Supplement to
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.
