Quickstart
|
|
==========
|
|
|
|
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.

|
|
|
.. code-block :: sh
|
|
|
|

*Note: precomputed Green's functions (GF) needed to run this example will be
|
|
downloaded from the internet.*

**Check the data setup and configuration**
|
|
|
|
.. code-block :: sh
|
|
|
|
cd my_first_project
|
|
grond check config/scenario.gronf
|
|
|
|
**Start the optimisation**
|
|
|
|
.. code-block :: sh
|
|
|
|
grond go config/scenario.gronf
|
|
|
|
**Plot the results in a report**
|
|
|
|
.. code-block :: sh
|
|
|
|
grond report runs/cmt_scenario_ev001.grun
|
|
|
|
**Open the report in your web browser**
