Map of permanent broadband seismic stations in Antarctica

– Map of permanent broadband seismic stations that have reported data to the Incorporated Research Institutions for Seismology Data Management Center since 1 January 2010. Global Seismographic Network (GSN) and affiliate stations are shown in green stars, with labels indicating station code and parenthetical rankings (out of 150 GSN stations) used by the National Earthquake Information Center for preliminary earthquake locations during a 1-year period (14 July 2019 to 14 July 2020). The GSN station at Quiet South Pole, Antarctica (QSPA) is the only permanent broadband station in a 12° area, roughly the size of the combined Mountain West and Great Plains regions of the United States (inset).
