...Linyue Chen; Pradeep Talwani Abstract A surprising increase in seismicity started in and around Monticello Reservoir, South Carolina in December 1996, and by the end of 1999, over 700 earthquakes with –0.4 ≤ M L ≤ 2.5 had been located. This seismicity occurred in a new hypocentral region and filled...

... to the availability of detailed seismicity and geological and in situ stress data at Monticello Reservoir, it was possible to study various factors that control the mechanism of reservoir-induced seismicity. Our results suggest that, during the filling period, the instability resulted from elastic, undrained...

...) . Wells et al. (1990) suggested that this period of dune formation extended from before this date to some time after, noting a reported age of ca. 19 cal ka on bone at the base of a loess unit near Monticello ( Price et al., 1988 ). However, loess deposition need not coincide with sand deposition...

Monticello Dam left abutment three-component broadband velocity waveforms from two 3 March 1998 M ∼1.8 blind thrust earthquakes located 5 km northwest of the Monticello Dam at an elevation of -11 km. The P- and S-wave direct arrivals from each earthquake are labeled as EQ1 and EQ2. The vertical line and small arrow show the travel-time delay of the slow S wave on the east component (bottom) relative to the fast S wave on the north horizontal component (middle).

S-wave time windows from the Monticello Dam north abutment, three-component broadband velocity waveforms are shown on the left from the 11 November 1997, 13:00 UTC, ML 3.5 earthquake located at 39.674° N, 122.146° W at an elevation of –17 km. Corresponding acceleration spectra are plotted on the right. The earthquake was located ∼130-km north of the dam between Willows and Orland. The S “Fmax” labels and arrows on the horizontal components show that S-wave attenuation is relatively low for frequencies up to about 6 Hz. Units are in counts since only the spectral shapes are of interest.

Shows locations of initial seismicity to January 1978 at Monticello Reservoir. Insets show the location of the reservoir in south Carolina and the seismic stations used to locate the earthquakes. Open and solid circles show locations of earthquakes where the undrained effect due to impoundment of the reservoir resulted in weakening and strengthening, respectively. Boxed groups of epicenters and related fault-plane solutions for various locations are from Talwani and Acree (1987). X shows the location of the earthquake showing the largest strengthening. The stippled area shows the deepest part of the reservoir where no initial seismicity was observed. W1 shows the location of deep borehole 1.

Four of the 27 events that occurred ∼10 km SE to the reservoir are shown, and the other 23 are outside the area covered by the figure. Inset shows the location of the reservoir area in South Carolina. Also shown are the locations of two deep wells (W1 and W2) and Virgil C. Summer Nuclear Station (solid square). The seismic stations used to located the events are shown by triangles. MR02 is located about 9 km SSE of station jsc and is shown by a small square in the inset.
