - but just to another area that's seen plenty of this sort of eruptive activity in the past. The only new element is the possibility for explosive activity at the central vent, and even that's not really a new development - there was a similar episode in the 1920s.

As traumatic as the Kilauea eruption is to those directly affected, it's not showing signs (at least as of now) of doing anything special or abnormal for this volcano.

We flew over Kilauea in a helicopter when it was not terribly active in 2004. It was fascinating. We stayed at the hotel that overlooks it. I wonder how that's doing with all this activity.

It's been too many yeaars since I studied this in school, but I do remember that Hawaii's volcanoes are different than the usual variety, flowing and building, and this eruption for tthe most part seems to be pretty much in keeping with prior eruptions. I think the big difference is the much larger audence and the immediacy of it thanks to the intrnet.

Volcano House is closed, as is the entire park. :(

That got me thinking about Volcano Village! I just checked, and it's still open for visitors. https://www.lovebigisland.com/volcano-village/

I wouldn't want anyone to get hurt or killed, but I wonder if they are keeping the fireplace going.

Don't know, but it sure seems like somebody hasn't been throwing gin in the crater lately.

New fissure is seen spewing lava hundreds of feet in the air in Hawaii's Pahoa as officials warn of the possibility of an "explosive eruption." https://abcn.ws/2L1PO70

Thanks Lani, interesting. I don't know if it has changed since the late 60s, but when we lived on Oahu and bought a house, there was no owning the land - one paid rent on that. At least that's what I remember, if I'm wrong, I'll blame it on only being in grade school and based my facts on what the adults told me :oops:

No link, but I did see a headline a short bit ago that fissure #19 has sprung.

As explained to me, the earthquakes are opening up new fissures below the lava, which momentarily is sparing parts of the island. On the other hand, if these fissures continue to open further, by repeated earthquakes and the pressure of flowing lava, the lava will actually trickle - or more likely flood - down into the water table below the surface of the island. When that happens, the water will turn to steam and the resulting pressure will cause an upward explosion not merely of the hot lava but of the rock and soil and everything built on it. Conceivably this could sink the whole island. The closest analogy would be the 1883 destruction of Krakatoa, in Indonesia, which darkened the skies for hundreds of miles, spread debris even farther, and sent vibrations that could be felt in London.

Even if such drastic effects are unlikely or impossible, I think the US Navy ought to send Big Boats to help evacuate the island.

Kendra, most land neighbor islands is fee simple, unlike Oahu.

Yep, fissure 19 was born a little while ago. Also, the steaming cracks in roads are increasing. If one of them blows, mass evacuations will be underway as safe exit routes will be diminished.

Too, also, fee simple ownership is (IIRC) increasing on Oahu. A lot of the land was owned by trusts, and a lot of those trusts have hit the limits of the Rule Against Perpetuities and closed out. I believe that in quite a few of those cases, the leaseholders were given a chance to purchase the land.

#18 became #17, but now there is a newer #18. Also, a #19 and #20. Another steaming area has been located and may become our #21 by the end of the day.

And just for fun, Kilauea crater had a big boom today followed by a cloud rising an estimated 3,000 to 4,000 feet originally, but new reports say spurts to over 10,000 feet.

Looks like the eruption was around dawn. Not sure how many of the other pictures around are current vs from prior days.
