| Abstract | |
In this work, we present a first report on magnetic disturbances over the Brazilian sector that occurred on September 16-17, 2015. These disturbances are associated with the Illapel earthquake. Using seven magnetometers installed across Brazil, and distributed within 4500 km from the epicenter, the presence of magnetic disturbances is noted similar to 15 min after the time of earthquake. The seismometers registered the arrival of the first seismic waves similar to 10 min prior to the observed signatures on magnetic disturbances, suggesting that such waves are possibly from seismogenic origin, which involves the lithosphere-atmosphere-ionosphere coupling.
