Plotting depth and hypocenter results¶

Suppose we are running a grid search over both origins and moment tensor sources:

ds = grid_search(data, greens, misfit, origins, sources)

After the above command finishes, the data structure ds will contain all the moment tensors and corresponding misfit values.

Plotting misfit versus depth¶

If origins represents different depths, we can plot the results as follows:

from mtuq.graphics import plot_misfit_depth
plot_misfit_depth(filename, ds, origins)

To display tradeoffs with depth, we can add the following keyword arguments:

plot_misfit_depth(filename, ds, origins, show_tradeoffs=True, show_magnitudes=True)

Warning

1D Green’s functions are used for the hypocenter grid search example.

(3D Green’s functions would provide more meaningful results, but are too large for remote hosting.)

If origins represents different hypocenters, we can plot the results as follows:

from mtuq.graphics import plot_misfit_latlon
plot_misfit_latlon(filename, ds, origins)

Warning

1D Green’s functions are used for the hypocenter grid search example.

(3D Green’s functions would provide more meaningful results, but are too large for remote hosting.)

To see how orientation trade offs with hypocenter, we can add the following keyword argument:

plot_misfit_latlon(filename, ds, origins, show_tradeoffs=True)
