Evidence of unusual structural disturbance inside the earth â€“ polar reversal may be root cause of increasing earthquakes and volcanoes â€“ ticking time bomb for 2012?

The earthâ€™s inside, according to scientists consists of an inner core, an outer core, a lower mantle and an outer mantle. Earth's interior is layered something like the inside of a peach. The "pit" at the center of Earth is called the "core". It is made mostly of iron, some nickel, and about 10 to 15% of a less dense material, probably silicon, oxygen, or sulfur. The core itself is made of two concentric pieces, a solid inner core and a liquid outer core. The large zone corresponding to the flesh of the peach is called the "mantle". It is made mostly of rocky minerals with names like olivine, pyroxene, quartz, and periclase. (Any good book on geology or mineralogy will tell you everything you ever wanted to know about these minerals.) Almost all rocks are made of silicon and oxygen mixed with other elements such as calcium, aluminum, and iron. Mantle rock contains particularly large amounts of iron and magnesium. The mantle is also divided into two solid parts, the lower mantle and the upper mantle. This division in the mantle may be due to small differences in the amounts of iron and magnesium or to differences in the nearness of atoms to each other. (As an analog, think of a piece of Styrofoam. If you crush it, the particles inside move closer together because you have closed the tiny open spaces inside, but it is still made of Styrofoam.)

A computer model monitoring the recent seismic disturbances â€“ earthquakes and volcanoes show extreme disturbance in the outer and inner core of the earth. The interaction of the inner core and the rest of the earth cause the electromagnetic properties of the earth. The ongoing polar reversal is accelerating and will eventually have reverse polarity in North and South pole. According to the simulation model, the earthâ€™s inner core and outer core is going through some serious disturbances. That in turn is influencing the viscous semi fluid mantle. When that happens, the convection within mantle increases substantially. That is also influenced by solar polar reversal. In our modern age we have not experienced a simultaneous solar and terrestrial polar reversal. Between now and 2012, these disturbances will keep increasing making earthâ€™s crust and tectonic plates very disturbed causing severe volcanoes and earthquakes.

In the last four months the earth experienced the largest three earthquakes in the last two hundred years. The under water volcanoes and earthquakes have gone up 88% over the last three years. The continental earthquakes have gone up by 62% during the same time frame. The rate of increase of these earthquakes and volcanoes when drawn against time is staggering.

Some scientists are now afraid that we are moving towards 2012 with ticking time bomb under us. Something catastrophic like the lost world Atlantis can repeat.

Pacific 'Ring of Fire' awakened by Indonesian quakes
Wed Apr 13, 1:18 PM ET

MOUNT TALANG, Indonesia (AFP) - Massive quakes in Indonesia have stirred two huge volcanoes from their slumber and sent shockwaves reverberating along a vast and volatile region known as the Pacific "Ring of Fire."

Both on land or underwater, the volatile edges of the north Pacific, bounded by the east Asian rim and the west coast of the Americas, are alive with near-constant seismic activity.

Some of the most dramatic natural disasters of recent history have happened within the Ring's arc, which stretches from Chile, north to Alaska and then west to encompass Japan, Southeast Asia and the Pacific islands.

From the nuclear-like explosion of Krakatoa volcano off Indonesia in 1883 to the eruption of Mount St Helens in the United States in 1980, the Ring's awesome power is legendary.

But it gained new notoriety when on December 26 last year, a massive 9.3 magnitude earthquake occurred off Indonesia unleashing tsunamis that devastated shores around the Indian Ocean, killing more than 220,000 people.

The reason for such geological volatility is the fragile fault lines that ring the zone.

The Earth's crust is made up of a series of rocky plates that literally float on the molten rock of the Earth's mantle and core, interlocked over the entire planet like the pieces of a puzzle.

These plates are in constant motion, clashing into each other or moving away from each other, creating stresses and pressure build-ups at their margins.

The edges, or fault lines, are weak points in the planet's surface where the crust drops to just a few miles in thickness; at its thickest it is about 20 miles deep.

Many, mostly small eruptions occur, but occasionally huge volcanic explosions, earthquakes or landslides are generated, as pent up energy is released through the weak fissures.

Among the most active parts of the ring is the Mariana Trench, near the tiny US-controlled Guam islands, and in recent months, the waters off the southwestern shores of Indonesia's Sumatra island.

Last December's massive quake was created when the Earth's crust shunted a huge 15 metres (50 feet), producing so much energy that the planet wobbled on its axis and tsunamis travelled for thousands of miles.

That quake was followed three months later by another measuring 8.7 on the Richter scale, causing extensive damage to the Sumatra coast islands of Nias and Simeulue, leaving more than 670 dead.

Tremors have continued to shake the region, the latest on Wednesday measuring 5.3, with scientists warning that a third big seismic event could be on the way.

"The probability of a third quake in the coming months and years, cannot be excluded," Mustapha Meghraoui, of the Institute for Planetary Physics in Strasbourg, eastern France, said recently.
