Major Earthquakes Strike Near North And South Poles ; Geomagnetic Reversal Signs Evident Across The Globe
Major earthquakes strike near north and south poles
From increased ice melt reported from the Greenland Ice sheet to the sublimation of methyl hydrates near Spitsbergen, to an increased number of swarms and large earthquakes; the dynamics of the Arctic Circle is quickly and ominously morphing.
August 30, 2012 – ARCTIC CIRCLE – A powerful 6.8 magnitude earthquake erupted in the Jan Mayen Island region of the Arctic Circle, north of Iceland. The earthquake had a depth of 9.9 km (6.2 miles) and was followed by a 5.2 magnitude aftershock. Seismic turbulence has been increasing in the Arctic Circle in the month of August, as seen from the map above. On August 14, a – 7.7 magnitude earthquake struck in the Sea of Okhotsk near NE Russia. Today’s 6.8 magnitude Arctic earthquake was preceded by double moderate tremors along the Western Indian-Antarctica Ridge in the 5.4 and 5.0 range. The seismic dynamism that has the planet reeling, from pole to pole, increases the potential for major seismic disturbances along the Nazca plate of South America, the Cocos plate, along Central America; and, or the SW region of the U.S. near the Gulf of California, where the Pacific and North American plate are experiencing increased agitation.
Record melt of Arctic sea ice: “It’s hard even for people like me to believe, to see that climate change is actually doing what our worst fears dictated,” said Jennifer A. Francis, a Rutgers University scientist who studies the effect of sea ice on weather patterns. Scientific forecasts based on computer modeling have long suggested that a time will come when the Arctic will be completely free of ice in the summer, perhaps by the middle of the century. This year’s prodigious melting is lending credibility to more pessimistic analyses that it may come much sooner, perhaps by the end of the decade. “It’s an example of how uncertainty is not our friend when it comes to climate-change risk,” said Michael E. Mann, a climate scientist at Pennsylvania State University. “In this case, the models were almost certainly too conservative in the changes they were projecting, probably because of important missing physics.” –Anchorage Daily News
Precursors to a Magnetic Shift: Earthquakes, Volcanoes, and Extreme Weather
By Mitch Battros – Earth Changes Media
Aug 29, 2012 – 2:49:54 AM
Most of this research is spoken in “scientificeese” so I will do my best to make it understandable to most. What is transpiring is the awakening of a new science era. With new space instruments of crafts and satellites – along with new geological drilling of oceans floors which includes new instrumentation to observer Earth’s outer core, mantle, lithosphere, and crust – an encompassed multi-disciplinary reservoir of data has brought forth the most competent consummation of the Sun-Earth connection.
What we are witnessing is the precursor’s in-motion of a very natural event the Earth has seen many times before. Ancient text suggests several of our ancestral tribes knew of these cycles-of-events, and tried their best to convey such wisdom through the language of their time. Some would say they went far beyond their ‘in-time’ ability to communicate, and used symbols, math, and science to tell their story.
Well finally, we may have grown enough as a culture (scientifically speaking) to comprehend what has been known for millennia. Unfortunately, one might suggest we as a culture have fallen way short of our innate human-sensory evolution. Our thwarted sense of who we are – and dimmed recognition of our generational genetic history has been all but lost. But I am eternally hopeful this could change and change fast.
Perhaps the consolidation of ancient wisdom – described in ancient books and symbols all of which point to this moment-in-time of which describes a time of “transition”. There is one other uniformed description which appears universally among all tribes: “It will come from the sky”.
Now for a bit of ‘scientificeese’
I will come forward and say, the recent earthquake swarm in So. California now numbering over 300 and is expected to continue for several days, is a consequence of the Earth’s shifting outer core, mantle, lithosphere, and crust. Furthermore, I would say Sunday’s 7.4 quake off the coast of El Salvador is also connected. And perhaps the most extreme supposition I will make, is the four current hurricanes Isaac, Ileana, Bolaven, and Tembin are all related to the current in-action precursor’s to a full magnetic shift.
The Science Behind My Claim
In the science community it is called the study of ‘Margins’, sometimes referred to as boundaries. Plate margins is the area where two or more continental or oceanic plates meet. There are four types of plate margins; destructive, constructive, collision, and conservative. The type most vulnerable to magnetic shifts are the destructive and constructive.
Ongoing studies supported by the NSF (National Science Foundation) indicate a connection between submarine troughs (rifts), Earth’s mantle, and Earth’s outer core. Furthermore, new research indicates the shifting of magnetic flux via Earth’s magnetic field, has a direct and symbiotic relationship to Earth’s outer core, mantle, lithosphere, and crust.
As a living entity, Earth fights for its survival. If internal or external events begin to throw Earth out of balance i.e. orbital, tilt, or magnetic alignment – it begins to correct itself. When oceanic tectonic subductions occur, it cools the mantle and outer core. To balance this shift in temperatures, the Earth’s core increases heat and as a result released what is known as “mantle plumes”. These plumes filled with super-heated liquid rock float up to the ocean bottom surface.
This action both cools the outer core and heats the oceans. As a result of heated oceans, we get tropical storms and various forms of extreme weather. When troughs, subduction zones, and rifts shift, as a result of convection, earthquakes, tsunamis, and volcanoes occur.
What makes this all work is the Earth’s magnetic field. Right now the magnetic field is weakening significantly. This will continue until it reaches zero point, at which time there will be a full magnetic reversal. Until this time, we will witness magnetic north bouncing in the northern hemisphere. Closer to the moments of a full reversal, we will see magnetic north drop down to/then below the equator.
As a result of a weakened magnetic field, larger amounts of radiation via charged particles such as solar flares, coronal mass ejections, gamma rays, and galactic cosmic rays – are more abundantly reaching Earth’s atmosphere and having a heightened reaction with Earth’s core layers. This is what causes looped reaction. Radiation heats the core layers, the outer core reacts by producing ‘mantle plumes’, which causes crustal fracturing, which then causes earthquakes, volcanoes, heated oceans – all of which cools the outer core.
This seemingly repeating loop will continue until the Earth will once again find its balance. Until then, we can expect naturally occurring earth changing events which will produce the loss of mass in some parts of the world, and emergence of mass in other parts. Maybe this is the time to change the things we can (attitude, environment, community, self, surroundings), one would be a fool not to apply themselves within their means – but then there is the time to loosen up a bit, know what is happening is just part of a process.
Just as the Earth, we humans can just keep on trucking, and maybe, just maybe, some will simply ‘enjoy-the-ride’.

6.6 magnitude earthquake strikes off Greenland’s coast
Published: 30 August, 2012, 18:00
A 6.6 magnitude earthquake was detected off the eastern coast of Greenland, the US Geological Survey reported. No damage or injuries were reported.
The epicenter was recorded at a depth of 8.6 kilometers in the Norwegian Sea, some 93 kilometers northwest of the town of Olonkinbyen on the Norwegian island of Jan Mayen.
The island has no permanent population. A research station is located there, which was housing about 50 people when the quake occurred. The station’s workers are all involved in research and maintenance at the facility, Erik Persheim, an electronics engineer at the station, told the AP. The station normally houses about 18 engineers and other personnel, he said.
The European-Mediterranean Seismological Centre and the USGS said the quake was followed by a 5.2 magnitude aftershock eight minutes later.
“We watched the mountain as the loose stones and shale came sliding down,” Persheim said. “It didn’t seem very big and I don’t think much of anything broke, but we’ll have to have a thorough inspection.”
However, the earthquake, which was considered strong for the region, was not felt by anyone. The city closest to the quake is Akureyri, Iceland, with a population of around 17,500, located 709 kilometers (441 miles) southwest of the epicenter.
The quake struck northeast of Reykjavik, Iceland, where the USGS earlier recorded a 4.8 magnitude tremor.
The tremor was the strongest in the region since the previous record-setter: A 6.2 magnitude quake off the cost of the Svalbard Islands in 2008.
Southern California town declares state of emergency over quake swarm
August 30, 2012 – CALIFORNIA – The southern California town of Brawley has taken the unusual step of declaring a state of emergency after a swarm of earthquakes rattled nearly 20 mobile homes off their blocks and forced a slaughterhouse to close, the mayor said on Wednesday. It is uncommon for quake-hardy California cities to declare emergencies due to tremors, but Brawley mayor George Nava said the earthquake swarm is a unique case because it has lasted for days and caused millions of dollars in damage. The cluster of relatively small quakes, which are caused by water and other fluids moving around in the Earth’s crust, began on Saturday evening and climaxed the next day with a 5.5 temblor, according to the U.S. Geological Survey. The tremors were continuing on Wednesday and geologists say there have been hundreds in total. Nava said leaders in Brawley, a city of 25,000 residents south of the state’s inland Salton Sea and 170 miles (275 km) southeast of Los Angeles, declared a local emergency late on Tuesday. Officials with surrounding Imperial County made a similar declaration on Wednesday. Nineteen mobile homes were knocked off their blocks and their residents forced out, Nava said. The auditorium at Brawley Union High School has been damaged and closed off, and the National Beef slaughter plant in Brawley has been temporarily shut down due to damage, he said. Local businesses have suffered millions of dollars in losses from closures and from customers staying away, Nava said. But he could not give an exact account of quake-related losses. The Red Cross and local government agencies will offer services to residents on Friday and Saturday at a local center. The emergency declaration allows Brawley to receive more assistance from Imperial County, Nava said. At one point, about 10,000 residents in the city were without power, and the quakes have also caused water line disruptions, Nava said. “When you don’t have an AC or running water, it’s just not a good thing in this weather,” he said. Jeanne Hardebeck, research seismologist for the U.S. Geological Survey, said earlier this week that the cluster of quakes is not a sign that a larger temblor is imminent.
4.1 magnitude earthquake strikes Los Angeles region
August 30, 2012 – CALIFORNIA – The 4.1 earthquake that jolted Yorba Linda on Wednesday afternoon appears to be an aftershock of the cluster of quakes that hit the region earlier this month, seismologists said. The jolted area included southeastern Los Angeles County, Orange County and the Inland Empire. The quake occurred in about the same location of an earthquake doublet, two 4.5 quakes that occurred on Aug. 7 at 11:23 p.m. and Aug. 8 at 9:33 a.m. The area was also hit by a 4.0 quake on June 14. Wednesday’s quake, which hit at 1:31 p.m., was located near the center point of the magnitude-5.5 Chino Hills earthquake that reverberated through the Los Angeles Basin in the summer of 2008, U.S. Geological Survey seismologist Lucy Jones told The Times. Wednesday’s quake appeared to be located in the “Yorba Linda trend,” a seismic area identified by Caltech geophysicist Egill Hauksson in 1990, that might be a buried fault. Many who felt the quake said it was relatively mild. At Vinjon’s Kennel in Yorba Linda, the quake hit just as Carisa Feeney, 22, was giving a bath to a year-and-a-half-old boxer mix. When the quake delivered its single strong jolt, the dog leaped up in the tub –- and both quickly ran outside. “I’m pretty much covered in water,” Feeney said. Nancy Ferguson, who owns SGO Designer Glass in Old Town Yorba Linda, said, “We had a big jolt, just for a few seconds, then everything just kind of swayed.” Ferguson, who has hundreds of pieces of glass on display in her store, said she holds her breath every time there’s an earthquake. “But nothing fell over today, so we’re feeling pretty lucky,” she said. It is unlikely that the earthquake swarm that has hit Imperial County with hundreds of quakes since the weekend is related to Wednesday’s quake in Yorba Linda, Jones said.
Jangled nerves in California, as scientist at a loss to explain present Southern California quake swarm
August 29, 2012 – CALIFORNIA – An unusual swarm of hundreds of mostly small earthquakes has struck Southern California over the last three days and shaken the nerves of quake-hardy residents, but scientists say the cluster is not a sign a larger temblor is imminent. The earthquakes, the largest of which measured magnitude 5.5, began on Saturday evening and have been centered near the town of Brawley close to the state’s inland Salton Sea, said Jeanne Hardebeck, research seismologist for the U.S. Geological Survey. Scientists were monitoring the earthquake cluster, which continued on Tuesday, to see if it approaches the Imperial Fault, about three miles away. A destructive and deadly earthquake of magnitude 7.0 struck on that fault in 1940, she said. “We don’t have any reason to believe that the (earthquake) storm is going to trigger on the Imperial Fault, but there’s a minute possibility that it could,” Hardebeck said, adding that the swarm of quakes was not moving closer to that fault. The Brawley quake cluster, which is caused by hot fluid moving around in the Earth’s crust, is different than a typical earthquake, in which two blocks of earth slip past each other along a tectonic fault line. After that kind of an earthquake of magnitude 5.5 or above, there is a 5 percent chance a larger quake will follow, Hardebeck said. But she added the same kinds of probability estimates were not possible with earthquake clusters caused by the movement of hot fluid. “We understand them even less than we understand normal earthquakes,” Hardebeck said, adding that scientists do not know why a cluster of earthquakes will occur at one time rather than another. The swarm led to jangled nerves in Brawley, a town of about 25,000 residents 170 miles southeast of Los Angeles near the border with Mexico. “It’s pretty bad. We had to evacuate the hotel just for safety,” Rowena Rapoza, office manager of a local Best Western Hotel, said on Sunday. There were two earthquakes on Sunday afternoon, one with a 5.5 magnitude and one measuring 5.3, Hardebeck said. Those were the largest quakes in the cluster amid hundreds of others, she said. In the past, earthquake clusters have gone on for as long as two weeks, Hardebeck said. Before this recent cluster in Brawley, the last swarm of this size to hit the area was in 1981, she said.
Geothermal Region: Gulf of California Rift Zone
The Gulf of California rift zone is a complex transition zone between the dextral (right-lateral) motions of the San Andreas transform fault system and the northwestward progressing spreading ridge complex of the Gulf of California segment of the Eastern Pacific Rise. The Gulf of California and its onshore extension, the Salton Trough (which includes Mexicali, Imperial, and Coachella Valleys), are located over a series of rifts in the Earth’s crust which are filling with sediment from above, chiefly from the Colorado River, and magmatic material from below. The Cerro Prieto geothermal field in Mexico and the Brawley Seismic zone in the U.S. are located above two of these rifts, and young volcanoes in these locations are evidence of intrusion of magma from below. The volcanics in this exploration region are less then 5-million year old and associated with northwest folding, block- and thrust- faulting. Dacite is the most common volcanic rock, with a composition that ranges from basalt to rhyolite. The volcanic activity appears to be related to extension associated with the San Andreas Fault system. The most recent volcanic activity is dated to 10,000 years ago. The heat source for the Geysers geothermal field is provided by a silicic magama chamber. Clear Lake Volcanic Field, California. -GE
Ancient tectonic plate slid under Western North America, thining the crust: The Farallon Plate was an ancient oceanic plate, which began subducting under the west coast of the North American Plate— then located in modern Utah— as Pangaea broke apart during the Jurassic Period. It is named for the Farallon Islands which are located just west of San Francisco, California. Over time the central part of the Farallon Plate was completely subducted under the southwestern part of the North American Plate. The remains of the Farallon Plate are the Juan de Fuca, Explorer and Gorda Plates, subducting under the northern part of the North American Plate; the Cocos Plate subducting under Central America; and the Nazca Plate subducting under the South American Plate. The Farallon Plate is also responsible for transporting old island arcs and various fragments of continental crustal material rifted off from other distant plates and accreting them to the North American Plate. These fragments from elsewhere are called terranes (sometimes, ‘exotic’ terranes). Much of western North America is composed of these accreted terranes.

California shaken by dozens of quakes, some reach highest magnitude in decades
Edited: 28 August, 2012, 12:25
More than 70 earthquakes and hundreds of temblors shook Southern California on Sunday and Monday, reaching a 5.5 magnitude range – the strongest the region has seen in three decades.The last time quake swarms shook Imperial County at such a magnitude was in 1981. The region, which borderlines Mexico and is in the Brawley Seismic Zone, is known to produce 6.0 magnitude earthquakes every few decades.
At least 25 aftershocks struck the same epicenter on Sunday, and shaking could be felt up to 120 miles away. Scientists predict that jolts will be felt for several more days.
The series of earthquakes shattered windows and knocked 20 trailer homes off their foundations. A red-tile roof also collapsed and landed on a wooden fence, Maria Peinado, spokeswoman for the Imperial County Emergency Operations, told the Associated Press.
Power outages darkened Southern California buildings, prompting one hospital to evacuate 49 patients. Several gas leaks and water line breaks were also reported. A motel reported a TV crashing down and broken light fixtures.
“It’s not uncommon for us to have earthquakes out here, but at this frequency and at this magnitude it’s fairly unusual,” Brawley town mayor George Nava told AP.
“It felt like there was a quake every 15 minutes. One after another. My kids are small and they’re scared and don’t want to come back inside,” said Brawley resident Mike Patel.
Schools in Brawley stayed closed on Monday as the town continued to feel shaking.
“We’re so anxious right now we can’t sit still,” Brawley resident Alfonso Alvarez told the Lost Angeles Times.
Scientists are studying the swarm to see what impact it had on the fault. Thomas Jordan, director of the Southern California Earthquake Center, said he is concerned about the seismic activity “because that means there is a higher probability of having more seismic activity.”
No deaths or critical injuries were reported, but afflicted Southern California cities are shaken up as they wait for the jolts to stop.
A recent study by Oregon State University estimated a 50 percent chance that a major earthquake will strike southern Oregon near its border with California during the next half-century. Scientists predict that the quake’s magnitude cloud be on par with the tremor that caused the disaster last year in Fukushima, Japan.
Earlier, a comprehensive study by the US Geological Survey determined a more than 99 percent chance of there being one or more magnitude 6.7 or larger earthquakes in California over the next 30 years. There is also a 46 percent likelihood of at least one even more powerful quake in the region in the next 30 years of magnitude 7.5 or greater. Such a quake is most likely to occur in the southern half of California, the report said.
Hot Spots Pinpointed as Earthquake Trigger Points: Small Droplets of Friction-Generated Melts Can Lead to ‘Megaquakes’
By Science Daily
Aug 29, 2012 – 4:14:00 PM
Scientists at Scripps Institution of Oceanography at UC San Diego have come a step closer to deciphering some of the basic mysteries and mechanisms behind earthquakes and how average-sized earthquakes may evolve into massive earthquakes.
In a paper published in the Aug. 30 issue of the journal Nature, Scripps scientists Kevin Brown and Yuri Fialko describe new information gleaned from laboratory experiments mimicking earthquake processes. The researchers discovered how fault zones weaken in select locations shortly after a fault reaches an earthquake tipping point.
They coined such locations as “melt welts” and describe the mechanism akin to an ice skater’s blade reducing friction by melting the ice surface. The mechanism may be similar to “hot spots” known in automobile brake-clutch components.
“Melt welts appear to be working as part of a complicated feedback mechanism where complex dynamic weakening processes become further concentrated into initially highly stressed regions of a fault,” said Brown, first author of the study and a professor in the Geosciences Research Division at Scripps. “The process allows highly stressed areas to rapidly break down, acting like the weakest links in the chain. Even initially stable regions of a fault can experience runaway slip by this process if they are pushed at velocities above a key tipping point.”
“This adds to the fundamental understanding of the earthquake process because it really addresses the question of how these ruptures become energetic and dynamic and run away for long distances,” said Fialko, a paper coauthor and a professor in the Cecil H. and Ida M. Green Institute of Geophysics and Planetary Physics at Scripps.
The study’s results, supported by funding from the National Science Foundation, appear to help answer a longstanding paradox in seismology. Key fault zones such as the San Andreas Fault produce far too little heat from friction compared with the size and magnitude of the earthquakes they produce. Laboratory experiments show that thermal energy normally released by friction during slip can become rapidly reduced, potentially helping to account for a “low heat flow paradox.” The melt welts also may help explain certain questions in earthquake rupture dynamics such as why some slowly slipping tremor-generating events can snowball into massive earthquakes if they pass a velocity tipping point.
“This may be relevant for how you get from large earthquakes to giant earthquakes,” said Brown, who used the example of last year’s magnitude 9.0 earthquake off Japan. “We thought that large patches of the fault were just creeping along at a constant rate, then all of a sudden they were activated and slipped to produce a mega earthquake that produced a giant tsunami.”
Fialko says the melt welt finding could eventually lead to improved “shake” maps of ground-shaking intensities, as well as improvements in structural engineering plans. Future studies include investigations about why the melt welt weakening occurs and if it applies to most or all common fault zone materials, as well as field research to locate melt welts along fault zones.
The Scripps Marine Science Development Center provided the machinery used in the study’s experiments.
