GRRateGrid

class seismostats.GRRateGrid(data=None, *args, name=None, starttime: Timestamp | None = None, endtime: Timestamp | None = None, **kwargs)

A subclass of pandas DataFrame that represents a grid where for each grid cell, the GR parameters a, b, and mc and number_events are stored.

To be a valid RateGrid object, the DataFrame must have the following columns: longitude_min, longitude_max, latitude_min, latitude_max, depth_min, depth_max, number_events, a, b, and mc.

Parameters:

• data – array-like, Iterable, dict, or DataFrame, optional Data to initialize the catalog with.

• name – Name of the catalog.

• starttime – Start time of the catalog. If a string, it must be in a format that can be parsed by pandas.to_datetime.

• endtime – End time of the catalog. If a string, it must be in a format that can be parsed by pandas.to_datetime.

• kwargs – Additional arguments and keyword arguments to pass to pandas DataFrame constructor.

Methods

add_time_index	Create MultiIndex using starttime, optionally endtime and a cell number for each spatial block.

strip	Remove all columns except the required ones defined in _required_cols.
