The Most Incredible Volcano Video of ALL Time



From the description on YouTube:

"The Most Incredible Volcano Video ever shot ! Geoff Mackley, Bradley Ambrose, Nathan Berg, after an epic struggle with the weather for 35 days, we became the first people ever to get this close to Marum Volcano's famed lava lake on Ambrym Island, Vanuatu. Coming within 30 metres of the lava lake down a watercourse, it was possible to stand the heat for only 6 seconds. With Fire Brigade breathing apparatus and heat proof proximity suit it was possible to stand on the very edge and view the incredible show for over 40 minutes.

For those of you "upset" with the use of a watermark on this video it may pay to consider for a moment that my expeditions are funded by the sale of such footage.
This expedition took nearly 2 months and cost many tens of thousands of dollars, not to mention the dangers involved.

As has been seen time and time again, there are many media organizations out there who think nothing of downloading peoples footage, re uploading to their own websites with adverts etc while others pay for the legitimate use of it. Its straight out theft.
Thanks to the viewers who understand why I have to deface such a good video with a watermark."

More from Eyjafjallajokull

"As ash from Iceland's Eyjafjallajokull volcano continued to keep European airspace shut down over the weekend, affecting millions of travelers around the world, some government agencies and airlines clashed over the flight bans."

Did Ancient Volcano Alter Human History?

"An ancient volcanic super-eruption, one of the largest known in Earth's
history, may not have devastated the world and humanity as much as once
thought.

The eruption at what is now Lake Toba in the Indonesia island of
Sumatra roughly 75,000 years ago was the largest in the last 2 million
years. This gigantic blast released at least 7.7 trillion tons or 670 cubic miles of magma, equivalent in mass to more than 19 million Empire State Buildings.

Vast plumes of ash stretched from the South China Sea to the Arabian
Sea and likely blotted out the sun and drastically cooled the Earth for
years—a "volcanic winter." Scientists have suggested the environmental
catastrophe that might have resulted could have influenced the course
of human history, with people today evolving from the few thousand survivors of that disaster.

Newly unearthed prehistoric artifacts now suggest the blast might not
have been "as catastrophic as before thought," said Cambridge
University archaeologist Michael Petraglia.

Indirect clues

Petraglia and his colleagues investigated deposits of ash from Toba more than eight feet thick near the southern Indian village of Jwalapuram. They found hundreds of
stone blades and other tools just below and above this ash layer—effectively immediately before and after the eruption—that are fairly similar to each other. With the artifacts, they also found pieces of red ochre, a mineral used for body art and cave drawings, as well as for helping to stick tools together.

The artifacts appeared similar to some from modern humans dating to
around the same time period in Africa. These findings suggest humans
continued to live in the area after the blast.

"We would have had very mobile populations of hunter-gatherers here, able to cope with all sorts of disasters," Petraglia told LiveScience. "If we were talking about settled people with agriculture, the Toba super-eruption would have been a cataclysm."

The research was detailed in the July 6 issue of the journal Science.

More evidence needed

Not everyone thinks the new evidence is convincing. Anthropological archaeologist Stanley Ambrose at the University of Illinois at Urbana-Champaign, who proposed that the Toba catastrophe influenced human evolution, found the published data inadequate.

"The only way to prove their assertions is to find human skeletons below the ash that look like Africans," Ambrose said.

Petraglia said they had "thousands more artifacts than we presented in the paper" to support the new claim, but did agree that fossils would be definitive proof. "We don't have human fossils, we don't have Neanderthal fossils, we don't have any fossils. We'd love to find fossils," Petraglia said.

An exciting but controversial aspect of their findings is that modern humans got out of Africa far earlier than was thought. "For the last 150 years, archaeologists
have concentrated on when modern humans got out of Africa into Europe, but our findings suggest they might have gotten to India 30,000 years before they got to Europe," Petraglia said.

"There's a lot of really remarkable archaeology that can be done in India that we're excited about exploring," he said."
