Plate-tectonic analysis of shallow seismicity:

Apparent boundary width, beta, corner magnitude, coupled lithosphere thickness, and coupling in 7 tectonic settings

by Peter Bird and Yan Y. Kagan

This supplement presents all the global seismic subcatalogs of shallow earthquakes created and analyzed in this study.

Plots of log-cumulative-number vs. magnitude are also included for maximum-probability subcatalogs.

Note that no original earthquake locations or mechanism determinations were performed;

the new work consists of dividing shallow seismicity by plate boundary setting in systematic ways,

and analyzing the frequency/moment relations of the resulting subcatalogs.
