Electric universe: Pyroclastic flow from Sinabung volcanic eruption last month produced string of 'tornados'

Image
Towering twisters of ash spawned by a pyroclastic flow from a volcanic eruption in Indonesia last month.
When Mount Sinabung erupted in North Sumatra, Indonesia early last month, the pyroclastic flows making their way down the mountain left red-hot deposits along its sides.

Incredibly, as the air above the deposits heated and quickly rose, a group of small "tornadoes" formed, twisting their way down the mountainside as well.

The video of the event, captured by Dr. Richard Roscoe of Photovolcanica, is astoundingly surreal. Check it out above for yourself.


Comment: As far as we're aware, this is the first time such a thing has been witnessed, in the modern era at least.

While 'warm air-cold air exchange' and high winds might have something to do with it, we suspect this is evidence that tornadoes (and other air spirals) are electrical phenomena in which the fundamental exchange is electrical discharge between the highly charged pyroclastic cloud (in this case) and a relatively negatively charged surface. That would also explain why we see lightning during volcanic eruptions, as happened at Sinabung in an earlier eruption:

The important question is: why are volcanoes now demonstrating more electrical activity?

Five dolphins strand on Provincetown flats, Massachusetts

Five common dolphins - four adults and a calf - were found stranded this morning on Provincetown low-tide flats in the East End of town.

As of 9:50 a.m., one dolphin is dead but the rest are still live, said RuthAnne Cowing, Provincetown animal control officer.

The tails of three of the dolphins could be seen moving, according to a Times reporter on the scene, where the wind is blowing and it is very cold.

The dolphins stranded off the intersection of Snail Road and Route 6A near the Harbor Hotel.

Rescuers with the Yarmouthport-based International Fund for Animal Welfare arrived at the stranding scene at about 10 a.m.

No further information is available at this time.

Seventeen and a half years. Not a flicker of global warming. The RSS satellite record, the first of the five global-temperature datasets to report its February value, shows a zero trend for an impressive 210 months. Miss Brevis, send a postcard to Mr Gore.

Fish

Deep sea species comprise 95% of world's fish

Mesopelagic fish live between 100 and 1000 metres below the surface.
Fish that live in the mesopelagic zones constitute 95 per cent of the world's fish biomass, marine biologists have found.

Mesopelagic fish live between 100 and 1000 metres below the surface.

The discovery highlights that mesopelagic fish in the earth's oceans constitute 10 to 30 times more biomass than previously thought.

"This very large stock of fish that we have just discovered that holds 95 per cent of all the fish biomass in the world is untouched by fishers," said the researchers.

Scientists have attributed the secret behind their vast population to their capacity to avoid fish nets and prowling eyes of the birds.

Apocalyptic storm front appears over Sydney, Australia

Looming: A large storm cloud covers the Sydney Central Business District on Wednesday

A gigantic storm front moved in over Sydney on Wednesday and residents were quick to upload dramatic pictures of it to the internet.

Huge clouds hundreds of feet high, with some shaped like giant tubes, loomed menacingly over the city during rush hour.

As forecasters warned of heavy rain and flash flooding, Twitter and Facebook became awash with pictures of the looming storm, with one describing the conditions as 'apocalyptic'.

Jason Murray tweeted 'b****y hell' as the storm rolled in. Another wrote: 'Bad time for bike comute home. OK, that's a storm alright.'

Josh Noble thought the clouds reminded him of a certain Hollywood blockbuster.

'It's Independence Day,' he wrote.

Rare tornado hits Mesa, Arizona

Image

A tornado touched down in Mesa over the weekend, something Valley weather experts said is a very rare occurrence for the area.

The National Weather Service in Phoenix confirmed the tornado on Sunday, one day after strong thunderstorms made their way through eastern parts of the Valley.

Debris that included down trees and an empty hot tub tossed over a brick wall confirmed rotating winds consistent with an EF0 strength tornado with speeds up to 85 mph.

"The EF Scale, which became operational on February 1, 2007, is used to assign a tornado a 'rating' based on estimated wind speeds and related damage," explains the NWS website.

While Arizona sees up to 10 tornadoes per year, almost all of them are in the northeastern part of the state.

At least 28,000 seabirds have now died in NE Atlantic due to winter storms

Image
Thousands of seabirds have been wiped out in the winter storms which have also claimed the lives of dolphins and seals found washed up on west country beaches

The winter storms have caused an "unprecedented" wildlife disaster, wiping out thousands of rare seabirds, experts said yesterday.

An estimated 1,600 dead birds have washed up on beaches in Devon, Dorset, Cornwall and West Wales since early last month, the Royal Society for the Protection of Birds reported.

The bodies of a further 1,000 seabirds have been recovered from beaches in the Channel Islands, with more than 20 species, including guillemots, razorbills, puffins and kittiwakes, among the dead.

The RSPB said that a "double whammy" of climate change and winter storms was making it harder for birds to find enough fish to survive. The deaths will have a serious impact on breeding colonies.

At least 28,000 birds have perished across the north eastern Atlantic region, with nearly 22,000 washed up along the French coast, the conservationists said.

Wildfire near Elgin, Arizona despite 24 hours of heavy rainfall

Image
Despite wet conditions following nearly 24 hours of heavy rainfall, a field caught fire near Elgin on Sunday afternoon.

At 12:54 p.m. the Sonoita-Elgin Fire District (SEFD) was called to the northeast corner of Lower Elgin Road and Rochelle.

"It was very actively burning when we arrived," said SEFD Battalion Chief Kevin Venos adding that the wildfire was brought under containment in less than 30 minutes. He said black smoke could be seen due to a pile of junk that had ignited.

While there was no structural damage, the fire spread into a nearby apple orchard. The density of trees prevented firefighters from bringing in emergency vehicles and so the fire had to be fought using hand tools.

The fire, which is still under investigation, was said to be human caused.

Venos said that despite all the rain, most of the local grasses are considered "fine fuels" and do not retain moisture for very long.

Minnesota mystery: What's killing the moose?


Grand Portage - For moose, this year's winter-long deep freeze across the Upper Midwest is truly ideal weather. The large, gangly creatures are adapted to deep snow: Their hollow fur insulates them like fiberglass does in a house. And the prolonged cold helps eradicate pests that prey on moose, like ticks and meningeal worm, or brain worm. Yet moose in Minnesota are dying at an alarming rate, and biologists are perplexed as to why.

In the 1980s, moose numbered about 4,000 in the northwest part of the state; today, there are about 100. In Northeast Minnesota, the population has dropped by half since 2006, to 4,300 from more than 8,800. In 2012, the decline was steep enough - 35 percent - that the state and local Chippewa tribes, which rely on moose meat for subsistence, called off the moose hunt. The mortality rate rebounded slightly this year, but moose continue to die at twice the normal rate to sustain a population. Researchers elsewhere, along the southern edge of moose territory in New Hampshire and Montana, are also beginning to notice declines in the animals' numbers.
