Toba in Sumatra a candidate for super volcano ???

The devastating Tusnami was precursor to what is coming in 2012. Toba in Sumatra can explode 100 times more violently than what happened 74,000 years back.

The last supervolcano to erupt was Toba 74,000 years ago in Sumatra. Ten thousand times bigger than Mt St Helens, it created a global catastrophe dramatically affecting life on Earth.

Scientists now find through extrapolation cycle study that the 74,000 years back super volcano in Toba, Sumatra was the warm up for what may be coming in 2012.

Around Toba, increasing harmonic tremors have started after the Tsunami two years back.

It would devastate the planet. Climatologists now know that Toba blasted so much ash and sulphur dioxide into the stratosphere that it blocked out the sun, causing the Earth's temperature to plummet. Some geneticists now believe that this had a catastrophic effect on human life, possibly reducing the population on Earth to just a few thousand people. Mankind was pushed to the edge of extinction.

Well, not sure about the devastation of all life in 2012, Mayan calendar aside...but I do believe Sumatra's going to blow. Krakatoa, Toba, whatever.

[cmsgop]

That would Blow......

Guess that would resolve the global warming issue.

So we only have about 5 years .... with so many places to go, people to see, and things to do - there's not enough time; sorry, that event will have to be rescheduled!

Catastrophism ping?

Late Pleostocene Human Population Bottlenecks. . . (Toba)

"The last glacial period was preceded by 1000 years of the coldest temperatures of the Late Pleistocene, apparently caused by the eruption of the Mount Toba volcano. The six year long volcanic winter and 1000-year-long instant Ice Age that followed Mount Toba's eruption may have decimated Modern Man's entire population. Genetic evidence suggests that Human population size fell to about 10,000 adults between 50 and 100 thousand years ago."

Another headline from the same site. Hmmmm

Earth’s dynamo can malfunction in December 2012 with galactic alignment and that can require extraterrestrial help to sustain intelligent life

The volume of the youngest eruption is estimated at 2,800 cubic km, making the eruption the largest in the Quaternary. Pyroclastic flows covered an area of at least 20,000 square km. Up to 1200 feet (400 m) of Young Toba Tuff is exposed in the walls of the caldera. On Samosir Island the tuff is more than 1800 feet (600 m) thick. Ash fall from the eruption covers an area of at least 4 million square km (about half the size on the continental United States). Ash from the eruption has been recovered from deep-sea cores taken in the Bay of Bengal and in India, roughly 300 miles (500 km) inland (1,900 miles, 3100 km from Toba). Rose and Chesner suggested the ash may have reached central Asia and the Middle East. Ninkovich and others (1978) estimated of the height of the eruption column to be 30 to 50 miles (50 to 80 km) for the Young Toba Tuff. Rose and Chesner, after a study of the shapes of the ash shards, concluded this estimate was too high by a factor of 5 or more.

Ten thousand times bigger than Mt St Helens last time it erupted, and next time it could be 100 times more violent than that?

....so thats....

1 million times bigger than Mt St Helens?

Oh man...

[To Hell With Poverty]

I thought it was going to be the Yellowstone supervolcano that's going to do us all in...

Some geneticists now believe that this had a catastrophic effect on human life, possibly reducing the population on Earth to just a few thousand people.

Well, that would certainly solve the population problem. Planned Parenthood can relax.

[GATOR NAVY]

Guess that would resolve the global warming issue.

Start putting the miles on those SUVs people! We need to get a head start on the warming!

[I see my hands]

Tobal Warning.

[Mad_Tom_Rackham]

That would certainly take care of the "global warming" problem.

[SandRat]

Would solve the problem with liberals too; since country boys can survive.

[SpaceBar]

A recent theory that seems quite credible is that the eruption of Toba some ~70k years ago caused a "genetic bottleneck" in homo sapiens resulting in a lack of genetic diversity (race is actually a minor difference) and early migratory routes from eastern Africa that resulted in the geographic distribution of people and cultures we see today.

More information here for the interested.

Tobal Ligation!

[b4its2late]

Somebody's doommed!

[GSlob]

If one is to believe Richard Lynn, it was the glacial periods, global coolings and ice ages which led to the evolution of superior intelligence in those who survived them. In the places where there was no ice age, paleolithic IQs still obtain.
