The Narrows, Virginia earthquake of March 8, 1968 was located at 37.3° N., 80.8° W., with an origin time of 05:38:15.2 GMT. The Eastern Tennessee crustal model of Steinhart and Meyer (1961) was employed for this location, and the resulting travel-time residuals for seven stations showed a standard deviation of 0.4 second. This fit to the observed travel times implies that the Eastern Tennessee model may be more appropriate for the region than the standard Jeffreys-Bullen crustal model. Macroseismic data for the earthquake gave a maximum intensity (MM) of IV and a felt area of approximately 3200 square miles.
