Journal of Geophysical Research -- Planets Supporting Information and Dataset for: The Seismic Signatures of Recently Formed Impact Craters on Mars N.C. Schmerr, M. E., Banks, I. J., Daubar Corresponding author: Nicholas Schmerr (nschmerr@umd.edu) Acknowledgements: This research was supported by grants NASA-MFRP NNX14AQ92G (NS, ID, and MB) and NASA InSight Participating Scientist 80NSSC18K1628 (NS). Introduction The following dataset consists of the seismic waveforms created for studying impact crater clusters on Mars and a table of the parameters used to model each impact in the cluster (Supplemental Table 1). A) Supplemental Table 1: Model parameters used to construct the impact crater cluster simulations for the Daubar et al., (2019) crater database. The table replicates data from Daubar et al., (2019), while the following parameters were derived from crater size and impact geometry: S = Seismic Amplification (Eq. 4) F_ang = Net Seismic Force Incidence Angle (Eq. 5) I = Impact Momentum Tau = Impulse Duration (Eq. 2) As we used two separate impact velocities, we append a 1 to the relevant property for 6.5 km/s and 2 is for 11.5 km/s, e.g., S1 refers to the seismic amplification for an impact with a 6.5 km/s impact velocity. The values 'reg', 'sed', and 'bed' refer to the target material properties, corresponding to "regolith", "cohesive sediments", and "bedrock" respectively. Values of -999.0000 under Azimuth and Angle fields are where there were not enough craters were present to determine these parameters, values of 90 deg and 45 deg were used respectively in the simulations for these impacts. The table is an ascii text file, labeled 'SupplementalTable1.txt' B) The following is a waveform archive of the impact simulations. The waveforms created are archived in ascii text files, each under a directory for a given simulation. In each of these directories are two types of files: 1) the Serpentine Wave Propagation input file (*.in) 2) seismograms in ascii text files (*.txt) For an explanation of the contents in (1) see the documentation for WPP (Petersson & Sjogreen, 2010) and the main text for assignment of impact event properties at each source. This file contains all the information needed to recreate the simulations using WPP2.0 (and its successor SW4); https://geodynamics.org/cig/software/sw4/ The seismograms are stored in the *.txt files under each directory, and the location of each record can be read from the header information at the start of each *.txt file. The header describes the fields in the file and location of the station. The cartesian coordinates of the impact clusters are centered on [10000, 10000] meters in the simulations. AZ (001-322) files are arranged in a lower hemispherical configuration 5 km from the source (in distance and depth) NS (000-020) and EW (000-020) files are arranged in line every 1 km from the source in the North-South (NS) and East-West (EW) directions, starting at the edge of the simulation (000). Note: Despite the use of WGS84 in the header, each latitude/longitude coordinate is adjusted to a Mars radius of 3390 km, with the lower lefthand corner centered on latitude/longitude [0,0] degrees. Files are compressed using "tar -cvzf" which uses gzip compression. The individual directories are gathered into multiple nested tar files, contents are listed in the associated tables below.

Each cluster is associated with the HiRISE Observation ID that was assigned to the locations and impact paremeters (angle, azimumth, crater size) presented in the Supplemental Tables S1 and S2 of Daubar et al., (2019). The Simulation Label indicates which subdirectory the results for the cluster is found under.
