Brazil is intraplate and relatively stable, but experiences occasional moderate earthquakes across the continent’s interior. This page pulls real records for Brazil: the largest earthquakes on record from USGS, how often the ground shakes nearby, tsunamis from the NOAA database, and volcanoes from the Smithsonian program. Nothing is guessed.
A quiet recent record is good news, but many damaging earthquakes strike places that were quiet for decades. The only real protection is a warning the moment the ground moves - which is exactly what the free QuakeMate app gives you, along with tsunami and volcano alerts for Brazil.
