European geophysicists say they have discovered a fairly rapid and significant changes in the mass distribution of the liquid core of the planet, as well as the molten metal in the immediate vicinity.
All these changes affect the Earth's magnetic field, and indirectly affect the work of the many services on the planet and its orbit.
According to experts at the German Research Center of Geophysics and Danish scientists from the National Space Institute, with the help of German and Danish satellite CHAMP Orstaed managed to fix the flow at the external borders of the core of the earth at a depth of 3500 km, writes sunhome.ru
Monitoring with satellites and ground stations were for 9 years. During this time, were studied in detail the magnetic field of the planet and created a model that describes the behavior of the outer layers of the core and the molten metal around it.
German experts say that over the past few years has begun to change their model, and the equipment has recorded rapid changes in our planet. Scientists have managed to fix a minor deviation of the field caused by the redistribution of the mass of the nucleus.
The singularity of the situation is that in order to make the most dramatic changes have taken place, the planet took a little less than a year, which is a very short interval of time, given that the previous change of the magnetic field on the Earth happened about 780,000 years ago.
