More information on Martian seismicity can be found in Knapmeyer et al. (2006):

We arbitrarily select two models from our list of models to reflect thin and thick crust: C30VH-AKSNL-1s and C80VH-AKSNL-1s, respectively. We also produce waveforms with and without surface noise. In order to identify these different combinations, we use the location code segment of miniseed file names. Our waveforms are stored in SDS archive format: the file names are constructed using network, station, location, and channel codes combined with the year and day of year in order. (e.g. 7J.SYNT1.01.BXZ.D.2019.289). Below tables show the constant parameters and some examples to describe our file naming convention.

  

Field names used in miniseed file names

Name Value
Year of simulation 2019
Network code 7J
Station code SYNT1
Channel codes BXN (north), BXE (east), BXZ (vertical)
Location codes 00: Thin crust, no noise
01: Thin crust, with noise
10: Thick crust, no noise
11: Thick crust, with noise
