This report is to cover the results of the CDE se1smic monitoring program during the period from July 15, 1981 through December 31, 1983. The results of the preceeding period were reported in the Technical Report #1-#3 and a number of Field Reports submitted during the period of June 1979 through July 1982. The summary of the previous works carried out under this program is given in section 2. After the completion of Bao Dam, impounding of the Bao reservoir started in February 1983. At the time of this writing (August 1984) the water loading into Bao reservoir is still continuing and the water level is 7 meters short of full capacity. Throughout this reporting period which covers the initial phase of loading period no significant increase of seismicity was recognized in the immediate proximity of the reservoir. This quiescence, however, does not mean there will be no induced earthquake since the water level still may not have reached the crucial level by the end of December 1983. Continued monitoring at least six to twelve months after the completion of loading is recommended.
