So about an hour ago, Yahoo News announced a funny discovery in Ethiopia.
A bubble of magma exceeding 500 square kilometers is resting down there, deep in the earth's mantle, and it's partly connected to the dormant Badi volcano.

The article says that magma normally rests right beneath the surface where many of these rifts are concerned. But many of us readers know from studying instances of anomalous volcanic activity in Africa, such as the phenomena at Lakes Monoun and Nyos, that a very different outcome is possible, given the right conditions.

Lake Nyos has volcanic activity happening deep down, far under the water. The lake itself is quite unusually deep. What ends up happening under these tremendous pressures is a large building up gases such as carbon dioxide and possibly methane, hypersaturation of the deeper layers of water with tiny bubbles of gas. Every once in a while, the faults there will produce a tremor, or something under too much pressure may explode upward into the lake. These vibrations cause the bubbles in the lake to coalesce into giant bubbles that rocket toward the surface in an unexpected fountain of choking gases. This phenomenon has been known to kill entire villages and smother all the livestock surrounding them.

Now, why am I talking about gas bubbles in the context of volcanic deposits? Why would I draw a parallel between a relatively small body of water in African and the Afar Rift in Ethiopia? Because on the macro level, the concept may well prove to be the same. Because there is a lack of normal venting, a possibly unheard-of pressure building up deep within the mantle under Afar, the conditions may be ripe for an eventual Verneshot.

Now: what on earth IS a Verneshot? Well, most of you know that back in the late 1800s, just before Tesla started his work, an author named Jules Verne was writing some of the most moving and realistic novels thus far known to our culture. We later dubbed his form of writing "science fiction". However, some people may be unaware that Verne was the author of many working scientific theories that do not fall under the heading of fiction, but often fact.

Jules Verne proposed that every once in a while, so much pressure may build up beneath a crustal plate that eventually, the entire plate is fractured right through, or even worse, launched into orbit around our own planet. Thus, our planet Earth is capable of generating a projectile with sufficient force to temporarily leave the atmosphere and then come hurtling back down to earth!

Many scientists believe that objects like meteors, comets, asteroids are responsible for mass extinctions and the existence of craters on the surface of our planet. Jules Verne believed that a better explanation involved a terrestrial source for these objects -- objects capable of delivering lethal force to entire populations; maybe even enough to wipe out entire species.

I wanted to share this information with you guys since you are among those who tend to think and to prepare. This could happen within our lifetimes, or may never happen at all. It might not even be worth fretting about. However, if there is a chance that such an anomalous finding is capable of generating a disaster on this scale, someone should talk about it in that context at least once.

I don't want to be a Negative Nancy or a Jovian Janet -- but I do enjoy being right and would appreciate knowing whether this is possible, even long after I am physically gone.

What do you guys think about the possibility of earth generating its own projectiles, cratons that are later chalked up to "foreign objects" entering our planet's atmosphere? Is it a scary thought or an interesting thought?

After all, some writers have said, it takes some danger to stimulate growth and development in a species such as ours.

What's a Verneshot?


Verneshot
From Wikipedia, the free encyclopedia

A verneshot (named after French author Jules Verne) is a hypothetical volcanic eruption event caused by the buildup of gas deep underneath a craton. Such an event may be forceful enough to launch an extreme amount of material from the crust and mantle into a sub-orbital trajectory.

Why talk about it today?


But a look deep beneath the Afar Rift reveals the birth announcements may be premature. "It's not as close to fully formed seafloor spreading as we thought," said Kathy Whaler, a geophysicist at the University of Edinburgh in Scotland.

Whaler and her colleagues have spotted 120 cubic miles (500 cubic kilometers) of magma sitting in the mantle under the Afar Rift. Hot liquids like magma like to rise, so the discovery is a conundrum.

"We didn't expect this, because magma wants to pop up like a cork in water; it's too buoyant compared to the surrounding medium in the mantle," Whaler told LiveScience's OurAmazingPlanet.

Models predict that at spreading ridges, magma should sit just under the rifts, in the crust. That's what geoscientists see in the oceans, at places like the Mid-Atlantic Ridge and the Juan de Fuca Ridge. But not only is the giant pool at Afar extremely deep, but it is also mostly below the sleeping Badi volcano, many miles west of the scene of a 2005 series of underground magma intrusions, Whaler said.

"You just wouldn't expect to have a blob of magma still underneath this other area," Whaler said. "It's one of the things we're still having a lot of discussions about."

the real meat on this bone is:


The verneshot theory suggests that mantle plumes may cause heating and the buildup of carbon dioxide gas underneath continental lithosphere. If continental rifting occurs above this location, an explosive release of the built up gas may occur, potentially sending out a column of crust and mantle into a globally dispersive, super-stratospheric trajectory. It is unclear whether such a column could stay coherent through this process, or whether the force of this process would result in it shattering into much smaller pieces before impacting. The pipe through which the magma and gas had travelled would collapse during this process, sending a shockwave at hypersonic velocity that would deform the surrounding craton.

I find that a bit shocking.

Not to mention,


http://en.wikipedia.org/wiki/Diapir

A diapir (/ˈdaɪ.əpɪər/;[1] French, from Greek diapeirein, to pierce through) is a type of intrusion in which a more mobile and ductily deformable material is forced into brittle overlying rocks. Depending on the tectonic environment, diapirs can range from idealized mushroom-shaped Rayleigh–Taylor-instability-type structures in regions with low tectonic stress such as in the Gulf of Mexico to narrow dikes of material that move along tectonically induced fractures in surrounding rock. The term was introduced by the Romanian geologist Ludovic Mrazek, who was the first to understand the principle of salt intrusion and plasticity. The term "diapir" may be applied to igneous structures, but it is more commonly applied to non-igneous, relatively cold materials, such as salt domes and mud diapirs.

In addition to Earth-based observations, diapirism is thought to occur on Neptune's moon Triton, Jupiter's moon Europa, Saturn's moon Enceladus, and Uranus's moon Miranda.[2]

Diapirs commonly intrude vertically upward along fractures or zones of structural weakness through denser overlying rocks because of density contrast between a less dense, lower rock mass and overlying denser rocks.[citation needed] The density contrast manifests as a force of buoyancy. The process is known as diapirism. The resulting structures are also referred to as piercement structures.[citation needed]

In the process, segments of the existing strata can be disconnected and pushed upwards. While moving higher, they retain much of their original properties such as pressure, which can be significantly different from that of the shallower strata they get pushed into. Such overpressured Floaters pose a significant risk when trying to drill through them. There is an analogy to a Galilean thermometer.[3]

Rock types such as evaporitic salt deposits, and gas charged muds are potential sources of diapirs. Diapirs also form in the earth's mantle when a sufficient mass of hot, less dense magma assembles. Diapirism in the mantle is thought to be associated with the development of large igneous provinces and some mantle plumes.

Explosive, hot volatile rich magma or volcanic eruptions are referred to generally as diatremes. Diatremes are not usually associated with diapirs, as they are small-volume magmas which ascend by volatile plumes, not by density contrast with the surrounding mantle.


http://en.wikipedia.org/wiki/Mantle_plume

A mantle plume is a posited thermal abnormality where hot rock nucleates at the core-mantle boundary and rises through the Earth's mantle becoming a diapir in the Earth's crust.[2] Such plumes were invoked in 1971[3] to explain volcanic regions that were not thought to be explicable by the then-new theory of plate tectonics. Some of these volcanoes lie far from tectonic plate boundaries, e.g., Hawaii. Others represent unusually large-volume volcanism whether on plate boundaries, e.g., Iceland or basalt floods like the Deccan or Siberian traps. The currently active volcanic centers are known as "hot spots". In particular, the concept that mantle plumes are fixed relative to one another, and anchored at the core-mantle boundary, was thought to provide a natural explanation for the time-progressive chains of older volcanoes seen extending out from some "hot spots".

The hypothesis of mantle plumes is not universally accepted. Many of its predictions have not been confirmed by observation.[citation needed] As a result, it has required progressive hypothesis-elaboration, and many variant types have been proposed such as mini-plumes and pulsing plumes. Another hypothesis for unusual volcanic regions is the "Plate model". This attributes volcanoes to passive leakage of magma from the mantle onto the Earth's surface where extension of the lithosphere permits it. This model attributes essentially all volcanism to plate tectonic processes, with volcanoes far from plate boundaries resulting from intraplate extension.[4]

That is freaking awesome, kenaz.

What do you know about the idea that oil and natural gas are continually produced byproducts of volcanic action, rather than a dumb ol' sissified fossil fuel?

What would the people do, if only they knew, that oil and gas are renewable resources, just like lava renews itself continually?

O M G is what I am assuming.

Of course they have been so impregnated by the stupidity of Al Gore and others, they might not be willing to give up the ecological religious fanaticism long enough to think about it.
