Super Volcano: Cataclysm in 535 A.D.
 Because I think the Yellowstone caldera 
presents such a danger, here’s an article by 
Michael Relfe that you might want to read.

 

"In AD 535/536 mankind was hit by one of the greatest natural disasters ever to occur …… It blotted out much of the light and heat of the sun for 18 months and resulted, directly or indirectly in climatic chaos, famine, migration, war and massive political change on virtually every continent".

This is in the opening page of Catastrophe by David Keys, 1999, a book that should have been on the best seller lists. The book took four years to write and research, and is extremely well researched.

It is likely that the cause of this catastrophe was the eruption of the super volcano Krakatoa. During this time, many trees did not grow at all. This event was followed by 30 years of unprecedented droughts and some flooding. This caused the death of a vast percentage of the population through starvation and disease

The contemporary Roman historian Procopius described the mystery climatic disaster: "The sun gave forth its light without brightness like the moon during this whole year.""

Sixth century historian and prominent church leader John of Ephesus wrote of 535 AD in his Historiae Ecclesiasicae (Church Histories), "There was a sign from the sun, the like of which had never been seen and reported before. The sun became dark and its darkness lasted for 18 months. Each day, it shone for about four hours, and still this light was only a feeble shadow. Everyone declared that the sun would never recover its full light again.""

In Italy a Senior local civil servant, Cassiodorus Sentaro wrote in 536, "We marvel to see no shadows of ourselves at noon ....We have had a spring without mildness and a summer without heat."

Here is more evidence from the book that there was a major global disaster in 535 AD.

"Continuous tree-ring chronologies, going back to the 6th century AD and beyond, exist for Finland, Sweden, the British Isles, central Europe, the Aegean, Siberia, North America, Chile, Argentina and Tasmania. In a substantial percentage …… the period 535 – 550 stands out as a time of unusually low tree-ring growth. In several key chronologies, that 25-35 year period contains many of the narrowest ring sequences known for the past 2,000 years…. From 538 or, in many places, 540, there was an almost universal massive decline lasting between two and eight years……This was particularly marked in the Southern Hemisphere."

"A recent total reassessment of the evidence has now led archaeologists to re-date the collapse of the great Mexican city of Teotihuacan to the Sixth Century A.D….An American anthropologist, Rebecca Storey of the University of Houston, has analyzed data from more than 150 skeletons … Her findings reveal that in the years prior to the collapse, 68.3% of the working class population were dying before the age of 25, compared to 38.6% in more normal times."

Keys argues persuasively that it was this climatic disaster that indirectly caused the many plagues at that time, including the ‘Great Death’. Extrapolating from death rates of the much better recorded plague in the 14th Century, in Britain possibly somewhere between 60% and 90% died of plague, both peasants and members of the elite.

What caused the global cataclysm?

The most likely culprit is a super volcano, because in order to dim the sun, tons and tons of dust had to be thrown into the sky. A super volcano can do this by forcing huge quantities of sulphur into the stratosphere, which become sulphuric-acid aerosols, capable of staying aloft and directly changing the weather for several years.

The final clinching evidence, however, comes from 10,000 miles to the south – from deep inside the Antarctic ice cap. … Scientists, again using ice-cores, discovered evidence of a truly massive volcanic eruption. The ice-core material revealed that acid snow had cascaded down on the Antarctic for at least four years running….(This) occurred sometime between 490 and 540."

It is very possible that both Greenland and Antarctica events were the same event.

So, then the next question is, which volcano was the culprit?

Keys pinpoints the culprit as "Krakatoa, the notorious island mountain which brought death and destruction to Java and Sumatra in the 1880s. "Today, all that is left of this massive collapse is a 25-mile diameter, mainly underwater caldera … among the half-dozen largest calderas ... in the world."

Could such a catastrophe happen again?

In Yellowstone National Park is the world’’s largest dormant volcano. It covers 1,500 square miles. It will almost certainly one day burst forth upon the world as Krakatoa did. "It appears to erupt roughly once every 600,000 – 700,000 yeas – and the last eruption was exactly 630,000 years ago… What’s more, the last decade has seen a substantial increase in potential pre-eruption activity".

Keys wrote in 1999: "Since 1988, upward pressure exerted by the magma reservoir and magma-heated water-vapour has forced hundreds of square miles of land to rise by three feet …

Another potential catastrophe is a currently dormant super-volcano in Long Valley, California. Keys wrote in 1999: "Over the past 20 years, this too appears to have become progressively less stable…What’s more, earthquake clusters are becoming much more intensive…

Beneath Naples in Italy is another super volcano. "Since 1969, pressure from this magma has caused land to rise and fall twice – by almost 6.5 feet. In the early 1980s, it generated up to 300 small earthquakes per week. It’s been known to have erupted catyclysmically twice – once 37,000 years ago… and once 12,000 years ago….

The fourth truly major volcanic caldera currently displaying ominous signs of increasing restlessness is that of Rabaul in Papua New Guinea…. Five other large potentially active caldera volcanoes exist in the Alaskan Aleutian Islands and Mexico….If any one of these volcanoes explode, world climate would be plunged into chaos, precisely as it was in the sixth century".

Keys says that when Yellowstone blows, Las Vegas and Phoenix will be covered with a three foot layer of ash.

As for timing of Yellowstone, a BBC Documentary mentioned above had this to say: Steve Sparks: It is actually very difficult to say for sure what is happening underneath a volcano like Yellowstone. It could be that the next super eruption is another hundred thousand years from now or it could be tomorrow. http://www.abc.net.au/catalyst/stories/s1343737.htm#transcript
