 Fissure 10 (green triangle) is new this morning, the steady march southwest continues. The green/yellow diagonal zone is "if you had a house here you now have scabby black rock instead". Really poo poo situation for everyone involved. The thing is as well, there's not really any way of telling how long this is going to go for. It's not like a hurricane or flood where it happens, then you can get back in and clean up. It starts happening, everyone gets evacuated, then you just get to watch as The Oh and while we're at it, there's an island in Vanuatu with a population of ~10,000 that is considering a total, permanent evacuation. Volcanic ash is killing their crops and poisoning their water supply. Edit: here's a new twist on the Leilani Estates eruptions I wasn't aware of until just now. There's a continuous deformation of the area south of the East Rift Zone called the Hilina Slump. A 20,000km³ section of the southern flank of the Kilauea Volcano that is slowly displacing to the south at about 10cm/year. This means it's a little loose in there. This means that continued uplift from the rising magma, combined with the seismic events associated with this new eruption could drop the whole thing into the Pacific Ocean in under a minute. This is an absolute worst-case doomsday scenario, but we could be talking a wave more than 500m tall being blasted out faster than the speed of sound at the west coast of North and South America. ~5 hours travel time to LA and Baja California, ~10 to Central America (where it wouldn't be too bad on account of striking obliquely), 11-12 to hit Colombia and Ecuador, where it would gently caress poo poo up. The probable angle of an event like this would mean that it probably wouldn't hit further north than San Francisco, and by the time it hit Chile it probably would have dissipated enough to only cause localised damage to boats and foreshore areas. LA, San Diego, Baja California, Colombia and Ecuador would catch it the worst. Memento fucked around with this message at 01:34 on May 7, 2018 |

Quite a bummer if you built a house there betting that it wouldn't happen in your lifetime.Memento posted:Oh and while we're at it, there's an island in Vanuatu with a population of ~10,000 that is considering a total, permanent evacuation. Volcanic ash is killing their crops and poisoning their water supply. The total population of Vanuatu in 2016 was 270,000. 10k is a considerable portion of their population to have to relocate. Looks like a pretty awesome place to retire (well, except for volcano death island).

Is there any way they can safely trigger a smaller scale collapse? Similar to how you trigger avalanches in the mountains, perhaps?

Bunni-kat posted:Is there any way they can safely trigger a smaller scale collapse? Similar to how you trigger avalanches in the mountains, perhaps? The thing with avalanches is that you're just taking off a layer on the surface. With the Hilina Slump, you'd actually be detaching a significant portion of the mountain, that has its biggest weak point at the interface between the new volcanic sediments and the older basement rock (which is also volcanic sediments, just a lot older). It would probably all fall off at once because it's essentially one large piece. The last time this happened was 1975, when a 7.4-magnitude quake caused the Slump to move a bit under 4 meters, and caused a tsunami that was detected as far away as Alaska. I just skimmed a few papers about it and it looks like there are submarine buildups that are buttressing the potential slump area somewhat, increasing the energy needed to get it to start moving. So again, this is very unlikely to happen, an absolute doomsday scenario. But that's what this thread is for!

The problem is that the lava wants out and is succeeding. You really don’t want to help it along. Hawai‘i is a weak spot in Earth’s crust. Anything you could try to do to release the pressure would just make it weaker.

This is a thought experiment I came up with* to run with some 2nd year geoscience students who had just had a semester of igneous petrology and volcanism. "Why can't we drill into the side of a volcano to let the pressure out so that instead of a catastrophic eruption, we get a controlled release of pressure?" The answer I wanted them to come with was "because releasing the pressure on a magma chamber is like opening a bottle of fizzy drink that has been shaken up - when you release the pressure, all of the volatiles exsolve out at once and instead of an eruption, you get an explosion". It's what caused Mount St. Helens to blow its top like it did - there was an inflation of the magma chamber that caused half a hillside to fall off, and once that happened there wasn't enough confining pressure to keep the volatile gases dissolved in the magma so they all boiled out at once. *I'm sure I'm not the only one to come up with it

tangy yet delightful posted:So did they come up with the correct answer or are they drilling into a volcano right now under false pretenses? I've run it twice. The first lot I ran it with came up with the answer pretty quickly, the second lot were convinced they could pattern-drill a mountainside to direct lava flows out to the ocean on my theoretical volcano - it had an ocean on one side and a city on the other. I told them at the end of it that they caused an explosive eruption that wiped out their research party and caused thousands of deaths in the city. It was also a good lesson in making sure everyone gets their say in a collaborative scientific effort, because after I told them how badly they had messed up one kid yelled out "I told you idiots you were doomed!". Bunni-kat posted:My geology knowledge is lacking, I didn’t realize there were significant dissolved gasses in magma. A lot of it is water but there's carbon dioxide, sulphur dioxide, hydrogen sulphide, hydrogen halides (strong acids) all found to varying concentrations in magma. Fun fact about hydrogen sulphide: you can smell it at like 100 parts per billion as a strong rotten egg smell. At around 10 parts per million, it becomes so strong that it anesthetises your sense of smell. So if you smell vile rotten egg smell, and then all of a sudden it goes away, you should also go away to someplace far away. Memento fucked around with this message at 03:59 on May 7, 2018 |

its usually a more than 10 ppm that h2s starta to gently caress with your senses, the assessed idlh concentration is 100ppm because thats when its supposed to kill your nose but it does all sorts of bad things at lower exposures depending on duration. cool thing about it is even if you survive a high dose dropping you instantly unconscious somehow your blood pressure will be hosed for the rest of your life, ditto for long term low doses.

"Why can't we drill into the side of a volcano to let the pressure out so that instead of a catastrophic eruption, we get a controlled release of pressure?" Use a valve to release the pressure slowly. Done. Material selection and construction process is an engineering issue and thus beyond the scope of this paper.

I thought the idea was to release the pressure BEFORE it rises to dangerous levels.

Karate Bastard posted:Do you hear something buzzing? A friend and myself were cutting up a huge, fallen, Beech tree with a massive 2 cylinder chainsaw that had handlebars on the tip side for the second guy. I think the bar length was 72 inches or something. Anyway, I was the guy on the handlebars, and as we cut down through the trunk, I began to get spattered with what I thought was chain oil, so I yelled to the guy running the engine side to cool it on the oil trigger. When we cut through the section, the tree was hollow, and inside there was a huge bee hive. I mean, combs of honey nearly 5 feet long. What I thought was chain oil was actually honey. It was cold that day, so the bees would fly out away from the hive for about 5 feet and then just drop. Yep, I did take a couple of the combs home with me, and yep, it was great honey -- as long as you could get past the bee parts in it.
