csep.core.regions.generate_aftershock_region(mainshock_mw, mainshock_lon, mainshock_lat, num_radii=3, region=<function california_relm_region>, **kwargs)[source]

Creates a spatial region around a given epicenter

The method uses the Wells and Coppersmith scaling relationship to determine the average fault length and creates a circular region centered at (mainshock_lon, mainshock_lat) with radius = num_radii.

Parameters:

  • mainshock_mw (float) – magnitude of mainshock

  • mainshock_lon (float) – epicentral longitude

  • mainshock_lat (float) – epicentral latitude

  • num_radii (float/int) – number of radii of circular region

  • region (callable) – returns csep.utils.spatial.CartesianGrid2D

  • **kwargs (dict) – passed to region callable

Returns:

csep.utils.spatial.CartesianGrid2D
