Extended Data Fig 1: Analysis of the seismic event observed on Sol 189.

a, Acceleration spectrogram for entire sol (top) and zoom around the event (bottom) with event start and end times (utc) marked. b, Three component seismic channels in m/s (VBB, 20 sps) with MQS phase picks and uncertainties. c, Auxiliary channels used when analysing the data. Timing of b and c match the bottom spectrogram in a. VBB is the very broadband seismometer, and MAG1/2/3 are the three magnetometer channels. The only lander activity during the event period (UHF communication) is marked with shaded area on the MAG channels. Time span shown in Extended Data Fig. 2 is marked in the 24hour window at the top of a.
