Defuse a volcano? (26)

1 Name: Anonymous Scientist : 2011-10-27 19:42 ID:Yc4D7ZOM

As this is the ever-highly speculative Science board, I put to you a highly speculative scenario: Are you a bad enough dude/construction company/government agency/super villain to stop a volcano? Can you think of a way to take enough energy out of the equation to make a volcano sputter rather than explode?

I say this with the threat of Uturuncu popping its top sometime soon and potentially messing with the weather even worse than Pinatubo did. Also, I'm all about job creation...

Don't hold back! I want to hear crazy ideas.

You could probably earn more than a million bucks by defusing volcanoes.

Someone needs to defuse the Kilauea volcano before it blows its top and kills us all!!

23 Name: Anonymous Scientist : 2018-08-20 19:05 ID:jdaHTFmh

>>22
Kilauea is a shield volcano which means it never does anything except gently burp lava. The only people it's going to kill are locals and dumb tourists, and even that's only likely if there's another pyroclastic flow like in 1790.

Ok, I'm thinking our best bet would be >>15-san's idea.

According to Wikipedia, the Altiplano-Puna Magma Body has a volume of 50,000 km^3. Our goal should to change the melt from felsic/intermediate to mafic. This requires increasing the temperature by ~300 C, and the iron composition by about 7%.

Using a density of 2.5 g/cm^3 for andesite, and a specific heat capacity of 591 J/kg*K, we get 1.25*10^17 kg of magma, containing about 9.5*10^22 J of heat energy. Increasing the temperature by 300 C would require an additional 4*10^22 J. For reference the largest nuke ever set of (Tsar Bomba), released 50,000 tons of TNT worth of energy, or about 2*10^14 J. We'll need about 200,000,000 Tsar Bombas to pull this off. I didn't look in to it too far, but there is probably enough uranium on the planet to make these bombs.

Next is the iron. Probably the easiest way to do this is to drill grid of boreholes (like >>7-san mentioned) across the Altiplano-Puna plateau, and just feed the drill steel straight into the magma. To increase the iron by 7%, we'll need 2,000 km^3 of iron, or 1.4*10^16 kg. World pig iron production was 1180 million metric tons in 2015, so we'll only need 12 years to produce that much.

In short, it is a lot more feasible than you might think. Obviously, I haven't considered the logistics of getting everything to the mountain. Also, I don't really know how we would get the nukes to the magma. More boreholes?

Some additional thoughts:

The nearest town is Antofagasta, which already has a big port due to the mining companies. Also, about half of the distance to the mountain is already covered by Ferrocarril de Antofagasta a Bolivia. We would likely have to lay ~200 km of new rail from Calama to the mountain.

Additionally, the current railway only handles about 2 million tons of freight per year, so it would need to be significantly expanded. The Daqin railway in China can transport 440 million metric tons per year, so three lines similar to that would be sufficient.

The port will need to be expanded, as well. Ningbo-Zhoushan port, also in China, supposedly the largest port in the world by tonnage, would almost be able to handle the load. I couldn't find how many berths are in Antofagasta, but we will likely need about 200.

Finally, I think that producing the uranium for the nukes will probably require the most effort. Refining an entire planet's worth of uranium is a non-trivial task. According to Wikipedia, it takes 62 SWU to produce 10 kg of low-enriched uranium. If current world enrichment capacity is 66700 SWU/yr, we will need at least 100,000 times more enrichment capacity to hit our 12 year schedule. (Someone should double check this calculation.)

Nice work. This seems like a worthwhile endeavor.

Do you think detonating 200,000 large-payload nuclear devices might have any side effects that would need to be managed?

I was thinking fallout, mainly, but I also wonder if there's a risk of the pressure waves triggering a secondary earthquake, since most volcanoes lie near fault lines.

Any ideas how to defuse an earthquake?

> 1. The aim of this report is not to question or to fight a belief – the right to freedom of belief does not permit that. The aim is to warn against certain tendencies to pass off a belief as science. It is necessary to separate belief from science. It is not a matter of antagonism. Science and belief must be able to coexist. It is not a matter of opposing belief and science, but it is necessary to prevent belief from opposing science.

Stopped reading there.

There is NO evidence of evolution. It is a belief. Objective science doesn't support evolution no matter how many frauds and hoaxes are fabricated to support evolution. The truth always trickles out.

Life doesn't just happen. That alone totally defies the Laws of Science.

The Judeo Christian G-D, made it happen. G-d is the Author of all science. It is no coincidence that leading evolutionists are atheists. THAT is by design. These atheistic evolutionists do not find G-d acceptable in their premises. Their premise is that there is NO G-D.

Please listen to me!Japan is doing terrorism with state power!
Japan is famous for sloppy management of electromagnetic wave.
Japanese society Has become serious thing behind the scenes.
Electromagnetic wave is secret globally.
But Japan can`t take a cooperative attitude In the field of electromagnetic wave use.
Because some of Japanese abusing it that state secret.
They slander Japan and Japanese people and other country(America and others), and attack and threaten people,suggest that murder,Threaten to kill,using electromagnetic wave all of them.
They are antisocial terrorists with state power.

But they feel at ease.
Cause Japanese government permit terrorism!
It seems like Japanese government don`t have the motivation to prevent terrorism!
Apparently many Japanese take part in crime and playing that abusing state secret.There is a possibility that they supporting to terrorists.
Do they have awareness that it is own country?
