Catalog Errors
l All catalogs have errors, which may render
invalid conclusions derived in a study based on a
catalog of earthquakes.
Two ways to avoid the errors –
l Postpone the analysis until the data are refined;
l Use robust methods within the limits of their
applicability.
“Undue precision of computations is the first
symptom of mathematical illiteracy”
