Mayon Volcano Expected To Blow

Pyroclastic flows from Mayon 1984
Active Philippines Volcano Could Erupt Within Days

The Philippines' most active volcano could erupt within days, officials warned Sunday after detecting a drastic surge in earthquakes and eerie rumbling sounds in surrounding foothills. Tens of thousands of villagers have been evacuated as a precaution.

Scientists raised the alert level for the Mayon volcano to one step below a major eruption after 453 volcanic earthquakes were detected in a five-hour span Sunday, compared to just over 200 Saturday, said Renato Solidum, chief of the Philippine Institute of Volcanology and Seismology.

Army troops and police will intensify patrols to enforce a round-the-clock ban on villagers within a five-mile danger zone around the 8,070-foot mountain, said Gov. Joey Salceda of Albay province, about 210 miles southeast of Manila.

The massive evacuations were unfortunate, coming so close before Christmas, Salceda said, but authorities will find ways to bring holiday cheer to displaced villagers in emergency shelters.

The cone-shaped volcano has already belched a plume of grayish ash half a mile into the sky, and red-hot lava has flowed about 2.8 miles down the mountainside, he said.

Residents who briefly returned to their homes within the danger zone to check on their belongings reported hearing eerie rumbling sounds.

More than 40,000 villagers have been moved to school buildings and other emergency shelters, and they should be warned from venturing back now due to the extreme danger, volcanologist July Sabit said.

Superheated gas and volcanic debris can race down the slopes at very high speed, vaporizing everything in their path.

"It's extremely dangerous," Sabit told The Associated Press by telephone.

Residents are used to playing a "cat and mouse" game with Mayon, a popular tourist attraction because of its near-perfect cone shape.

Mayon last erupted in 2006, when about 30,000 people were moved. Another eruption in 1993 killed 79 people.

The first recorded eruption was in 1616 but the most destructive came in 1814, killing more than 1,200 people and burying a town in volcanic mud. The ruins of the church in Cagsawa have become an iconic tourist spot.

The Philippines lies along the Pacific "Ring of Fire," where volcanic activity and earthquakes are common. The Philippines has 22 active volcanoes.

Associated Press writer Jim Gomez contributed to this report from Manila.

Maybe we could get some people from the EPA(environmental protection agency)to go there and tell the volcano that all emissions like this are now being tightly regulated. As I have stated numerous times, "volcanos and their effects are what man needs to be worrying about, not, emissions that humans are making".

Yellowstone Super-Volcano

Mayon Volcano Legazpi City, Philippines
Yellowstone Super-Volcano Far More Dangerous Than Previously Thought

The most detailed seismic images yet published of the plumbing that feeds the Yellowstone super-volcano shows a plume of hot and molten rock rising at an angle from the northwest at a depth of at least 410 miles, contradicting claims that there is no deep plume, only shallow hot rock moving like slowly boiling soup.

A related University of Utah study used gravity measurements to indicate the banana-shaped magma chamber of hot and molten rock a few miles beneath Yellowstone is 20 percent larger than previously believed, so a future cataclysmic eruption could be even larger than thought.

The study's of Yellowstone's plume also suggests the same "hotspot" that feeds Yellowstone volcanism also triggered the Columbia River "flood basalts" that buried parts of Oregon, Washington state and Idaho with lava starting 17 million years ago.

Those are key findings in four National Science Foundation-funded studies in the latest issue of the Journal of Volcanology and Geothermal Research. The studies were led by Robert B. Smith, research professor and professor emeritus of geophysics at the University of Utah and coordinating scientist for the Yellowstone Volcano Observatory.

"We have a clear image, using seismic waves from earthquakes, showing a mantle plume that extends from beneath Yellowstone,'' Smith says.

The plume angles downward 150 miles to the west-northwest of Yellowstone and reaches a depth of at least 410 miles, Smith says. The study estimates the plume is mostly hot rock, with 1 percent to 2 percent molten rock in sponge-like voids within the hot rock.

This is not exactly the kind of news You want to hear, however, it is fact! While governments are gathering and fighting amongst themselves about global warming/climate control, "volcanos" are what they need to be paying attention to. If a "super volcano" like Yellowstone, Toba, in Indonesia, Krakatoa, Mt Vesuvius, or Mt Fuji, just to name a few, decided to have a major blow, it's pretty much game over. It's not a matter of "if", it's just a matter of "when"!

Earth Devastated By Volcano

Prehistoric Volcano Devastated Earth

A massive volcanic eruption that occurred in the distant past killed off much of central India's forests and may have pushed humans to the brink of extinction, according to a new study that adds evidence to a controversial topic.

The Toba eruption, which took place on the island of Sumatra in Indonesia about 73,000 years ago, released an estimated 800 cubic kilometers of ash into the atmosphere that blanketed the skies and blocked out sunlight for six years. In the aftermath, global temperatures dropped by as much as 28 degrees Fahrenheit and life on Earth plunged deeper into an ice age that lasted around 1,800 years.

In 1998, Stanley Ambrose, an anthropology professor at the University of Illinois, proposed in the Journal of Human Evolution that the effects of the Toba eruption and the Ice Age that followed could explain the apparent bottleneck in human populations that geneticists believe occurred between 50,000 and 100,000 years ago. The lack of genetic diversity among humans alive today suggests that during this time period humans came very close to becoming extinct.

To test his theory, Ambrose and his research team analyzed pollen from a marine core in the Bay of Bengal that had a layer of ash from the Toba eruption. The researchers also compared carbon isotope ratios in fossil soil taken from directly above and below the Toba ash in three locations in central India — some 3,000 miles from the volcano — to pinpoint the type of vegetation that existed at various locations and time periods.

Heavily forested regions leave carbon isotope fingerprints that are distinct from those of grasses or grassy woodlands.

The tests revealed a distinct change in the type of vegetation in India immediately after the Toba eruption. The researchers write in the journal Palaeogeography, Palaeoclimatology, Palaeoecology that their analysis indicates a shift to a "more open vegetation cover and reduced representation of ferns," which grow in humid conditions, all of which "would suggest significantly drier conditions in this region for at least 1,000 years after the Toba eruption."

The dryness probably also indicates a drop in temperature "because when you turn down the temperature you also turn down the rainfall," Ambrose said. "This is unambiguous evidence that Toba caused deforestation in the tropics for a long time."

He also concluded that the disaster may have forced the ancestors of modern humans to adopt new cooperative strategies for survival that eventually permitted them to replace Neanderthals and other archaic human species.

Although humans survived the event, researchers have detected increasing activity underneath a caldera at Yellowstone National Park, where some suspect another supervolcanic eruption will eventually take place. Though not expected to occur anytime soon, a Yellowstone eruption could coat half the United States in a layer of ash up to 3 feet deep.

So, when are humans going to realize that going to Copenhagen for a "global climate" summit is a waste of time, money and resources? And why do the people on the street with a brain know this is an exercise in futility, yet, governments don't know this, OR, have hidden agendas and don't want to know. "We cannot fix something that we cannot break". Only the universe and the planet control what goes on with the Earth. When are these so called intelligent life forms(humans), going to figure this out and STOP perpetrating their fraud on the rest of us?

As I and others have been saying, "the planet is not going anywhere, however, we are, we're going away sooner than You may think".....

Volcanic Lightning In Eruption(Redoubt)

Volcano's Lightning Captured in Photo

(April 8) - For the first time, scientists have been able to "see" and trace lightning inside a plume of ash spewing from an actively erupting volcano.

When Alaska's Mount Redoubt volcano began rumbling back to life in January, a team of researchers scrambled to set up a system called a Lightning Mapping Array that would be able to peer through the dust and gas of any eruption that occurred to the lightning storm happening within. Lightning is known to flash in the tumultuous clouds belched out during volcanic eruptions.

The lightning produced when Redoubt finally erupted on March 22 was "prolific," said physicist Paul Krehbiel of New Mexico Tech.

"The lightning activity was as strong or stronger than we have seen in large Midwestern thunderstorms," Krehbiel said. "The radio frequency noise was so strong and continuous that people living in the area would not have been able to watch broadcast VHF television stations."

Lightning mapping arrays are increasingly being used by meteorologists to issue weather warnings, but have only been deployed at volcanoes twice before.

Thousands of individual segments of a single lightning stroke can be mapped with these arrays, and later analyzed to reveal how lightning initiates and spreads through a thunderstorm, or in a volcanic plume.

After setting up the arrays, researchers waited nearly two months for Redoubt's first eruption, but the wait was worth it.

"For the first time, we had the Lightning Mapping Array on site before the initial eruption," said scientist Sonja Behnke of New Mexico Tech.

The eruptions that continued to occur on March 22 and 23 provided plenty of data, and the arrays returned dramatic information about the electricity created within volcanic plumes, and the resulting lightning. As of today, Redoubt has erupted several times since its initial eruption on March 22.

"The data will allow us to better understand the electrical charge structure inside a volcanic plume," said scientist Ron Thomas of New Mexico Tech. "That should help us learn how the plume is becoming electrified, and how it evolves over time."

A recent study in the journal Nature found that volcanic plumes spin like tornadic thunderstorms, a finding which helps to explain the lightning storms, as well as the waterspouts and dust devils produced by some volcanic plumes.

The New Mexico Tech researchers plan to compare the Redoubt data with observations taken from Chaiten Volcano in Chile last year. The project was funded by the National Science Foundation.

Redoubt hasn't finished making noise yet; after quieting down for a few days, Redoubt exploded again, with the last major eruption occurring on March 28. Scientists at the Alaska Volcano Observatory expect the eruptions will continue periodically for weeks to months.

Volcanoes are probably the most amazing things on the planet. As terrifying as they are and can be, without them, we wouldn't have any land to live on. They are utterly fascinating!

"Dead" Volcano Erupts Again


Chaiten Volcano Erupts in Chile

SANTIAGO, Chile (Feb. 20) - More than 150 people who had returned to a Chilean town destroyed by a volcanic eruption last year were evacuated again on Thursday as the volcano roared back to life, spewing ash high into the air.

The explosion apparently rocked the dome of the Chaiten volcano and sent volcanic material down the mountain's slope, threatening to block a river and trigger flooding, said Paula Narvaez, a presidential delegate to the area in southern Chile.

Experts who flew over the volcano reported "large emanation of gas" on Thursday and said the situation is risky for the nearby seaside town of Chaiten because rains could trigger avalanches.

"The experts were unanimous in considering that no one must remain in Chaiten," Chile's Emergency Bureau said in a communique.

Narvaez said that as many as 160 people were evacuated from the vicinity of the 2,700-foot volcano.

More than 4,000 people were initially evacuated after Chaiten erupted on May 2 for the first time in an estimated 9,000 years.

On Thursday, increased seismic activity was reported and ash fell 100 miles away in Futaleufu.

Some residents of Chaiten, six miles from the like-named volcano, have strongly resisted government efforts to relocate them to a new settlement following the devastating eruption last year.

Residents opposed to the move in recent weeks staged protests in the town's ruins, amid houses buried under ash and volcanic mudflows.

Narvaez said the situation on Thursday "was exactly the kind of danger we were talking about when we decided to relocate Chaiten."

The relocation site has yet to be determined.

For the second time in less than a year Chaiten volcano has erupted after being dormant for over 9000 years. We will keep an eye on this volcano and story. People, "just pay attention to things that are taking place on the planet. A shift is coming and some things have already been set in motion".
