Flinn-Engdahl Regionalization Files

The directory /feregion contains the data files for the 1995 (latest) revision of the Flinn-Engdahl (F-E) seismic and geographical regionalization scheme, which is used by many seismologists to associate seismological data to general regions of the Earth. This directory also includes a set of Fortran programs to install and run the regionalization package. Note that the file names.asc contains the region names currently used by the USGS/NEIC (World Data Center for Seismology, Denver). See our Region Name page for references and some disclaimers.
