Yikes. Supervolcano found under Hong Kong

Hong Kong geologists have revealed for the first time the full extent of an ancient supervolcano with a diameter of 18km sitting beneath the former British colony.

The giant ash monster is thought to be of the same collapse caldera type as the infamous Krakatau volcano which killed tens of thousands and literally rocked the world when it blasted open near the Indonesian islands of Java and Sumatra in 1883.

The discovery – one of only around 50 such volcanoes in the world – is a coup for the local rock boffins, who have been digging around the Geopark in Sai Kun in the east of the Special Administrative Region for several years.

A supervolcano is one which is capable of producing 1,000 cubic kilometers of ash in an eruption. To put that in perspective, the hugely destructive Krakatau, whose explosion was Read more…

Ice Age, Supervolcano Could Topple US Government

As more evidence mounts that the world is slipping faster into the next Ice Age, Washington insiders are scurrying to solidify their new power base for centralized government operations. Fears that the US capital might be struck by another more deadly terrorist attack—or other disasters—prompted federal agencies more than a decade ago to hurriedly establish back-up operations in case catastrophe struck. Despite the fact that many conspiracy theories are weaved around the subjects that follow—including some fairly wild-eyed, tin foil hat scenarios—most conspiracy theories have a basis in fact, albeit the facts are often distorted or wildly exaggerated. The actual story of the bizarre Denver International airport, the nation’s “second capital,” the impending Ice Age possibility, and the Yellowstone supervolcano threat to America follows…

Volcano expert fears we’ll see a super eruption

Volcanologist Clive Oppenheimer yesterday warned there was a one-in-500 chance of the world being hit by a super- volcano this century.

The reader in vulcanology at Cambridge University told a Hay audience: “That might not sound like much, but it is a lot more likely than an asteroid impact.

“The events in Japan remind us that you can have a tsunami and earthquake and a nuclear plant there as well and you can have these chain reaction events that are actually quite calamitous and they are not unimaginable.”

Examining geological, historical and archeological records, the expert took the audience on a journey back to three volcanic eruptions that have shaken the world – the 1815 Tambora volcano in Indonesia that Read more…

Experts: Mega-Quakes Can Create Pole Shifts

Mega-thrust earthquakes like the ones that recently struck Chile and the Fukushima region of Northern Japan, can cause the magnetic field to flip. If a quake is strong enough there is evidence it may even set off a geological pole shift tossing the Earth off its current axis and killing billions of people within a matter of minutes.

This the grim picture painted by decades of research and evidence strewn from the peaks of the Andes to the volcanic shards lying off the Pacific islands of Hawaii.

Cities could be swept away in the blink of an eye

Enormous earthquakes cause enormous damage. The threat is real and growing, as world renown physicist and popular science author, Dr.Michio Kaku , recently explained on ABC’s “Good Morning America.”

According to Dr. Kaku, some of the world’s most important and populated cities could be swept away in the blink of an eye. “In our life time, we could very well see one of these cities destroyed,” Kaku claimed. “Los Angeles, San Francisco, Mexico City, Tehran, and Tokyo.”

It is actually Mankind and not nature that has placed up to one billion people at risk. “We are creating mega cities where there used to be Read more…

Supervolcano plume sized up

This image, based on variations in electrical conductivity of underground rock, shows the volcanic plume of partly molten rock that feeds the Yellowstone supervolcano. Yellow and red indicate higher conductivity,green and blue indicate lower conductivity.

By John Roach

The volcanic plume beneath Yellowstone is larger than previously thought, according to a new study that measured the electrical conductivity of the hot and partly molten rock.

The findings say nothing about the chances of another cataclysmic eruption at Yellowstone, but they give scientists another view of the vast and deep reservoir that feeds such eruptions.

“It’s a totally new and different way of imaging and looking at the volcanic roots of Yellowstone,” study co-author Robert Smith, an emeritus professor Read more…

Yellowstone supervolcano, new Ice Age could topple US government

Yellowstone Supervolcano Bulges 10 inches as Magma Pocket Swells

January 22, 2011 Comments off

“Yellowstone National Park’s supervolcano just took a deep “breath,” causing miles of ground to rise dramatically, scientists report. The simmering volcano has produced major eruptions – each a thousand times more powerful than Mount St. Helens’s 1980 eruption – three times in the past 2.1 million years. Yellowstone’s caldera, which covers a 25- by 37-mile (40- by 60-kilometer) swath of Wyoming, is an ancient crater formed after the last big blast, some 640,000 years ago. (See “When Yellowstone Explodes” in National Geographic magazine.)
Since then, about 30 smaller eruptions – including one as recent as 70,000 years ago – have filled the caldera with lava and ash, producing the relatively flat landscape we see today. But beginning in 2004, scientists saw the ground above the caldera rise upward at rates as high as 2.8 inches (7 centimeters) a year. (Related: “Yellowstone Is Rising on Swollen ‘Supervolcano.'”) The rate slowed between 2007 and 2010 to a centimeter a year or less. Still, since the start of the swelling, ground levels over the volcano have been raised by as much as 10 inches (25 centimeters) in places. “It’s an extraordinary uplift, because it covers such a large area and the rates are so high,” said the University of Utah’s Bob Smith, a longtime expert in Yellowstone’s volcanism.Yellowstone Takes Regular Breaths: Read more…
