Is Bigger Icelandic Eruption on the Way?

Stay tuned trans-Atlantic travlers! - HLG


REYKJAVIK, Iceland — For all the worldwide chaos that Iceland's volcano has already created, it may just be the opening act.

Scientists fear tremors at the Eyjafjallajokull volcano could trigger an even more dangerous eruption at the nearby Katla volcano — creating a worst-case scenario for the airline industry and travelers around the globe.

A Katla eruption would be 10 times stronger and shoot higher and larger plumes of ash into the air than its smaller neighbor, which has already brought European air travel to a standstill for five days and promises severe travel delays for days more.

The two volcanos are side by side in southern Iceland, about 12 miles apart and thought to be connected by a network of magma channels.

Katla, however, is buried under ice 550 yards thick -- the massive Myrdalsjokull glacier, one of Iceland's largest. That means it has more than twice the amount of ice that the current eruption has burned through -- threatening a new and possibly longer aviation standstill across Europe.


Hundreds have been evacuated and tens of thousands of flights canceled after a volcano in Iceland erupted beneath a glacier, filling the skies over Europe with ash.



Travelers Remain StrandedAirlines gradually take to skies
Katla showed no signs of activity Tuesday, according to scientists who monitor it with seismic sensors, but they were still wary.

Pall Einarsson, professor of geophysics at the Institute of Earth Sciences at the University of Iceland, said one volcanic eruption sometimes causes a nearby volcano to explode, and Katla and Eyjafjallajokull have been active in tandem in the past.

In fact, the last three times that Eyjafjallajokull erupted, Katla did as well.

Katla also typically awakens every 80 years or so, and having last exploded in 1918 is now slightly overdue.

That notion is frightening for nearby villagers, who would have to quickly evacuate to avoid the flash floods that would rip down Katla's slopes. Even last week's eruption generated spectacular cascades of melted water and ice chunks the size of houses when burning gases and molten earth carved through the glacier.

Svenn Palsson, the 48-year-old mayor of the coastal village of Vik, said residents are going over evacuation plans now just in case.

With a population of 300, Vik has been covered in 0.12 inches of ash from the Eyjafjallajokull eruption, but the real concern is Katla. Residents would have two to three hours to reach the safety of a shelter if the volcano erupted and caused the ice to melt quickly.

"We have practiced and can do it in 30 minutes," Palsson said.

Other areas around the mountain, however, would have no more than 20 minutes to evacuate, he said.

Katla's substantial ice cap is a major worry because it's that mixture of melting cold water and lava that causes explosions and for ash to shoot into high altitudes. Strong winds can then carry it on over Europe.
So far there have been minor tremors at Katla, which scientists believe to be movements in the glacier ice, but the activity from Eyjafjallajokull is making measurements more difficult to read and an eruption more tricky to predict.

"It is more difficult to see inside Katla," said Kristin Vogfjord, geologist at the Icelandic Met Office.

Her team of geophysicists, based in the capital of Reykjavik, use seismometers and GPS units planted around volcanoes to monitor quakes and the swelling of the land, which can indicate magma reservoirs that are pushing up through the crust. The area around Eyjafjallajokull rose up as much as 3 inches in recent months and then contracted slightly following the latest eruption.

Vogfjord says Katla's sensitivity to eruptions at Eyjafjallajokull may have to do with pressure shifts in the Earth's crust that are caused by an eruption's magma flow.

There are no clear answers, however, and even fewer predictions about what the future may hold. Volcano eruptions, like earthquakes, are difficult to predict.

"Katla can start tomorrow or in 100 years, you don't know," said Palsson. "All we can do is be ready."

Volcanic ash cloud: Met Office blamed for unnecessary six-day closure

By By Caroline Gammell, David Millward and Bruno Waterfield
Published: 10:06PM BST 19 Apr 2010

Link to this video The government agency was accused of using a scientific model based on “probability” rather than fact to forecast the spread of the volcanic ash cloud that made Europe a no-fly zone and ruined the plans of more than 2.5 million travellers in and out of Britain.

A senior European official said there was no clear scientific evidence behind the model, which air traffic control services used to justify the unprecedented shutdown.



Legal experts suggested passengers and airlines may be able to sue the Government for more than £1?billion in compensation. Flights in and out of Britain are scheduled to resume today for the first time in almost a week after Lord Adonis, the Transport Secretary, said there had been a “dramatic decrease” in the volcano’s activity.

Airports in Scotland and the north of England will be the first to open, followed by those in the Midlands and then in the south of England by 6pm.

However, it has been estimated that the travel backlog could take up to a fortnight to clear.

British airspace was shut for the first time in history last Thursday amid fears that the volcanic ash from Iceland could get sucked into jet engines and cause them to malfunction.

The announcement last night that restrictions would be eased was accompanied by arguments over whether the shutdown had been an over-reaction.

Much of the blame was directed at the Met Office’s Volcanic Ash Advisory Centre (VAAC). It provided the initial warning, which triggered the European-wide ban via Eurocontrol, the air traffic control centre in Brussels.

Matthias Ruete, the European Commission’s director-general of transport, said air traffic authorities should not have relied on a single source of scientific evidence before imposing the widespread ban. He suggested the no-fly zone should have been restricted to a 20 to 30-mile limit around the volcano. “The science behind the model we are running at the moment is based on certain assumptions where we do not have clear scientific evidence,” he said.

“We don’t even know what density the cloud should be in order to affect jet engines. We have a model that runs on mathematical projections.

It is probability rather than actual things happening.”

Mr Ruete said the commission had to intervene to allow airlines to make test flights in order to check the VAAC data “to help us move on from the mathematical model”.

Of the 40 test flights across Europe, including a British Airways flight on Sunday, none found any evidence of ash in jet engines, windows or lubrication systems.

In a joint letter to Lord Adonis, the 11 British airlines said the official response to the volcanic eruption presented “a clear case for government compensation”.

Jeff Zindani, of Forum Law solicitors, said: “Legal analysis suggests that there may be a raft of class actions brought by airlines and companies that are dependent on air travel to move their goods.

“This may well open the way for wider litigation against the Met Office and other government agencies who are found to have failed in their duty of care. The damages and legal costs could break the £1?billion mark.”

Andy Harrison, the chief executive of easyJet, said the cost could run into “hundreds of millions of pounds”.

The International Air Transport Association (Iata), the airline industry trade body, also criticised the decision to close airspace based on theoretical modelling of the ash cloud.

“These decisions have been taken without adequately consulting the airlines. This is not an acceptable system particularly when the consequences for safety and the economy are so large,” said Giovanni Bisignani, the organisation’s director general.

He said the £1?billion cost to the aviation industry could be attributed to lost revenue, repatriation, refunds and the cost of supporting stranded passengers. The cost to the wider British economy has been estimated at £500? million.

British Airways announced it planned to begin flying from London from 4pm after Willie Walsh, its chief executive, said the blanket ban had been “unnecessary”. Virgin Atlantic said it hoped to operate flights from London from 7pm.

Mr Walsh was one of the 11 signatories of the letter to Lord Adonis. It said: “We remain concerned that the approach taken by Nats has been too sweeping.” Warning of “long-term damage” to the industry, it added: “We believe that the nature of this natural disaster presents a clear case for government compensation. The closure of airspace is an uninsurable event and thus not a risk that airlines can reasonably be expected to bear.”

David Greene, the head of litigation at Edwin Coe, said legal action was more likely to be successful if taken by a large group of tourists and companies in a class action.

Interesting Tornado Post on NOAAs Severe Weather Blog (we should add a link)

Can tornado activity through April portend May?
Apr 16th, 2010 | By Greg Carbin | Category: U.S. Severe Weather Blog

Short answer: apparently not! Longer answer follows.

Few tornadoes have occurred to date in 2010, especially when compared to very active recent years such as 2008. The adjusted annual tornado trend shown below indicates that 2010, with 79 tornadoes (adjusted) through April 15, is rapidly approaching the minimum number of tornadoes expected through this time of year (about 75). While 2010 has not quite reached that adjusted minimum threshold yet, it looks like it may be only a matter of another day or two with few or no tornadoes.


This graph shows how the number of tornadoes so far in 2010 in the United States is very near the adjusted minimum value expected. Additional information about the chart and the method used to adjust for tornado report inflation can be found here: http://www.spc.noaa.gov/wcm/adj.html
Does the scarcity of tornadoes so far in 2010 say anything about what we can expect for tornado activity in May? Let’s review the past 30 years of tornado counts and see. Below is a chart depicting the departure from the decade’s average number of tornadoes for two periods in each year (1980-2009). The first period is the departure from the decade’s average number of tornadoes, January through April (gold). The second period is the departure from the decade’s average number of May tornadoes (light blue). In the early years of this chart (1980 through 1983), this chart would suggest that, yes, we can say that an above (below) average start to the year through April is indicative of a above (below) normal May. However, that forecast methodology falls apart in 1984, 1985, and 1986 when, in each of those years, an above normal January-April period was followed by a below normal May. In 1987 and 1988, there is a strong correspondence between a low number of tornadoes through April, and a slow (below normal) May. Then in 1989, an inverse relationship occurs when a below normal start to the year is followed by an above normal May.


With the exception 1995, there is a remarkable 13 year stretch from 1990 to 2002 when the start of the year could possibly be used as an indicator of the May to come. During this period there were nine years when normal to below normal tornado numbers in the January through April period were followed by normal to below normal tornado activity in May. There were only three years during this period (1991, 1998, and 1999) when an above normal start to the year continued into May. If you were looking at only those years you might conclude that in 2010 we will see below normal tornado activity into May.

Trouble starts again in 2003 and 2004 when low tornado counts through the early months of the year are followed by remarkably active Mays. In fact, May 2003 and May 2004 are the most anomalously active Mays of the 30-year period and both were preceded by some of the most anomalously inactive January through April periods! Some semblance of correspondence returns in 2005 (both periods below normal) before a reversal shows up in 2006 and 2007 with above normal January through April periods being followed by below normal Mays. One is entitled to be quite flummoxed by this point in the analysis but the conclusion should be that, at least in the most recent years, making a prediction about tornado activity in May, based on the character of the season to date through April, would be a tricky bet.

Last year saw an active start through April only to be followed by a somewhat quiescent May. That situation was addressed in this blog post.

Despite the fact that the correlation coefficient (r) for this entire time series is an abysmal 0.15, there is still hope (albeit diminishing) that we can say something about the predictability of the future based on what has happened in the past. So, one last chart for all of those folks hoping to capture a tornado during the upcoming VORTEX2 field program…


The correlation coefficient on this time series for tornadoes only occurring in Texas, Oklahoma, Kansas and Nebraska is barely improved over the previous comparison for the entire United States. It’s quite possible that charts used to evaluate the stock market would exhibit a similar lack of correlation. And, perhaps it’s fitting to think of this little experiment in the same light by using an oft-quoted line from a typical mutual fund prospectus: “Past performance is no guarantee of future results.”

Stay tuned. We’ll know the answer soon enough.

Toxic Iceland Volcano Plume has Killed Thousands in the Past

Iceland, a nation of 320,000 people, sits on a large volcanic hot spot in the Atlantic's mid-oceanic ridge, and has a history of devastating eruptions.
The worst was the 1783 eruption of the Laki volcano, which spewed a toxic cloud over Europe with devastating consequences. At least 9,000 people, a quarter of the population of Iceland, died, many from the famine caused by the eruption, and many more emigrated. The cloud may have killed more than 20,000 people in eastern England and an estimated 16,000 in France

Don't worry about the giant rock whizzing by Earth!

Newfound Asteroid to Buzz Earth Thursday
By Tariq Malik

A newly discovered asteroid will zip close by Earth Thursday, but poses no threat of crashing into our planet even though it is passing within the orbit of the moon.

NASA/JPL

The orbit of newfound asteroid 2010 GA6 as it flies by Earth on April 8, 2010 at a distance of 223,000 miles, about nine-tenths the distance between Earth and the moon.
A newly discovered asteroid will zip close by Earth Thursday, but poses no threat of crashing into our planet even though it is passing within the orbit of the moon.

The asteroid, called 2010 GA6, is a relatively small space rock about 71 feet wide and was discovered by astronomers with the Catalina Sky Survey in Tucson, Az. The space rock will fly within the orbit of the moon when it passes Earth Thursday at 7:06 p.m. EDT (2306 GMT), but NASA astronomers said not to worry...the planet is safe.

"Fly bys of near-Earth objects within the moon's orbit occur every few weeks," said Don Yeomans of NASA's Near-Earth Object Office at the Jet Propulsion Laboratory in Pasadena, Calif., in a statement.

At the time of its closest pass, asteroid 2010 GA6 will be about 223,000 miles from the Earth. That's about nine-tenths the distance between Earth and the moon [more asteroid photos].

The space rock is not the first asteroid to swing close by Earth this year.

In January, the small asteroid 2010 AL30 passed within 80,000 miles when it zipped by. Other space rocks have flown past Earth at more comfortable distances greater than several hundred thousand miles.

NASA routinely tracks asteroids and comets that may fly near the Earth with a network of telescopes on the ground and in space. The agency's Near-Earth Object Observations program, more commonly known as Spaceguard, is responsible for finding potentially dangerous asteroids and studying their orbits to determine if they pose a risk of hitting the Earth.

NASA's latest space telescope, the Wide-field Infrared Survey Explorer (WISE) launched in December, has been given the task of hunting new asteroids that were previously undetectable because they shine only in the infrared range of the light spectrum.

So far, the WISE telescope has been discovering dozens of previously unknown asteroids every day. Some of those space rocks have been tagged for closer analysis since they may be potentially hazardous to Earth, WISE mission scientists have said

Australian Weather Radar "UFOs"

Bizarre Radar Map or UFO?

NewsCorp Australian Papers



Strange images appearing on radar maps from the Australian Government's Bureau of Meteorology have the Web wondering: What is it?

They are the digital-age equivalent of crop circles -- mysterious patterns appearing on the Australian Bureau of Meteorology's national radar system without any explanation. UFOs, perhaps?

And the random images, described as red stars, rings of fire and white doughnuts, are sending online conspiracy Web sites into meltdown. The anomalies first began on January 15 when an "iced doughnut" appeared over Kalgoorlie in Western Australia.

Satellite imagery showed there was no cloud over the area at the time to explain the unusual phenomenon, but farmers' online comments claimed it was "unusually hot" all day. It was followed by a bizarre red star over Broome on January 22 and a sinister spiral burst over Melbourne described by amateur radar buffs as the Ring Of Fire Fault.

The Bureau, which did not respond to repeated requests for comment, has acknowledged the anomalies on its popular Web site. It has posted a disclaimer above the national loop feed putting the images down to "occasional interference to the radar data."

"If you notice any circular patterns or straight lines originating from the center of the radar location, this is due to occasional interference to the radar data. The Bureau is currently investigating ways to reduce these interferences." the disclaimer said.

Conspiracy Web sites, however, have lit up with dozens of breathless theories behind the strange anomalies from alien involvement, secret military testing to government weather modification. One theory gaining traction online is the belief the U.S. military has expanded its High Frequency Active Auroral Research Program.

Based at a remote research station in Alaska, the HAARP project involves shooting extremely high frequency radar bursts into the upper reaches of the atmosphere to see what happens after particles of the ionosphere are temporarily excited.
