This is a type-along introductory example to get your feet wet in operating Grond.
We will estimate a centroid moment tensor (CMT) solution given a set of simulated regional full waveform seismic records. Such synthetic tests are useful e.g. for resolution analysis.
A synthetic test¶
With the following few commands, we will let Grond
forward model a fully synthetic scenario of regional seismic waveforms.
setup a processing environment (project folder).
perform a probabilistic optimisation to retrieve a CMT solution for the scenario event.
visualise the results and various details about the optimisation.
grond --help # get list of available subcommands
grond scenario --help # all subcommands come with built-in help
Forward-model a random scenario and create project folder
grond scenario --targets=waveforms my_first_project
Note: precomputed Green’s functions (GF) needed to run this example will be downloaded from the internet.
Check the data setup and configuration
grond check config/scenario.gronf
Start the optimisation
grond go config/scenario.gronf
Plot the results in a report
grond report runs/cmt_scenario_ev001.grun
