In both Brazil and the United States, seismographs are essential instruments maintained by geological survey agencies. Brazil's Geological Service (CPRM) and the USGS operate extensive seismograph networks. The term is primarily used in academic, scientific, and emergency management contexts. Given Brazil's location on a stable tectonic plate, seismographs are less prominent in public awareness compared to earthquake-prone countries like Japan or Chile.
