ABSTRACT: The first part of this investigation analyzes the
deep earthquake occurrences in Nazca subducting under South America. The depth
taken is to get information about possible influences from the unknown
materials and formations under the crust. The
results revealed the presence of malleable material, which is unbreakable and,
therefore, unable to trigger earthquakes. The structure of those
elements is diamagnetic, attracting ionized particles from the Van Allen belt
region in the ionosphere. The charged particles travel towards Earth’s surface, enhanced during the geomagnetic
storms. The South Atlantic Magnetic Anomaly (SAMA) found that the deformation
suffered by the anomaly moving from South Africa to South America is, possibly
due to a bulge of unknown flexible
material buried underneath the oceanic and continental crust. The
continental part is strengthening in weakness because the background also has a
high amount of diamagnetic material in this region, and it would not happen
over the Atlantic Ocean, where part of the deformation is placed.
