Hi, I think this is one of the best resources that can point you in the right direction. At the end of the book, you will find some code. Mignan, A., and J. Woessner (2012). Estimating the magnitude of complete- ness in earthquake catalogs, Community Online Resource for Statistical Seismicity Analysis, 1–32, doi: 10.5078/corssa-00180805.

Adebayo Ojo Thank you.

The book mentioned the zamp package, but I found that the link could not be opened. If this software is free and available for download, please let me know.

Dear Jiansheng Yu,

You can use the EQcorrscan package (open source), which is an open library running in python. In that package the method eqcorrscan.utils.mag_calc.calc_b_value calculate the completeness with a power law fit.

The package can be found in https://eqcorrscan.readthedocs.io/en/latest/index.html

Best Wishes!

Hi, ZMAP can be found here:

I hope you find it useful.

Thanks Adebayo.

Marcos Ferreira Thank you.

What is a-annual in the FMD graph in ZMAP?

Can it be used to calculate the probability of exceedance of threshold magnitude?

I need to use Z map data in R-Crisis for PSHA analysis.
