In etasFLP: Mixed FLP and ML Estimation of ETAS Space-Time Point Processes for Earthquake Description

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 eqcat object, or at least must contain a column with name magn1.
main	Title to give to the plot
...	other arguments to be passed to plot()

Details

For each magnitude m_j, if N_j is the number of values of magn1 greater than m_j, the values of \log(N_j) vs. m_j 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 m_0, then m_0 is probably the magnitude threshold of the catalog.

Value

A new plot is printed (see details).
