Technical Report 79-3 SEISMIC ACTIVITY NEAR THE V. C. SUMMER NUCLEAR STATION For the Period July - September 1979 by Pradeep Talwani Principal Investigator Geology Department University of South Carolina Columbia, S. C. 29208 Contract No. N230519

INTRODUCTION

^

This report presents the analysis of seismic data recorded near the V. C. Sumer fluclear Power Station in South Carolina. During the reporting period (July 1 - September 30,1979) shallow micreearthquake activity averaged less than one locatable event per day (= 0.33 event / day).

Only one event of magnitude > 2.0 was recorded (09/14/79) fcr this reporting period.

INETRUfZNTI.TICN The data were recorded by a four station seismic network operated by S. C. E. and G. Data were also cbtained from JSC, a permanent station of the South Carolina seiscographic network. These seismic statior.s are shown in Figure 1 and listed in Appendix I.

1%THCD Events were located using a computer progran HYP0-71 (Lee and Lahr,1972) and a velocity model developed for the Monticello Eeservoir area (Appendix II). The event nagnitudes are calculated from the signal durations at station JSC, where the duration (D) and magnitude (PL )

relaticn is ti = -1.83 + 2.04 log D l

The daily energy release was calculated using a simplified magnitude (li t) energy (E) relation (Cutenberg and Richter, 1956) log 10 E = 11.8 + 1.5 P L

2 RESULTS '

. In the reporting period (July 1 - September 30, 1979) 40 locatable events were recorded. These are listed in Appendix III. Figure 2 shows ymur the cumulative events recorded in July, August and 6tdy 1979. Most events occurred in a group on the western edge of the reservoir with a small portion of the events occurring in the two loose clusters in the central and southwestern parts of the reservoir. A cross section, 2.0 miles in width from A to B is shown in Figure 3, showing the shallcw

( < 4.0 km) character of the events. The monthly locations and cross sections are shown in Figures 4 - 9. A cumulative (from December 1977 to September 1979) map is shown in Figure 10. A cumulative (from December 1977 to September 1979) map of events (f( > 2.0) is shown in Figure 11. In Figures 2 - 11 only events with an Rt1S of _< 0.1 sec have been plotted.

CC.'.'PARISOll OF SEISIIICITY WITil RESERVOIR LEVELS l'anticello reservoir is a pumped storage facility and the decrease in reservoir lavels associated with power generation is recovered when water is pumped back into the reservoir. Correspondingly there can be variations up to about 5 feet per Cay between the maximum and minimum water levels. Figure 12 shows the comparison of water level to seismicity.

The top two graphs shou the water level and also the change of water level per day. The log energy per day and number of events per day are shown on the lower graphs. Only events with a duration of 10 seconds (f( s 0.2) were considered, as the seismic energy release associated with

, smaller events is significantly smaller.

• re7 $ ?.0

3 During the reporting period there were three seismicity peaks;

. these are shown in the lower part of Figure 13 as 1, 2, and 3. There is a suggestion that the three seismicity peaks are related to the preceding low peak in the maxinum water level (lcw change per day).

Figure 13 shows a possible correlation between the low taxitun water levels or small change per day and seismicity. This suggests an increase in seismicity occurring 15 - 20 days after a lcw peak in the maximun water level .

concruszon During this reporting period seismicity was at a low level, but during the month of October 1979 activity greatly increased. This increase in seismic activity during October is presently being studied.
