# Seismic moment‐frequency relation for shallow earthquakes: Regional comparison

@article{Kagan1997SeismicMR, title={Seismic moment‐frequency relation for shallow earthquakes: Regional comparison}, author={Yan Y. Kagan}, journal={Journal of Geophysical Research}, year={1997}, volume={102}, pages={2835-2852} }

We determine the parameter values for the seismic moment-frequency relation using Flinn-Engdahl's regionalization of global seismicity and the Harvard centroid-moment tensor data. The earthquake size distribution is approximated by the gamma law: a version of the Gutenberg-Richter distribution with an exponential taper at the maximum moment. There is no statistically significant variation of the fJ value (the analog of the b value) for all seismic regions except for the midocean ridge systems… Expand
