Transformed plot of the magnitudes distribution of an earthquakes catalog
Description
Plots the logarithm of the cumulative frequency of eccedence vs. magnitude in an earthquake catalog.
Usage
magn.plot(catalog, main = "Transformed plot of magnitude frequencies", ...)
Arguments
catalog |
should be a |
main |
Title to give to the plot |
... |
other arguments to be passed to |
Details
For each magnitude , if
is the number of values of
magn1
greater than ,
the values of
vs.
are plotted.
According to the Gutenberg-Richter law, this plot should be linear. If there is a linear behaviour only for values greater
than a given , then
is probably the magnitude threshold of the catalog.
Value
A new plot is printed (see details).
