http://video.ministryofstars.com/video/invertion_des_poles/inversion_des_poles_3.flvthe earth's magnetic pole shift
The spectacular phenomenon of the earth's magnetic pole shift would not occur at random as previously thought scientists. The work of the University of Calabria lean more to a kind of "memory" of the Earth, which would reproduce the inversion in a particular temporal distribution.
It has happened hundreds of times in 160 million years ago ... when the North becomes South, it is called inversion of the magnetic poles. The last time there was 780 000: an event called inversion-Brunhes Matayama. When will the next episode?
This natural phenomenon, among which are the most amazing, has long been studied and the question is almost valid. Indeed the implications are huge even if the process is not instantaneous, the complete reversal of polarity of the planet that can take hundreds of years. During a very short time, when the total inversion, there is a disappearance of the magnetic field and the planet is no longer protected from radiation from space. The cosmic bombardment and have led in the past mass extinctions of species and the emergence of new ones. However, a number of data, such as the weakening of the total magnetic field seen for over a century could foreshadow a possible magnetic reversal by some thousands of years.
But the phenomenon itself is not really explained. In this context, an Italian team led by Vincenzo Carbone (1) shows that the events would not occur randomly, as was previously thought, but occur in "clusters" (clusters) according to a revealing series kind of magnetic memory of the Earth.
The Earth keeps a magnetic memory
Depending on the state of science, geophysicists believe that the core of the Earth behaves as a kind of giant dynamo producing a magnetic field. This may stop working spontaneously or following a shock, as the impact of a celestial object, then leave with different directions of magnetic fields. According to prevailing theory, the pole shift would obey a Poisson distribution, which calculates the probability of occurrence of events during a set time when they are independent of each other and random. But if one believes Carbone, who conducted a thorough and careful statistical analysis of different samples of physical and geological data derived from periods of inversion, the sequence of appearance corresponds to a Lévy distribution. Explanation: the events occur over time in a correlated cluster ("clusters") rather than randomly and independently of each other.
This "memory" of the Earth is a breakthrough in understanding the geomagnetic and could provide a way a forecast. Italian researchers want to build a dynamic model to describe the process of inversion, to help better understand the physical mechanisms that are at the origin.
