Catalog#

Catalog#

Simple representation of an earthquake catalog, storing each single event as a row.

Constructor#

A catalog of seismic events represented in tabular form, where each row corresponds to a single earthquake.

`Catalog.from_quakeml`	Create a Catalog from a QuakeML file.
`Catalog.from_dict`	Create a Catalog from a list of dictionaries.

Estimate from Catalog#

`Catalog.estimate_b`	Estimates b-value of the Gutenberg-Richter (GR) law, using the magnitudes in the Catalog.
`Catalog.estimate_a`	Estimates a-value of the Gutenberg-Richter (GR) law, using the magnitudes in the Catalog.
`Catalog.estimate_mc_ks`	Returns the smallest magnitude in a given list of completeness magnitudes for which the KS test is passed, i.e., where the null hypothesis that the sample of magnitudes is drawn from a Gutenberg-Richter law cannot be rejected.
`Catalog.estimate_mc_b_stability`	Estimates the completeness magnitude (mc) using b-value stability.
`Catalog.estimate_mc_maxc`	Returns the completeness magnitude (mc) estimate using the maximum curvature method.

Estimate from Catalog#

`Catalog.plot_in_space`	This function plots seismicity on a surface.
`Catalog.plot_mags_in_time`	Creates a scatter plot, each dot is an event.
`Catalog.plot_cum_count`	Plots cumulative count of earthquakes in given catalog above given Mc through time.
`Catalog.plot_fmd`	Plots frequency magnitude distribution.
`Catalog.plot_cum_fmd`	Plots cumulative frequency magnitude distribution, optionally with a corresponding theoretical Gutenberg-Richter (GR) distribution.
`Catalog.plot_mc_vs_b`	Plots the estimated b-value in dependence of the completeness magnitude.

Modify Catalog#

`Catalog.bin_magnitudes`	Rounds values in the `magnitude` column of the catalog to a given precision `delta_m`.
`Catalog.strip`	Remove all columns except the required ones defined in `_required_cols`.
`Catalog.drop_ids`	Drop event, origin, and magnitude IDs from the catalog.
`Catalog.drop_uncertainties`	Drop uncertainty columns from the catalog.

Convert from and to other format#

`Catalog.to_quakeml`	Convert the catalog to QuakeML format.
`Catalog.from_quakeml`	Create a Catalog from a QuakeML file.
`Catalog.from_openquake`	Create a (seismostats) Catalog from an openquake Catalogue.
`Catalog.to_openquake`	Converts the Catalog to an openquake Catalogue The optional dependency group openquake is required for this method.
