                         ser{\~a}o abordados os seguintes t{\'o}picos: (1)

                         Hilbert-Huang (HHT) e Transformada Wavelet Cont{\'{\i}}nua

                         s{\'e}ries temporais; (2) An{\'a}lise dos dados de Conte{\'u}do

                         TEC), do campo geomagn{\'e}tico e de sismogramas utilizando para 
                         isso receptores GNSS (Global Navigation Satellite System), 
                         magnet{\^o}metros e sism{\^o}metros, respectivamente; (3)

                         dos SAIDs, baseado no mecanismo que envolve as ondas 
                         s{\'{\i}}smicas, atmosf{\'e}ricas e ionosf{\'e}ricas. Para 
                         isso, foram escolhidos tr{\^e}s eventos de terremoto de 
                         diferentes magnitudes, um deles de magnitude moderada equivalente 
                         {\`a} MW=6,3, e outros dois de magnitudes fortes equivalentes 
                         {\`a} MW=6,8 e {\`a} MW=7,1. Os resultados obtidos s{\~a}o os 
                         seguintes: (1) SAIDs podem ser identificados nos dados 
                         ionosf{\'e}ricos, (2) SAIDs associados com eventos fortes 
                         s{\~a}o detectados ambos qualitativamente e quantitativamente, 
                         (3) SAIDs associados com o evento moderado s{\~a}o detectadas 
                         apenas qualitativamente, (4) Uma tentativa sucedida de detectar 
                         SAIDs de evento moderado como obtido nesta 
                         disserta{\c{c}}{\~a}o, pode vir a facilitar a previs{\~a}o de 
                         terremoto forte, (5) SAIDs s{\~a}o gerados devido ao acoplamento 
                         Litosfera-Atmosfera-Ionosfera (LAI) em que as ondas 
                         atmosf{\'e}ricas amplificam sua amplitude a uma taxa de 1 mm/s em 
                         rela{\c{c}}{\~a}o {\`a} superf{\'{\i}}cie da Terra. ABSTRACT: 
                         This dissertation aims to investigate {"}Seismic Triggered 
                         Traveling Ionospheric Disturbances{"} (SAIDs) over South America, 
                         using geomagnetic and ionospheric data. This subject is relatively 
                         new in the context of South America that often hosts seismic 
                         activities. The objective of this work is to apply the tools of 
                         data analysis obtained with several instruments and their 
                         interpretations, which can facilitate the prediction of 
                         earthquakes and tsunamis. In this way the following topics will be 
                         addressed: (1) Application of Hilbert Huang Transform (HHT) and 
                         Continuous Wavelet Transform (CWT) to analyze the time series and 
                         the propagation of the waves, (2) Analysis of the Total Electron 
                         Content (TEC) data, Geomagnetic field and the seismic waves 
                         through Global Navigation Satellite System (GNSS) receivers, 
                         magnetometers and seismometers, respectively. (3) Interpretation 
                         of the SAIDs observed characteristics, based on the mechanism that 
                         involves the atmospheric seismic waves and ionospheric waves. We 
                         choose three earthquake events of different magnitudes, one of 
                         moderate magnitude equivalent to MW = 6.3, and two others of 
                         strong magnitudes equivalent to MW = 6.8 and MW = 7.3. The 
                         expected results are as follows: (1) SAIDs can be identified in 
                         the ionospheric data, (2) SAIDs associated with strong events are 
                         detected both qualitatively and quantitatively, (3) SAIDs 
                         associated with the moderate event are only detected 
                         qualitatively, (4) a successful attempt to detect moderate event 
                         SAIDs facilitates strong earthquake prediction, (5) SAIDs are 
                         products of Lithosphere Atmosphere Ionosphere (LAI) coupling in 
                         which atmospheric waves amplify their amplitude at a rate of 1 
                         mm/s relative to the Earths surface for a 10 m/s wind in the 
                         ionosphere, that can generate detectable SAIDs.",
