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.
