Weakening of Earth's magnetic field is a harbinger of increase in frequency and severity of natural disasters. Changes in the tension of Earth's magnetic field are happening unevenly along the surface and reach maximum values in the Western Hemisphere. This suggests that on these territories the strongest disasters should be expected in the coming years.
Earth's magnetic field is a natural "shield" of the planet protecting all life on it from harmful space and solar radiation. In fact, if the Earth had not have its own magnetic field, then life on it in its usual for us form would have been impossible.
However, observations show that Earth's magnetic field is gradually weakening, and with this the geomagnetic poles are moving. Data transmitted by Swarm satellites, launched by European Space Agency (ESA) confirms the common tendency of the magnetic field weakening. The most significant level of decrease is observed in the Western Hemisphere of our planet.
While analyzing the consequences of many natural disasters, scientists came to a conclusion that right before the seismic activity the anomalies in Earth's magnetic field appear. In particular, the activation of the Pacific lithospheric plate in subduction zones preceded the earthquake that happened in Japan on March 11, 2011. This event became a sort of an indicator of a new phase of seismic activity, related to the acceleration of the movement of this lithospheric plate.
The displacement of geomagnetic poles located in Eastern Siberia and Pacific Ocean due to cosmic factors led to colossal changes of the age-old magnetic variations on the territory of the Japanese archipelago. The result of these events was a series of powerful 9.0 magnitude earthquakes.
According to the official data, Earth's magnetic field is weakening 10 times faster now.
The weakening was even more significant in the area of so-called South Atlantic anomaly off the coast of Brazil.
In addition, holes in Earth's magnetic field are a sort of breaches in the magnetosphere through which huge flows of solar radiation penetrate. For unknown reasons the number of these holes is constantly growing.
It is known that the weakening of Earth's magnetic field leads to a polarity reversal in which the north and south magnetic poles switch places and their reversal occurs. Paleomagnetism research showed that earlier in times of polarity reversals, which occured gradually, Earth's magnetic field has lost dipole structure. The inversion of the magnetic field was preceded by its weakening, and after that the field value increased again and reached the previous values.
In the past, similar inversions occured on average every 250,000 years. But since the last one it's been about 780,000 years, as scientists say. However, science has no official explanation for such a long period of stability. One way or another, but current rapid weakening of the magnetic field is a sign of the beginning of global processes in space and inside the Earth. That is why the cataclysms taking place on the planet are caused largely by natural factors rather than human impact. Traditional science faces certain difficulties trying to answer the questions: What happens to the magnetic field at the time of inversion? Does it disappear completely or is it weakening to certain critical values? There are many theories and hypotheses concerning this subject but none of them seems reliable. The very fact of a significant magnetic anomaly happening at the time of polarity reversals can lead to global tectonic changes on Earth, and also pose a serious threat to all life on the planet because of the rising level of solar radiation.
