Chile: Earthquakes can be predicted
The researchers found a relationship between the magnetic fields and the earthquakes they observed in the Maule, Sumatra and Japan earthquakes.
After three years of research, a group of scientists from the Department of Physics, FCFM of the University of Chile discovered a relationship between magnetic fields and earthquakes that would be transcendental for the prediction of earthquakes.
According to T13, Enrique Cordaro, an academic from the DFI, said that in the study they found that "the protection afforded by the Earth's magnetic field against space radiation is strongly related to tectonic plates and earthquakes in the country." He further added, it is a first step before the possibility of predicting earthquakes, for which it is necessary to continue with this investigation.
Cordaro said that during the investigation they noticed that the magnetic field has been decreasing in the country, due to the magnetic anomaly of the South Atlantic, a phenomenon that extends from Chile to Zimbabwe and that increases the exposure of space radiation, as per T13.
Thus, it arose in the interest of the scientists in this area and they decided to study it, discovering that the magnetic field had a behaviour that has been repeated in earthquakes such as those of Maule in 2010, Sumatra in 2004 and Tohoku (Japan) in 2011 , places where sharp changes were observed in the magnetic field near these places before the earthquake and oscillations that ended just when the earthquake occurred.
This discovery could allow to define a waiting time between the sudden change and the end of the existence of oscillations.
