Seismic signals at QSPA station (South Pole). a Top panel: magnetic field (H) recorded at the SBA magnetic observatory, located at the Scott Base (77.85º S, 166.78º E). Bottom panel: seismic acceleration records during the 2014/12/23 SSC event at the different sensors of the QSPA site, represented in normalized amplitudes. b Same data represented using a common amplitude scale. c Seismic records of an M 6.3 earthquake with epicenter in Indonesia represented in true amplitude
