"""
Implements magnitude-area scaling relationship to mimic point ruptures.
Independently of the magnitude value, this scaling relationship returns
always a very small value (1e-4 squared km, corresponding to a 10 by 10 m
square) for the median area.
NOTE: This scaling-relationship is meant to be used in area and point
sources to mimic point ruptures. Is not intended to be used in fault
sources, as it would require a fault surface discretization step to small
(less than 10 m, using an aspect ratio equal to 1) which is unfeasible for
realistic applications.
