The "nearok" list for 1977 through 1997 contains earthquakes which are
mostly located only by the Oklahoma Geological Survey. Some, mostly
magnitude 3.0 and above, are located by the US Geological Survey also.
Some of the Kansas locations 1n 1979, 1980, and 1981 were by the Kansas
Geological Survey.

The area which includes most earthquakes in this list is a rectangle from
32degN to 40degN latitude and 92degW to 103degW longitude.

Being entirely "outside" the OGS network, these epicenters are less accurate
than those in Oklahoma (Kansas Geological Survey epicenters excluded).
These epicenters are included because most of them are not located by any
other agency.

The completeness in the area given is not clear. A few magnitude 1.6 and
smaller are detected. Probably the list is 90% complete for magnitude 2.5
and greater. As some of the Kansas epicenters were located by a network
of the Kansas Geological Survey which operated only a few years, the
area from 38 N to 40 N may be less complete.
