Pressure is building on the north American plate beyond the rocky mountain continental divide. As far north as the Cascadia range in the Pacific Northwest, south east to Yellowstone, then further south east to Georgia, up north to Montreal / New York …
The threat of a new madrid earthquake , in my opinion, goes up ANOTHER notch, with the signs of more activity in the north east, extending along the faults down to Arkansas.

I haver never personally seen a “lightning” storm off a volcano that was THIS intense. Its a first for me.. and I’ve seen a LOT of volcano eruptions.
This makes the earlier video look like nothing! Something strange is going on with this particular eruption at Sakurajima.. its been active for a while, but not like this…

ScienceDaily (Apr. 10, 2011) — University of Utah geophysicists made the first large-scale picture of the electrical conductivity of the gigantic underground plume of hot and partly molten rock that feeds the Yellowstone supervolcano. The image suggests the plume is even bigger than it appears in earlier images made with earthquake waves.
“It’s like comparing ultrasound and MRI in the human body; they are different imaging technologies,” says geophysics Professor Michael Zhdanov, principal author of the new study and an expert on measuring magnetic and electrical fields on Earth’s surface to find oil, gas, minerals and geologic structures underground.
“It’s a totally new and different way of imaging and looking at the volcanic roots of Yellowstone,” says study co-author Robert B. Smith, professor emeritus and research professor of geophysics and a coordinating scientist of the Yellowstone Volcano Observatory.
Here is what happens if you didn’t bail out the banksters:
Feb. 28 (Bloomberg) — Europeans left stranded at airports last year as an Icelandic volcano spewed ash across the continent may soon benefit from the power that seethes beneath the remote north Atlantic island.
Iceland is doing a feasibility study into building a 1,170- kilometer (727-mile) power cable to Scotland to send some of its untapped potential 18 terawatt-hours of geothermal and hydropower — that’s enough for 5 million European homes. The project has the full backing of the government, Industry Minister Katrin Juliusdottir said in an interview.
“Icelanders live with earthquakes and volcanic activity but the benefits are that now we can monetize these powers,” said Valdimar Armann, an economist at Reykjavik-based asset manager GAMMA, who estimates annual clean-energy exports could reach about a tenth of the island’s $12 billion economy.
The island is trying to emerge from Europe’s biggest banking meltdown this century to restyle itself as one of the European Union’s main sources of renewable energy. The power cable, which would be the longest of its kind ever built, would come as the EU strives to reach its target of 20 percent clean energy by 2020. In about 20 years, Iceland’s energy revenue per capita may rival that in Norway, where oil income has made its $540 billion sovereign wealth fund the world’s second-biggest, Armann said.
Scientists in Iceland are warning that another volcano looks set to erupt and threatening to spew-out a pall of dust that would dwarf last year’s event.
Geologists detected the high risk of a new eruption after evaluating an increased swarm of earthquakes around the island’s second largest volcano.
Pall Einarsson, a professor of geophysics at the University of Iceland, says the area around Bárdarbunga is showing signs of increased activity, which provides “good reason to worry”.
He told the country’s national TV station that a low number of seismometer measuring devices in the area is making it more difficult to determine the scale and likely outcome of the current shifts.

Geologen warnen vor Mega-Eruption des Merapi
(Click on images to enlarge.)
800 Grad heiße Schwaden, binnen Sekunden verbrannte Menschen – die lautlosen, rennwagenschnellen Aschewolken des indonesischen Vulkans Merapi sind tödlich. Der größte Ausbruch könnte noch bevorstehen: Unter dem Berg schlummert offenbar ein riesiges Magmareservoir.
Die Ausbrüche des Merapi werden heftiger – und der große Knall steht möglicherweise noch bevor. Seit Tagen spuckt der indonesische Vulkan 800 Grad heiße Aschewolken. An diesem Freitag hat es den bisher heftigsten Ausbruch gegeben: 20 Kilometer weit rasten die Ströme aus Wasserdampf und Vulkanstaub gespenstisch leise bergabwärts. Die sogenannten pyroklastischen Ströme gleiten auf einem Luftkissen mit der Geschwindigkeit eines Rennwagens nahezu lautlos zu Tal – und sind tödlich: Nach wenigen Atemzügen festigt sich die Asche in der Lunge zu Zement, so dass Menschen ersticken. Die Leichen verkohlen, für Untersuchungen müssen die Körper mit Hammer und Meißel geöffnet werden.
Nachts jagen die Ascheströme meist unentdeckt abwärts, nur ein rötliches Glühen verrät manche Wolken – Schlafende bekommen von der Gefahr nichts mit. Einzig eine Warnung vor dem Ausbruch ermöglicht Menschen die Flucht vor den Todeswolken. Deshalb haben indonesische Behörden die Sperrzonen um den Vulkan immer mehr erweitert. Nun sollen alle Anwohner im Umkreis von 20 Kilometern in Flüchtlingslager gehen. Doch viele weigern sich, ihre Häuser zu verlassen.
Schon 122 Menschen sind in den pyroklastischen Strömen ums Leben gekommen, die meisten von ihnen an diesem Freitag.“Die Hitze umgab uns, und überall war weißer Rauch zu sehen”, sagte der 47-jährige Niti Raharjo, der mit seinem 19-jährigen Sohn vor der Gaswolke floh, der Nachrichtenagentur DAPD. “Ich sah Menschen rennen, im Dunkeln schreien, Frauen so verängstigt, dass sie ohnmächtig wurden.”
JAKARTA (Reuters) – Indonesia’s Mount Merapi volcano erupted on Monday for the third time in a week, driving the number of refugees to almost 70,000, as the death toll from a tsunami thousands of kilometers to the west rose to 431, officials said.
The fresh eruption forced a thick ash cloud around 1.5 kilometers (0.9 miles) into the air above Merapi, which sits on the outskirts of Yogyakarta city in Central Java, and caused panicked residents to flee villages on the slopes of the mountain for safety shelters.
The National Disaster Mitigation Agency said that 38 people have been killed and 69,533 evacuated since Merapi began erupting last week, while Indonesia’s vulcanology agency warned that flights around Yogyakarta may be disrupted.
Indonesia’s Anak Krakatau volcano in Sunda Strait, straddling East Java and Sumatra, has spewed ash and flaming rocks.
Officials raised alert levels to ‘high’ on Friday as the volcano showed signs of increased activity, producing 117 small eruptions.
Staff at the observation post in Pasauran, Banten Province are on a 24-hour watch. Residents in Pasauran have been told to stay at least two kilometres away from the volcano.
Anak Krakatau means ‘Child of Krakatau’, named so because it rose in the place of Krakatoa volcano after it blew itself apart in one of the most destructive eruptions in history in 1883. The area is a popular tourist site and many villagers farm on the slopes of nearby Ibu Krakatau (Mother of Krakatau) on the same island.
“Until now we are still on alert level but when we examined our equipment on October 27 and 28 we experienced tremors,” said Anton Priambudi, a volcanologist observing Anak Krakatau.
Several volcanos in Indonesia increased their activities recently following Mount Merapi’s eruption on Tuesday.
The eruptions came only a day after a tsunami struck the remote islands in western Indonesia.

Alert Raised as Anak Krakatau Acts Up
Nov. 2 Jakarta — The Volcanology and Geological Disaster Mitigation Agency on Monday warned the public to avoid the increasingly active Anak Krakatau volcano in the Sunda Strait between Java and Sumatra.
Anton Triambudi, an official from the agency, or PVMBG, said the volcano spewed heat clouds and lava on Monday.
He said people should stay at least two kilometers away from the area to avoid being hit by scorching debris reaching temperatures up to 1,000 degrees Celsius.
Authorities have raised the volcano’s alert level to II, which means there is magma activity that could lead to an eruption.
If the volcanic activity escalates, Anton said the alert level could be raised to III, with IV being the highest.
European Neanderthals may have been wiped out by a catastrophic volcanic eruption over 40,000 years ago, according to new research.
A new study says that a massive explosion caused the onset of a ‘volcanic winter’ that devastated their population.
Researchers led by Liubov Golovanova of Russia’s ANO Laboratory of Prehistory in St. Petersburg report that volcanic dust deposits found in a cave in the Caucasus show that an ecological disaster was responsible.
Very few plants existed in the volcanic dust layers, the researchers discovered.
The loss of plants would have affected the population of large mammals, which were the Neanderthals’ main source of food.
The Neanderthals were replaced about 30,000 years ago by modern-day humans.
Volcano erupts in Indonesia forcing thousands from homes
(Reuters) — A volcano has erupted on the Indonesian island of Sumatra for the first time in four centuries, sending smoke 1,500 metres into the air and prompting the evacation of thousands of residents.
There are no reports of casualties so far, and aviation in the area is unaffected.
Mount Sinabung, in the north of Sumatra, began erupting around midnight after rumbling for several days. Lava was overflowing from its crater, the head of Indonesia’s vulcanology centre told Reuters news agency. The agency has placed the volcano on red alert, its highest level.
2nd Iceland volcano issues warning
LONDON – A second, much larger volcano in Iceland is showing signs that it may be about to erupt, scientists have warned.
Since the start of the Eyjafjallajökull eruption, which caused cancellations of thousands of flights in Europe because of a giant ash cloud, there has been much speculation about neighboring Katla.
An initial research paper by the University College of London Institute for Risk and Disaster Reduction said: “Analysis of the seismic energy released around Katla over the last decade or so is interpreted as providing evidence of a rising … intrusive magma body on the western flank of the volcano.”
“Earlier seismic energy release at Katla is associated with the inflation of the volcano, which indicates it is close to failure, although this does not appear to be linked to seismicity around Eyjafjallajökull,” it added. Continue reading »
The Hekla volcano has had more than 20 major eruptions since the 9th century, and Hekla has had eruptions in 1980, 1991 and 2000.
Many believe that the next Hekla eruption is imminent, and the recent Iceland volcano eruption in Eyjafjallajoekull has added to those fears.
But rumors of a Hekla volcano eruption today are false.
Twitter was filled with Hekla eruption rumors after an MSNBC Twitter feed @BreakingNews tweeted, “Large plume indicates second Icelandic volcano, Hekla, has begun erupting – watch live http://bit.ly/9iNfKE.”
That tweet was retweeted more than 600 times, though the feed later corrected itself.
The BNO News Wire Service also reported the eruption, stating, “REYKJAVIK (BNO NEWS) — The Hekla volcano in southern Iceland has erupted.” Continue reading »
Flying over Eyjafjallajökull, the Icelandic volcano that’s brought Europe’s air travel to a halt, is not for the fainthearted. And there may be worse to come.

The power and wrath of Eyjafjallajökull came into dramatic clarity this weekend as the clouds parted for the first time since the glacier-topped volcano threw world air travel into turmoil.
Fresh eruptions thrust new torrents of molten rock through the shattered ice sheets in the mountain crater, spewing a towering wall of ash, dust and steam high into the air.
I was aboard a small six-seater helicopter carrying the first civilian passengers to approach the scene when coastguard observers operating aircraft high above warned the pilot to be wary of the latest barrage of explosions. Continue reading »

A Cloud of Volcanic Ash Has Led To Airpace Closures All Over Europe
Smoke and steam is seen rising from the volcano under the Eyjafjallajokull glacier in Iceland, which erupted for the second time in less than a month. The eruption melted ice, shot smoke and steam into the air and forced hundreds of people to flee rising floodwaters. (AP)
The potentially dangerous cloud of ash and rock spewed up by the volcano more than 1,000 miles away caused the U.K., Norway, Ireland and Sweden to enforce a nationwide no fly policy, stranding thousands of travelers .
France has also announced some airport closures, and Holland, Belgium, Denmark and Germany are expected to follow suit.
“So we’re talking about almost one quarter of the entire European area is closed to aircraft at the moment.” Brian Flyn of EuroControl, a European aviation authority, told reporters.
It is not yet clear when the flying restrictions will be lifted, but the Eyjafjallajokull volcano is still erupting and could continue spewing ash into the atmosphere for weeks.
“It is likely that the production of ash will continue at a comparable level for some days or weeks,” said Einar Kjartansson, a geophysicist at the Icelandic Meteorological Office. “But where it disrupts travel, that depends on the weather.” Continue reading »
ROME (AFP) – Europe’s largest undersea volcano could disintegrate and unleash a tsunami that would engulf southern Italy “at any time”, a prominent vulcanologist warned in an interview published Monday.
The Marsili volcano, which is bursting with magma, has “fragile walls” that could collapse, Enzo Boschi told the leading daily Corriere della Sera.
“It could even happen tomorrow,” said Boschi, president of the National Institute of Geophysics and Volcanology (INGV).
“Our latest research shows that the volcano is not structurally solid, its walls are fragile, the magma chamber is of sizeable dimensions,” he said. “All that tells us that the volcano is active and could begin erupting at any time.”
The event would result in “a strong tsunami that could strike the coasts of Campania, Calabria and Sicily,” Boschi said.
The undersea Marsili, 3,000 meters (9,800 feet) tall and located some 150 kilometres (90 miles) southwest of Naples, has not erupted since the start of recorded history.
It is 70 kilometres long and 30 kilometres wide, and its crater is some 450 metres below the surface of the Tyrrhenian Sea. Continue reading »
