Ordinary Compasses Thrown Off by Changes in Earth's Magnetic Field

Gary A. Glatzmaier / UCSC A computer simulation shows the Earth's magnetic field lines and two poles, with blue lines directed inward and yellow lines directed outward.

The Earth's magnetic field is changing at an increasing rate, throwing off airports and altering the aurora borealis -- and its effect on ordinary compasses could mean the difference between homeward bound and hopelessly lost.

Earth’s northernmost magnetic point -- or magnetic north -- is distinct from its geographic North Pole, and scientists have long known that the magnetic poles are on the move.

But the magnetic poles have been moving faster lately, sliding towards Siberia at 34 miles per year at a speed that's accelerated 36 percent over the last 10 years, according to the United States Geological Survey, or USGS.

Since compasses rely on magnetic north to point you in the right way up the trail, the average $2-dollar model could very well point you in the wrong direction. Depending on location and journey length, unaware hikers or boaters could find themselves hundreds of miles off course if they don’t calibrate for the shift, experts said.

“At Washington D.C., the compass points 10 degrees to the west of true north," Jeffrey Love, USGS advisor for geomagnetic research, told FoxNews.com. "And this is increasing at Washington at a rate of about 1/10 of a degree per year.”

But don't touch that calibration dial just yet: The accuracy of compasses fluctuates with the field, he said, meaning compasses are more or less accurate depending on where you use them.

“It's different at different places on the earth,” Love said.

The magnetic shift is costing the aviation and marine industries millions of dollars to upgrade navigational systems and charts, Florida's Sun Sentinel reported.

"You could end up a few miles off or a couple hundred miles off, depending how far you're going," Matthew Brock, a technician with Lauderdale Speedometer and Compass, a Fort Lauderdale company that repairs compasses, told the paper.

Luckily for the younger generation, modern GPS technology is able to account and adjust for magnetic north’s deviation, also called magnetic declination. And scientists reassure the general public that the average individual will most likely not be affected at all by the shift in the magnetic field.

But hikers should be aware: The shift adds up to a one-degree difference in compass direction every ten years, Love said.

A spokesman for the National Park Service says cartographers aren’t scrambling to update their maps any time soon.

“We haven’t issued any warnings to hikers, and we don’t really plan to do that,” Jeffrey Olson, a representative for the National Park Service, told FoxNews.com. “Many or most trail guides will provide hikers with the location of the pole, and then they can feed those coordinates into any GIS.” A Geographic Information System is anything that works with location data. “That will help them find their way back.”

There are other effects to the roaming pole as well: Americans will be less likely to see the aurora borealis, for example.

“As the pole of the magnetic field migrates towards Siberia, the latitude that we observe the aurora borealis will increase for America,” Love told FoxNews.com. “It’s easier to see at higher latitudes. The optimal spot right now to see it is Fairbanks, Alaska, but it will slowly move north from there.”

And there have been some inconveniences for the Federal Aviation Administration, too. Airports across the country have repainted their runways so as to be more precise in terms of latitudinal and longitudinal coordinates, and many are planning to adjust in the future.

The polar shift is directly related to the movement of Earth’s magnetic field, which in turn, is related to the movement of Earth’s liquid iron core. The core is in a constant state of convection, or the transfer of heat within fluids. Since the core is convecting, it produces what Love referred to as a “naturally occurring electrical conductor.” And with electric current comes the magnetic field.

Fluctuations in the magnetic field have occurred for hundreds of thousands of years, so the shifting pole doesn’t exactly worry scientists. Sometimes the movement is slow, sometimes fast. The rapidity of the change has to do with the amount of activity going on in the earth’s core. But over time, the axel pole and the magnetic pole eventually equal one another.

“It’s a mathematical construct,” John Tarduno, professor of geophysics at the University of Rochester, told FoxNews.com. “The magnetic field is calculated over the entire planet. So when we think of the pole moving a large amount, we’re really talking about the magnetic field changing on a time scale. It’s true that that pole will wander around the true axis pole. But over thousands of years, the axel pole and magnetic pole will average to be in the same location.”

That's small consolation for someone looking to find their way home with a compass, of course.

Add to the ever evolving nature of Earth’s magnetism the fact that the overall magnetic field has been decreasing as well. Scientists have only been able to measure the intensity of the field since the 1830s, but ever since then, its strength has been on the decline, having decreased by about 10% since it was first measured. But for those concerned with this polar shift -- or even a possible polar reversal -- Love says there is no need to worry in our lifetime.

“Reversals -- which is the changing of the polarity of the magnetic field -- that typically takes about 10,000 years to happen,” Love told FoxNews.com. And “10,000 years ago civilization did not exist. These processes are very slow and therefore, we don’t have anything to worry about.”

First look at new volcano fissure erupting in Hawaii

March 5, 2011 Volcano
http://www.bigislandvideonews.com/2011/ ... in-hawaii/

Afbeelding
Video courtesy Hawaiian Volcano Observatory

The geologists with the USGS Hawaiian Volcano Observatory have released a first look at the new fissure eruption that just started today between Pu`u `O`o and Napau Crater.

According to geologists, the first portion of the video was shot from the air looking southwest at the fissure eruption between Pu`u `O`o and Napau Crater. The fissure segment in the tephra in the foreground opened seconds earlier, and only about 10 minutes after the eruption as a whole started. The cracks through the tephra are in the process of opening, though this can’t be picked out at this distance.

The second part of the video was shot from the ground in front of the propagating fissure, showing low spattering that started moments earlier. Thick white steam from the crack in the foreground indicates that lava is about to reach the surface, and is seen doing so seconds later.

Lastly, we see an image of spattering near the front of the propagating fissure.

Meanwhile, the current Volcano Alert Level for Kilauea on Hawaii Island has been upgraded from Watch to Warning, and the current aviation color code has been upgraded from “orange” to “red”.

Planets and Earthquakes

TUESDAY FEBRUARY 22, 2011
http://www.predictweather.com/ArticleSh ... &type=home


The planets very much affect the earth, indirectly, by having an effect on the Sun. Some planets are very large. If the Sun was a basketball the gas giants Jupiter and Saturn would be the size of grapeftuits, and the Earth would be, on that scale, the size of a peppercorn.

Jupiter and Saturn cause extra tides on the Sun when they get on either side of the Sun (as with Moon - Earth-Sun when the moon is full) and when these gas giants get on the same side as the Sun, (as with Earth -Moon - Sun when the moon is new). These greater solar tides become sunspot activity and solar flares and can be understood as akin to the increase in tides caused by the Moon when it too gets alongside Earth or opposite Earth.

At the moment we have Jupiter and Saturn on either side of the Sun and creating a tug of war with Earth in the middle. That started last September

Afbeelding

and will continue until about May. In September the Earth was right in line with Jupiter, Saturn and the Sun too. That's why there were several 7+ earthquakes around, it wasn't just us. For instance there was one in Pakistan on the same day as Christchurch. This Jupiter/Saturn alignment continues until about May, and the Earth comes back into line as well in March. It is why there may be an extreme event, perhaps a large earthquake, around 20 March, which is when the Moon may be again in a trigger position.

Afbeelding

By the time May comes, Earth will have somewhat moved away from this alignment

Afbeelding

and by the time November comes, Jupter/Saturn have moved away.


But for now, the moon moves closer until it is the closest in March. For now there are many solar flares. Over the past 2 days there have been over 100 sunspots per day. They take one or two days to reach Earth. The Sun is the producer, the flares are the driver and the engine, and the Moon is the director, does the steering and acts as trigger.

After April the Moon doesn't come close again till September and October and so we can expect some extreme weather then too. 2020 is the next danger time from the positioning of Jupiter and Saturn.

The question that arises is what happened the last time that Jupiter and Saturn were in the same position, when it matched now. That date was February 1990. The earth was again in the middle for a week or two. Perhaps unsurprisingly, a 6-mag occurred in North Canterbury near Lake Tennyson on full moon day on 10 Feb 1990

Afbeelding

This shows that such events are not new to Christchurch, whereas our increased awareness of them is. It also shows that certain planets are responsible for having effects on the Sun and therefore the Earth, as the Sun directly affects Earth through varying degrees of solar radiation. Solar radiation ionises the air to create storms and electromagnetism affects gravity and from there the tides of inner core, land, sea and air.

It therefore means the old astrologers were probably right in that the planets can have an effect changes down here, indirectly through affecting events on the Sun. What the reader may have read about astrology is often a beat-up, perhaps because it is still practised in other cultures, which makes it suspicious. But it is really science, not pseudoscience, and very much of interest to organisations like the NASA Goddard instute.

Indonesië getroffen door natuurgeweld

Uitgegeven: 11 maart 2011 13:37
Laatst gewijzigd: 11 maart 2011 14:10

http://www.nu.nl/buitenland/2465972/ind ... eweld.html

AMSTERDAM - Indonesië is vrijdag getroffen door overstromingen en een vulkaanuitbarsting. Bovendien maken duizenden Indonesiërs zich op voor een tsunami die hun kant op komt.

In het westen van Indonesië, in de provincie Atjeh, kwamen donderdagnacht ten minste twaalf mensen om het leven bij plotselinge overstromingen.

De overstromingen waren het gevolg van zware slagregens waardoor een rivier buiten zijn oevers trad.

Meer dan honderdvijftig huizen werden door het water verwoest. De verwachting is dat het dodental nog zal toenemen, omdat er nog veel mensen worden vermist.

Vulkaan

Op het eiland Sulawesi kwam vrijdag de Karangetang-vulkaan tot uitbarsting. De vulkaan braakte lava en gloeiendhete gaswolken uit.

De autoriteiten proberen uit alle macht om mensen die aan de voet van de vulkaan wonen te evacueren. Vorig jaar augustus barstte de vulkaan ook al uit; vier mensen verloren toen het leven.

Tsunami

Ondertussen is het oosten van Indonesië getroffen door een kleine tsunami, die geen schade heeft veroorzaakt. Dat meldde de meteorologische dienst.

De Indonesische regering waarschuwde eerder dat de tsunami, die veroorzaakt is door een zeebeving bij Japan, mogelijk twee meter hoog zou zijn.

Voor bijna achttienhonderd kilometer kustlijn - van Noord-Sulawesi tot Papoea - is een waarschuwing van kracht.

Heavy snowfall halts daily life in Turkey and Greece

Friday, 11th March 2011
http://www.timesofmalta.com/articles/vi ... and-greece

Afbeelding


A cold wave that hit Turkey and Greece this week has brought heavy snowfalls that paralysed traffic and shut schools in both capitals and disrupted road and air travel in other cities.

Ankara was buried in 50 centimetres of snow which fell for a third day yesterday, snarling traffic despite a major clearance operation. Anthens was also covered in snow on Wednesday.

Schools were closed and residents had difficulty making the journey to work with road and rail links between both capitals and several nearby towns cut off.

The snowfall in Ankara was the heaviest for 10 years, meteorologists said, quoted by TV channels. In at least five more cities, schools were closed due to heavy snowfalls.

Some flights were delayed but none were cancelled at Ankara Esenboga Airport, officials told Anatolia news agency, although a number of flights from Istanbul to other domestic cities and abroad were cancelled.

Major roads in downtown Istanbul remained open, although some side-streets on the Asian side of the city were closed down due to snow and high winds forced the cancellation of some ferry services. City officials said about 3,000 employees worked non-stop to keep the traffic flowing in Istanbul, with a population of more than 12 million people. Roads to hundreds of villages around Turkey were also blocked due to snow.

Two fishermen have been missing since Tuesday due to storms on Lake Manyas in northwestern Turkey, an official from Balikesir province told to news channel NTV. Izmir and Antalya, two major cities of Turkey, known for their warm climate, are also affected by snowfalls.

Aardbeving Japan gevolg van supermaan?

11/03/11, 18u05
http://www.demorgen.be/dm/nl/9757/Aardb ... maan.dhtml

Over acht dagen komt de maan zo dicht bij de Aarde, dat door sommigen gevreesd wordt dat de aantrekkingskracht van de maan chaos zal brengen op Aarde. De afstand tussen de twee hemellichamen zal dan minder dan 366.000 kilometer bedragen, iets wat niet meer gebeurd is sinds 1992. Doemdenkers voorspellen rampen, zoals vulkaanuitbarstingen en aardbevingen, als gevolg van deze 'supermaan'. Met de zware aardbeving in Japan en de bijhorende tsunami wordt de vraag gesteld: is de 'supermaan' hiervoor verantwoordelijk?
Het lijkt een vergezochte verklaring: de supermaan is nog 8 dagen ver weg en de claims van chaos en vernieling zijn verwachtingen, geen zekerheden. Maar believers argumenteren dat de maan al dicht genoeg is om zijn krachten te laten gelden.

"Supermanen zijn doorheen de geschiedenis gelinkt aan sterke stormen, hoge waterschanden en zelfs springtij en ook aardbevingen", aldus astroloog Richard Nolle, die de term 'supermaan' bedacht in 1979.

Geen dagelijks effect
Wetenschappers staan niet aan zijn kant. "Als de maan echt grote aardbevingen zou uitlokken, dan zou het op dagelijkse basis massa's kleine aardbevingen moeten uitlokken. Dat is niet zo, dus de maan heeft geen effect", argumenteert seismoloog George Helffrich.

Enkel mooi fotomoment
"De supermaan is enkel een mooi fotomoment voor astronomen, maar zal geen impact hebben op de Aarde. De maan komt enkele kilometers dichterbij dan normaal tijdens het perigeum, maar een significant verschil kan je dat niet noemen", aldus ruimtegeschiedkundige David Harland.

Dichtbij + volle maan
Het perigeum is het punt in een baan rond de Aarde dat het dichtst bij het zwaartepunt van de Aarde ligt. Op dat punt beweegt het hemellichaam zich het snelst. Dit gebeurt een keer per maandcyclus. Volgende week valt het perigeum samen met een volle maan, wat maar een keer om de twee of drie jaar gebeurt.

Maar de believers houden voet bij stuk. "Supermanen zijn zoals eclipsen: er zijn er vijf of zes per jaar. Maar het is niet enkel op het dichtste punt dat ze een merkbaar effect uitoefenen", verdedigt Nolle zijn idee. (edp)

Dagen voortaan ietsje korter
14-03-11
http://www.waarmaarraar.nl/pages/re/611 ... orter.html

De aardbeving in Japan heeft de dag iets korter gemaakt. De beving heeft de draaiing van de aarde vrijdag met 1,6 microseconden versneld. De as van de aarde is 15 centimeter verschoven. Expert Richard Gross van de Amerikaanse ruimtevaartorganisatie NASA heeft dat berekend.

De versnelling was iets meer dan het effect van de aardbeving in Chili vorig jaar. Het meeste effect was er bij de beving in het Indonesische Sumatra in 2004. Toen duurde de dag 6,8 microseconden korter. Voor de duidelijkheid : Een microseconde is een miljoenste seconde.

China floods: Millions affected by deadly downpours
19 June 2011 Last updated at 13:41 GMT
http://www.bbc.co.uk/news/world-asia-pacific-13831068

More than two million people are now reported to have been affected by deadly floods in eastern China.

Torrential rain was continuing, leaving large parts of Zhejiang and Hubei provinces under water, state-run news agency Xinhua said.

It said nearly 1,000 businesses were being disrupted and crops destroyed, pushing up food prices.

This month's flooding - the worst since 1955 - has already left about 170 people dead or missing, reports say.

The government has mobilised troops to evacuate hundreds of thousands of people.

China's disaster alert has been raised to the highest level, four.

Downpours earlier this week triggered landslides that buried houses and killed at least two people in Zhejiang and another two in Hubei.

The floods come after months of crop-destroying drought in the centre and north of the country.

Some areas along the Yangtze River have suffered their worst drought in half a century.

Despite the rain, officials have warned that the crop shortages and dislocation caused by drought will remain severe.

Analysts say crop shortages in China could affect prices around the world.

Shock as retreat of Arctic sea ice releases deadly greenhouse gas

Russian research team astonished after finding 'fountains' of methane bubbling to surface
Afbeelding
Dramatic and unprecedented plumes of methane – a greenhouse gas 20 times more potent than carbon dioxide – have been seen bubbling to the surface of the Arctic Ocean by scientists undertaking an extensive survey of the region.

The scale and volume of the methane release has astonished the head of the Russian research team who has been surveying the seabed of the East Siberian Arctic Shelf off northern Russia for nearly 20 years.

In an exclusive interview with The Independent, Igor Semiletov, of the Far Eastern branch of the Russian Academy of Sciences, said that he has never before witnessed the scale and force of the methane being released from beneath the Arctic seabed.

"Earlier we found torch-like structures like this but they were only tens of metres in diameter. This is the first time that we've found continuous, powerful and impressive seeping structures, more than 1,000 metres in diameter. It's amazing," Dr Semiletov said. "I was most impressed by the sheer scale and high density of the plumes. Over a relatively small area we found more than 100, but over a wider area there should be thousands of them."

Scientists estimate that there are hundreds of millions of tonnes of methane gas locked away beneath the Arctic permafrost, which extends from the mainland into the seabed of the relatively shallow sea of the East Siberian Arctic Shelf. One of the greatest fears is that with the disappearance of the Arctic sea-ice in summer, and rapidly rising temperatures across the entire region, which are already melting the Siberian permafrost, the trapped methane could be suddenly released into the atmosphere leading to rapid and severe climate change.

67 Tornadoes Decimate Midwest, Extreme damage


LOUISVILLE, A spokesman for Kentucky's governor says that five people have died in severe weather in that state, bringing the death toll from Friday's storms around the country to at least 13 people.
Terry Sebastian, a spokesman for Gov. Steve Beshear, says the people were killed in two different counties as the state was raked by a tornado-spawning weather system.

At least eight people died Friday in Indiana where tornadoes pummeled small towns in the southern part of the state.
The band of powerful storms stretching from the Gulf Coast to the Great Lakes is the second deadly tornado outbreak this week.
UNDATED - Indiana authorities say at least three people have been killed by tornadoes that struck the southern portion of the state.

Officials say houses are missing near the small town of Chelsea, Ky. And the National Weather Service says there has been "extreme damage" in Henryville, a town of about 1,000 people just north of the Kentucky border. A law enforcement official also says the town of Marysville is "completely gone."

Just to the east, in Kentucky, an apparent tornado flattened a volunteer fire station. Dozens of homes were damaged in Alabama and Tennessee.
The violent weather struck two days after storms killed 13 people in the Midwest and South.
In the Chattanooga, Tenn., area, at least 20 homes were badly damaged and six people were hospitalized after strong winds and hail lashed the area.

Power grid goes down for millions of Americans as Mother Nature reminds us all to get prepared

by Mike Adams, NaturalNews.com, June 30, 2012

http://www.naturalnews.com/036354_power ... _wave.html

(NaturalNews) Mother Nature has a way of interrupting our lives with not-so-subtle reminders to pay attention to reality. Over the last 48 hours, a blistering heat wave has swept across nine U.S. states, causing the power grid to fail for millions of residents. Virginia Governor Bob McDonnell has declared a state of emergency.

“Millions of people across nine states were reeling without power Saturday to deal with thermostat-popping temperatures after fierce thunderstorms pounded parts of the Midwest and Atlantic Seaboard,” reports CNN (www.cnn.com/2012/06/30/us/extreme-heat/index.html).

“In storm-affected areas, many people had no electricity to run fans, air-conditioning and refrigerators. Even in places where power was not disrupted, people with no air-conditioning were advised to spend the day in a library or a cooling center to avoid heat exhaustion.”

At the same time, a crushing, violent storm swept through Washington D.C., killing at least 10 more people and bringing down the power grid to millions more. “More than 3 million are without power — and without air conditioning — as crews work to clear downed tree limbs and restore electricity,” reports CBS News. (washington.cbslocal.com/2012/06/30/eastern-u-s-storms-leave-5-…)

“Power outages were reported from Indiana to New Jersey, with the bulk of the service interruptions concentrated in the Mid-Atlantic region. Earlier Friday, the nation’s capital reached 104 degrees — topping a record of 101 set in 1934.”
