Scientists Reporting Mysterious shifting of the earth's core

Earth’s Core ‘Mysteriously’ Shifts Causing near Simultaneous Antipodal Earthquakes in Central America, South America and Indonesia
Russian scientists are reporting that the Earth’s core has experienced a mysterious ‘shifting’, as yet for unexplained reasons, but has caused near simultaneous earthquakes in both the countries of Indonesia and its antipodal counterparts of Panama, Venezuela and Nicaragua.
United States Space Agency NASA stated; "NASA scientists using data from the Indonesian earthquake calculated it affected Earth's rotation, decreased the length of day, slightly changed the planet's shape, and shifted the North Pole by centimeters. The earthquake that created the huge tsunami also changed the Earth's rotation."
When North Becomes South: New Clues to Earth's Magnetic Flip-Flops
Our planet's magnetic field reverses about once every 200,000 years on average. However, the time between reversals is highly variable. The last time Earth's magnetic field flipped was 780,000 years ago, according to the geologic record of Earth's polarity. It is not a matter of whether it will happen, but when.
Next time Earth's magnetic field flips, compass needles will point South instead of North. But scientists can't say when it will occur, and until now they've disagreed on how long the transitions take.
A new study pins down how long it took for the last four reversals to play out. It also finds that the dramatic turnarounds occur more quickly nearer the equator than at higher latitudes closer to the poles.
That means folks living during the next reversal -- which some scientists speculate might be underway -- will see compasses change and behave differently in different locations.
It is generally accepted that during a reversal, the geomagnetic field decreases to about 10 percent of its full polarity value," Clement said. "After the field has weakened, the directions undergo a nearly 180 degree change, and then the field strengthens in the opposite polarity direction. The magnetic field lines extend out beyond Earth's atmosphere and provide the first line of defense against strong solar storms.
Earth's Magnetic Field Is Fading
Earth's geodynamo creates a magnetic field that shields most of the habited parts of our planet from charged particles that come mostly from the sun. The field deflects the speeding particles toward Earth's Poles.
Without our planet's magnetic field, Earth would be subjected to more cosmic radiation. The increase could knock out power grids, scramble the communications systems on spacecraft, temporarily widen atmospheric ozone holes, and generate more aurora activity.
Cracks in Earth's Defenses Let Space Storms In
Earth's magnetic field emanates from the poles and extends beyond the atmosphere and past the highest Earth-orbiting satellites.
Earth's natural defenses are routinely compromised by huge cracks that open up for hours, allowing space storms to pour through like a hurricane through an open window.
The magnetic field absorbs the brunt of a solar storm, which is a huge cloud of charged particles, ions and electrons. The Sun constantly spits out a "wind" of these particles. During intense activity, it can shoot a coronal mass ejection (CME) our way. A CME -- the most damaging sort of solar storm -- is to the solar wind what a hurricane is to a summer breeze.
Magnetic Storms Rip Through Earth's Magnetosphere
A magnetic storm produces about a million megawatts of electricity, enough to power the United States. the Sun regularly sends massive solar explosions of radiative plasma with the intensity of a billion megaton bombs hurtling through the solar system. The travel time for the solar wind from the Sun to the Earth is two to four days.
The Sun's corona can rip open and spew as much as 20 billion tons of material into space -- equivalent to the mass of 200,000 cruise ships. These explosions are known as coronal mass ejections (CMEs), the hurricanes of space weather.
When a CME ploughs into the solar wind, it can create a shock wave that accelerates particles to dangerously high energies. Behind that shock wave, the CME expands into a huge cloud that engulfs planets in its path with plasma.
The solar wind pushes and stretches Earth's protective magnetic field into a vast, comet-shaped region called the magnetosphere. The magnetosphere and Earth's atmosphere protect us from the solar wind and other solar and cosmic radiations.
Luckily for us, few CMEs are aimed at the Earth. If a CME erupts on the side of the Sun facing us, the results around Earth can be spectacular and sometimes hazardous.
At the speed of light, flashes of X-rays and ultraviolet rays from the Sun arrive at the Earth in 8 minutes. Hitting the atmosphere they cause disturbances in the ionosphere, which reflects radio signals. Changes in the ionosphere can interrupt short-wave radio transmissions and cause errors in navigation systems.
