CONCLUSIONS <br />The seismic network is operational. The seismic activity in the North Fork Valley is being recorded <br />and the largest events are being processed. Station delays to account for station elevation <br />differences will be necessary to precisely correlate the events with the mining activity. <br />References: <br />Brown, Steve, Geotechnical evaluation of mine-induced seismicity on Monument Dam, Delta <br />County, Colorado, 2005, GEI Consultants, Inc., Englewood, Colorado 80112, 2005. <br />Huzjak, Robert J., Geotechnical evaluation of mine-induced seismicity on Bruce Park Dam, Delta <br />County, Colorado, 2002, GEI Consultants, Inc., Englewood, Colorado 80112, 2002. <br />Johnson, L., and Butler, David, Prediction analysis applied to local hypocenter location, <br />Soc.Exp.
