The Anna, Ohio seismic array, converted to solar recharge power systems, has been in continuous operation. No local earthquakes above m sub b 1.5 have occurred. Near regional earthquakes from 1977 through 1980 supplemented with quarry blast recordings have been used to determine the regional travel time curves. Theoretical estimates of earthquake detection and location capabilities for m sub b 2.5, 2.0, and 1.5 earthquakes in the Anna, Ohio region are included to demonstrate the coverage effectiveness of the network. Teleseismic P-wave residuals as a function of azimuth are included to demonstrate the lower crustal velocity variation for the region. Finally, an exhaustive catalog of water and gas well data is included from which a regional depth to bedrock map has been produced.
