TECHNICAL REPORT 93-3 SEISMIC ACTIVITY NEAR THE V.C. SUMMER NUCLEAR STATION- '
FOR THE PERIOD JULY-SEPTEMBER,1993 i BY PRADEEP TALWANI Principal Investigator and Robert Trenkamp-l DEPARTMENT OF GEOLOGICAL SCIENCES UNIVERSITY OF SOUTH CAROLINA COLUMBIA, SOUTH CAROLINA 29208 j CONTRACT NO. N622702 ,
INTRODUCTION Analysis of the seismic activity near the V.C. Summer Nuclear Station in South Carolina between July 1 and September 30,1993 is presented in this report. During this period, seven events were recorded in the vicinity of the Monticello Reservoir. All l seven events were located and were of relatively small magnitude.
l SEISMIC NETWORK 1 Earthquakes during this, period were recorded on stations of Monticello Reservoir and l South Carolina Seismic Networks. The configuration of stations utilized to locate l Monticello Reservoir events is shown in Figure 1 and station coordinates are listed in ;
Appendix I. The operational status of the network is given in Appendix II.
DATA ANALYSIS Hypocentral locations have been determined using the computer program HYPO 71 (Lee and Lahr,1972). The velocity model used in the earthquake locations is given in Appendix III. The format of the HYPO 71 output is given in Appendix IV. The event magnitude was determined from the signal duration at JSC using the following relation:
M t= -1.83 + 2.04 Log D, where D is the signal duration (seconds).
An estimate of daily energy release was determined using a simplified magnitude (ML ).
energy (E) relation by Gutenberg and Richter (1956):
Logio E = 11.8 + 1.5 Mt OBSERVED SEISMICITY DURING JULY-SEPTEMBER,1993 Seismicity around Monticello Reservoir was low during the third quarter of 1993.
Seven events were recorded and located (Figure 2). Five events were located which occurred during a six hour interval on September 6,1993 between 11:22 and 17:17 UTC.
- They were located in a cluster near Stadon MR10 and to its west. The largest event of i
the quarter occurred on July 14,1993 at 20:06:13 UTC and had a duration magnitude of l 0.16. It was located on the east central section of the reservoir near Station MR01 l (Figures 1 and 2). The final event of the quarter had a duration magnitude of -0.27 and l was located south of the reservoir (Figure 2). All locations were rated good to fair (B-C; l Appendix V). The long term decline in seismicity observed at Monticello Reservoir is
! continuing (Figure 3), and the cumulative seismicity has shown relative flattening since 1985-86 (Figure 4).
l
! 1
CORRELATION OF WATER LEVEL WITH SEISMICITY Monticello Reservoir is a pumped storage facility. Any decrease in the reservoir level associated with power generation is recovered when water is pumped back into the reservoir. There can be normal variations up to five feet per day between maximum and minimum water levels. The water level has been monitored to see if there is any correlation between the daily or seasonal changes in the reservoir level and the local seismicity. Water levels are compared with seismicity in Figure 5. The top panel shows the average water level;,the error bars show the maximum and minimum water levels each day. The second panel shows the change in water level from day to day. The i number of events per day and the log of energy released are shown in the lower histograms. These charts include all reported earthquakes listed in Appendix V. The average water level, daily changes in water level, number of earthquakes and energy
' release are given in Appendix VL No systematic correlation was observed between the seismicity and reservoir level fluctuations.
l CONCLUSIONS l
l Seismicity during the third quarter of 1993 was low and occurred generally in the I central and southern part of the reservoir. No systematic correlation was observed between the reservoir level fluctuations and the seismicity.

Column 3 T.atitude (N) degrees, min.
Column 4 Longitude (W) degrees, min.
Column 5 Depth (km).
Column 6 Local duration magnitude.
Column 7- No. of station readings used to locate event. P and S arrivals from same stations are regarded as 2 readings.
Column 8 Largest azimuthal separation in degrees between stations. 1 Column 9 Epicentral distance in km to nearest station.
Column 10 Root mean square error of time residuals in sec.
RMS = Ri 2/No, where Ri is the time residual for the ith station.
Column 11 Standard error of the epicenter in km*.
Column 12 Standard error of the focal depth in km*.
Column 13 Quality of the epicentral location.
- Statistical interpretation of standard errors involves assumptions which may not be met in earthquake locations. Therefore standard errors may not represent actual error limits.
Note: If ERH or ERZ is blank, this means that it cannot be computed, because of insufficient data.
