Local Statistics of Earthquake Catalogs
In analyzing earthquake catalogs one encounters the problem of distinguishing earthquakes whose occurrence is related to previous earthquakes. This paper investigates the first part of the problem: proof of the existence of interrelated earthquakes (not simply in the trivial case of aftershocks). The study boils down to a comparison of the statistical distributions of certain statistics for an actual earthquake catalog and for a randomized catalog of earthquakes which occur randomly and independently of one another. The catalog of random earthquakes was obtained by random shuffling of an actual catalog.
