General Design Memorandum Appendices B J

Awareness of potential seismicity induced by the filling of large reservoirs or by the injection of fluids in boreholes has prompted the Corps of Engineers and others to conduct microseismic monitoring programs at ten damsites and at one injection well. Two other damsites have been monitored by other organizations in cooperation with the Corps of Engineers and one is proposed. These programs were developed to measure and compare ambient seismicity in the environs of the installations and the seismicity present during either reservoir filling or fluid injection.
