Flinn-Engdahl regions
The Flinn-Engdahl regions were first proposed by Flinn and Engdahl (1965), with the standard defined by Flinn et al. (1974). The latest version of the schema published by Young et al. (1996) divides the Earth into 50 seismic regions, which are further subdivided, producing a total of 754 geographical regions. The geographic regions are numbered 1 to 757 with regions 172, 299 and 550 no longer in use. The boundaries of these regions are defined at one-degree intervals .
