             abstract = "On January 20, 2024, a deep-focus earthquake of magnitude 6.6 
                         struck near Tarauac{\'a}, Brazil, at a depth of 607.0\ km. 
                         While no surface damage was reported, this event marked a 
                         significant seismic occurrence in a region known for deep 
                         earthquakes associated with the subducted Nazca Plate. Using 
                         Global Navigation Satellite System (GNSS) Total Electron Content 
                         (TEC) data from the Brazilian Network for Continuous Monitoring of 
                         GNSS Systems (RBMC) and seismic data from the IRIS network, we 
                         analyzed the earthquake's impact on both ground surface (in form 
                         of uplift) and ionosphere (in form of disturbances). The results 
                         show clear ionoquakes characterized by distinct {"}N-type{"} wave 
                         patterns in TEC data, originating from infrasonic-acoustic waves 
                         launched from the earthquake's crustal displacement. The 
                         ionoquakes arrived in the ionosphere 8.3 minutes from the 
                         mainshock onset and traveled with the net propagation speed of 
                         550\ m/s to 743\ m/s. This is the first report on 
                         coseismic ionospheric disturbances, or ionoquakes, following an 
                         earthquake in the Brazilian sector. The spectral analysis shows a 
                         maximum TEC amplitude in the frequency range 14\ mHz 
                         16\ mHz which suggest that the ionoquakes are signatures of 
                         high-frequency infrasonic-acoustic waves dynamics.",
