Additional file 1 of On the observation of magnetic events on broad-band seismometers

Additional file 1: Figure S1. Representative SSC-related seismic signals at QSPA station (South Pole). Each panel shows the acceleration records of SSC events between 2011 and 2018, at the different sensors installed in the same site, all of them represented using a common amplitude scale (m/s2). Note that, although the amplitude of each event are very different, the relative amplitude and polarity differences between sensors remain stable.
