A different interpretation of the annual and semiannual anomalies on the magnetic activity over the Earth
(American Geophysical Union, 2012-07)
The H component of the magnetic field measured at the terrestrial surface presents several periodic signals caused by changes in the ring current that flows within the terrestrial magnetosphere. One of the most important ...
Intrusao alcalina de Jaboticabal, SP.
(1984-12-01)
Five magnetic anomalies were found and mapped in the Faculdade de Ciencias Agrarias e Veterinarias, UNESP, campus of Jaboticabal, SP. The study showed that those anomalies represent intrusive alkaline bodies linked to ...
Variations of geomagnetic cutoff rigidity in the southern hemisphere close to 70°W (South-Atlantic Anomaly and Antarctic zones) in the period 1975–2010
(Elsevier Ltd, 2019)
© 2018 COSPARWe report the existence of rapid variations in (effective) geomagnetic cutoff rigidity (Rc) between the equatorial and Antarctic zones adjacent to the Andes Mountains, revealed by the variation rate of geomagnetic ...
Fractal clustering as spatial variability of magnetic anomalies measurements for impending earthquakes and the thermodynamic fractal dimension
(2022)
Several studies focusing on the anomalies of one specific parameter (such as magnetic, ionospheric, radon release, temperature, geodetic, etc.) before impending earthquakes are constantly challenged because their results ...
