Was the great flood fiction? The volcanos answer.

As you know, one of the arguments against the historical validity of the great flood (or should I call it biblical flood?!) is that the events described in the Bible are impossible and the story probably reflects a local event. As you know, I'm not a great fan of the Bible as a religious book or like erm, scientific proof, but still the legends of the Great Cataclysm that destroyed Atlantis and other tribes/people/civilisations is quite well-present and repeating again and again. I'm not going to go into archaeology here, there are enough books to read on the issue. I recommend "Underworld: The Mysterious Origins of Civilisation" by Graham Hancock. It's not the answer to everything, but it's a good start and I like how the guy got down and filmed everything. I hate books written just for the money.

Anyway, today, let's focus on physics. As we know, people tend to claim it's impossible to have the events described in those legends, since they are weird. Like freaky mists that choked everyone in sight, trembling of the ground, floods, deadly rain and whatever. If you think carefully on all those, they are quite possible. And the following articles proove it. As for me, I don't understand why people refuse to look into the pre-flooded world and what may lies there. And I don't understand why we all follow the Sumer-Egypt and semitian path in history while we leave so many others untouched. Like the Trackian civilisation in Bulgaria, like the Di(n)li civilisation in Asia, like the Indian civilisation and South America's. We like to talk about them like exotics and not to try to fit them in any sensible chronology. And we miss a lot. What about Atlantis? Where does it fit in our pro-semitian archaelogy. What about the rest of the world, that were blond/red haired and blue/green eyed or those that were black or those that were red? Racism takes weird turns :)
Ok, let's not go there now. Let's stick to the science.

Volcano spews lethal acid brew

ALL the fish and birds were gone, the trees were defoliated and their mosses dead, and the local lakes and rivers were lined with yellow scum. This was the aftermath of a mysterious catastrophe in July 2005, as reported by a lodge-owner near the remote Chiginagak volcano in Alaska.

A group of geologists has now pieced together what happened. In May 2005, they say, a torrent of sulphurous liquid and mist gushed from the volcano's icy crater, leaving a trail of sulphur deposits and turning salmon spawning-grounds as acidic as lemon juice.

"We haven't seen an event like this in the historical record," says Johan Varekamp of the Wesleyan University in Middletown, Connecticut, who reviewed the group's work.

...November
2004. Sometime after that, heat from the underlying magma melted the bottom of the ice,
says Janet Schaefer of the Alaska Volcano Observatory in Fairbanks.
They say that as the ice melted sulphur dioxide and other gasses bubbled up, acidifying the
meltwater. By early May 2005, the water had carved a tunnel through the base of the glacier, releasing almost 4 million cubic metres of mud, rocks and highly acidic water .
The floodwater reached Moth Goose lake, 27 kilometres from the volcano, wiping out life in th
lake and preventing salmon from making their annual journey to their spawning grounds.
Schaefer’s team sampled the lake water and found its pH to be 3, similar to lemon juice.

But Schaefer’s colleague William Scott at the US Geological Survey in Vancouver
Canada, says the unusual aspect of the Chiginagak event was the dense and lethal acidic mist.

Schaefer says the gasses may have burst from the meltwater when it was suddenly released from the crater, or that the violent flow created a mist like that around a waterfall. The cloud killed plants over 30 square kilometres and 150 metres above the valley floor.
Acidic liquid is still oozing from the Chiginagak crater, but surrounding ecosystems are
recovering.

My comment: The part after the ... is from the original article. As you can see, mists from volcanos can be very deadly in big regions. And that's a single volcano. What could happen if the whole Earth crust is disrupted and there are major earthquakes and volcano, I'll live it to the imagination of Hollywood workers.

Arctic volcanoes exploded at 'impossible' depth

The deep ocean continues to surprise – it appears that volcanoes on the Arctic seabed have blown up at depths where such events were thought impossible.

In 1999, the largest-ever swarm of quakes on a mid-ocean ridge was recorded, on the Gakkel Ridge in the east Arctic basin.

To find out what caused it, Robert Reves-Sohn of the Woods Hole Oceanographic Institution in Massachusetts, US, and colleagues peeked at the ridge with robot subs and various sensors used to search under pack ice.

They found shattered rock spread over 10 square kilometres, suggesting a series of volcanic explosions.

Such explosions can occur in shallower water if hot lava rapidly vaporises the surrounding seawater, but beyond 3 kilometres down the pressure is too high for this to happen.

Gassy build-up

To explain the destruction his team found, Reves-Sohn says the lava must have contained 10 times more carbon dioxide than the highest value ever measured in mid-ocean-ridge rocks. He suggests that the CO2 bubbled out of the rising lava and built up in a chamber beneath the seabed.

Seismic records show that the explosions were preceded by a series of earthquakes. The researchers believe these will have cracked the roof of the CO2 chamber. The gas and magma then burst out, scattering fragments of cooled rock over the bottom.

The researchers calculate that for the rock fragments to have scattered over 10 square kilometres, the CO2 chamber must have been several kilometres beneath the seafloor. An explosion of this type would have created explosive fountains rising up to 2 km in the water column.

The volcanic events at Gakkel Ridge were not a one-off, the team says, and could be ongoing. Similar but smaller explosions were detected by seismometers mounted on the Arctic ice more than two years after the 1999 eruption and the rock fragments observed are of different ages.

Gakkel Ridge is the slowest spreading ridge on Earth. Reves-Sohn and his team believe ultra-slow-spreading ridges create the ideal conditions for deep explosions because they give the CO2 enough time to accumulate into a single chamber.

He says the CO2 also may contribute to shallow-water explosive eruptions that were previously attributed to steam.

My comment: Cool, heh? Goes well with my previous comment. What if this was near inhabited place? Poor Atlantis!

For more on mega-quakes, read here the story of the Parvie fault trough the last Ice Age:

"Knowing the scale of the faults, Arvidsson could calculate the size of the earthquakes that ripped the crust long ago. The largest postglacial fault, the 160-km-long Parvie fault, formed during a magnitude 8.2 earthquake, he estimates. The 50-km-long Lansjarv fault came to life in a shock with a magnitude of 7.8."
