Abstract - Power-law fault size (throw) distributions spanning
ca 7 orders of magnitude are analysed using sample lines from seismic,
coal-mine plan and outcrop data sets. Outcrop data sets generally have
lower power-law exponent values than seismic data sets, consistent with
a general decrease in exponent value with decrease in fault size. If such
a relationship does exist then it probably cannot be accounted for by sampling
bias alone. We suggest that, either i) fault-size populations are not power-law
over a large scale range, or ii) they are power-law, but at smaller scales
show a greater range of exponent values due to spatial clustering.
