RESPONSE

A. Mammoth Lakes earthquake response spectra for a nearby magnitude 4-5 event i i The Mammoth Lakes, earthquake sequence of 1980 occurred predominantly within the Sierra Nevada immediately to the south of Long Valley Caldera Site conditons within the caldera, where many seismographic instruments were deployed for reasons of accessibility and logistics, do not resemble the site conditons at the Virgil C. Summer Nuclear Station. Descriptions of surficial geologic conditions at instru-ment sites located outside the caldera are given in Table 361.25-1. The site for which seismic absorption effects would be expected'to be lowest is the McGee Creek site, which was occupied by a wideband digital displacement seismograph system. This site is taken to be the mos't similar to the Summer site. The McGee Creek site is centrally located with respect to epicenters of the carthquake sequence (Figure 361.25-24). Hypocentral distances, seismic moments, peak horizontal ground accelerations and Richter magnitudes are given in Table 361.25-2 for all events recorded at McGee Creek with magnitude 4.0 and more, and for smaller events with the shortest hypocentral distances. Hypocentral distance is measured from S-P time using 7.09 kilometers per second of S-P time. Response spectra were calculated for all events of magnitude in the range 4.3 to 4.8, recorded at McGee Creek. 361.25-3

The average magnitude of the events is 4.5, and the aver' S-P time is 1.03 sec (average hypocentral distance 7.3 km). Horizontal-component response spectra of these events (index numbers 1,4,,5,14,32,41,,42,44,48, and 55 in Table 361.25-2) are shown in Figures 361.25-1 to 20 for 2,5, and 7 percent of critical damping. Mean and mean-plus-one standard deviation response spectra for the ensemble are given in Figures 361.25-21, 361.25-22 and 361.25-23 for 2,5, and 7 percent of critical damping. Individual response spectra were not normalized in any way in the statistical calcu-lation. The averaged spectra show response peaks at fre-quencies of approximately 9 and 15 Hz. Individiual spectra show prominant response peaks at one or both of these frequencies. Hypocentral determinations are not available for all o'f the events recorded at McGee Creek. In order to be infor-mative about hypocentral determinations, we compare in Figure 361.25-24 and Table 361.25-3 our master-event loca-tions with hypocenters determined by Archuleta et al. (1981: personal communication, HYPO output dated October 30, 14:03 P.S.T.) for all 13 events in common. Average focal depths for the two sets of hypocenters are very similar: 5.14 km and 5.13 km respectively. However, the solutions of Ar-chuleta et al. show a greater range of depths, with a calculated ' standard deviation' of 3.16 km as compared with 1.94 km. 361.25-4

r Shear wave corner frequencies meacured from Fourier spectra of the horizontal components at McGee Creek are plotted against seismic moment in Figure 361.25-25. Synthe-tic Richter magnitudes in Figure 361.25-26 plot with nearly unit slope against the logarithm of seismic moment. This result is to be expected because both momt.t and Richter magnitude are determined in the displacement-flat portion of the speJtrum for these earthquakes, as their corner frequen-cies are approximately 10 Hz. The Mammoth Lakes earthquakes occurred at considerably greater depths, and were recorded at considerably greater hypocentral distances than the RIS events recorded by the USGS accelerograph on the Monticello Dam abutment. The Mammoth Lakes events represent the release at normal focal depths of relatively rapidly-accumulating tectonic strain', and can not be considered representative of shallow RIS activity at Monticello Reservoir. B. Influence of propagation effects on McGee Creek Spectra while the McGee Creek site may be geologically the most similar of the Mammoth Lakes recording sites to the Summer site, there is evidence for a site-specific propagation effeet that would not be observed. at the Summer site. As noted above, most but not all of the McGee Creek response spectra show peaks at approximately 9 and 15 Hz. One explanation for this effect is modal response of the glacial moraine near whose edge the site is located. However, this does not explain why some of the McGee Creek records are 361.25-5

~ very simple. Nn alternative explanation is that the reson-ance observed for some events is a path (waveguide) effect, due to the presence of a fault or contact zone in the underlying bedrock. The bedrock under the site consists of faulted, folded, metamorphosed Ordovician rocks intruded by granitic batholith. Examples of simple and complex displacement seismograms are shown in Figures 361.25-27 and 361.25-28. These wideband (0.1 to 50 Hz) seismograms are for the earthquakes of May 26 at 19:25 U.T.C. and May 30 at 18:24 U.T.C. Response spectra for these events are shown in Figur.es 361.25-7,8 and 361.25-11,12. Displacement seismograms of the 18:24 event.(Figure 361.25-28) show pronounced resonance following the P and S arrivals. By contrast the 19:25 records (Figure 361.25-27) are exceedingly simple. Figur'e 361.25-29 compares the observed displacement record, north component, with a synthetic displacement seismogram computed for a point dislocation in an elastic halfspace. For this event there is evidently no anomalous path or site effect. Therefore, the most satisfactory explanation for the reson-ance observed in some of the records is a directionally dependent waveguide effect. C. Comparison of spectra of Monticello and Mammoth Lakes earthquakes of similar magnitude recorded at similar distances. At Mammoth Lakes, S-P times read reliably from wideband displacement seismograms indicate that none of the hundreds of events was recorded by the wideband instruments at a 351.25-6

range of less tEan 2.5 km. At Monticello Reservoir, useable ~ accelerograms have been recorded on the dam, abutment only for earthquakes with foci within approximately 1 km. Thus it is not possible to, compare spectra of earthquzkes record-ed at a similar distance range at the two sites. D. Variation of spectral shape with magnitude. Response spectra have not been prepared for Mammoth Lakes events over a wide range of magnitude. A convenient illustration of the variation of spectral shape with magni-tude is shown in Figure 361.25-25, where corner frequencies of shear waves recorded on horizontal components at McGee Creek are plotted against seismic moment. Another indica-tion concerning the spectral shape variation is provided by the observed dependence of-peak ground acceleration op seismic moment (Figures 361.25-31 to 34). E. Effect of low-pass filtering on computed peak ground accelerations. Accelerograms were computed from the wideband displace-ment seismograms by removing the system response and differ-i entiating twice. In order to minimize aliasing effects near the Nyquist frequency (50 Hz), the records were filtered l l with an'8-pole Butterworth filter (a minimum phase, causal, l realizable filter). A filter frequency of 25 Hz was used for all records. This frequency was chosen after conducting I ( a study to determine the effect of varying the filter i l frequency. Table 361.25-4 shows peak accelerations computed i for the earthquake of 10:25 U.T.C., May 26, 1980, recorded 361.25-7 l

~ at McGee Creek, for filter' frequencies of 1 0,1 5,2'5, and 30 Hz. Computed peak accelerations are insensitive to filter frequency for frequencies above about 20 Hz. This is as expected be,cause the peak acelerations occur near the corner frequencies (n 10 15 Hz). At higher frequencies the response spectral acceleration is determined largely by the peak ground acceleration. Thus the low-pass filtering that was required for double-differentiating the wideband dis-placement seismograms has negligible effect on high-fre-quency response spectral accelerations. F. Comparison of Mammoth Lakes spectra at different record-ing sites. A convenient way to compare spectra of earthquakes recorded at dif ferent sites in the vicinity of Mammoth Lakes ~ is to compare their shear wave corner frequencies. Figure 361.25-30 shows horizontal-component shear wave corner frequencies as a function of seismic moment for the four sites occupied by wideband displacement seismographs. The McGee Creek site shows corner frequencies consistantly higher than at the other sites. This effect is in large part attributable to significant seismic absorption for all sites except McGee Creek. The apparent corner frequencies at the other sites are not revesentative of the earth-quake source spectra, reflecting instead the effects of absorption. Peak accelerations at the four sites exhibit the same effect. Figures 361.25-31 to 34 show peak horizontal ground acceleration as a function of seismic moment for Whitmore i 361.25-8

Hot Springs, Rock Creek, Mammoth Ranger Station, and M ee Creek. These figures are not directly comparable because of differences in hypocentral distances: these are shown in Figures 361,.25-35 to 3,8. Index numbers in Figures 361.25-31 to 34 correspond with those in Figures 361.25-35 to 38, respectively. Allowing for the fact that McGee Creek is closer to the source region than are the other sites, it is evident that peak horizontal accelerations recorded at McGee Creek are significantly higher than those recorded elsewhere. At frequencies of approximately 1 Hz, there is no significant difference in motion amplitude between the four sites. This can be seen by comparing synthetic Richter magnitudes determined at each site with Berkeley Richter magnitudes (Figure 361.25-39). At all sites, synthetic ~ Richter magnitude is a good estimator of Berkeley magni-tude. Thus earthquake spectra at the four sites differ only at frequencies greater than 1 Hz. G. Figure 361.25-40 compares 50th and 84th percentile response spectra for M 4.5 Mammoth Lakes earthquakes recorded at McGee Creek with the 84th percentile response spectrum for a hypothetical M 4.5 RIS event, and with the SSE spectrum. All spectra are for 5% critical damping. Comparing at the 84th percentile level, the McGee Creek spectrum exceeds the hypothetical RIS spectrum in the bands 7-10 hz and 12-20 hz, and f alls below the hypothetical RIS spectrum for frequencies less than 7 hz and greater than 20 hz. The spectral peaks appear to be due to a directionally-dependent waveguide effect evident at McGee Creek; these 361.25-9

spectral peaks are not transferable to the Virgil C. Summer site. The 84th percentile McGee Creek spectrum exceeds the SSE spectr6m - for freq'uencies above 7 Hz. The McGee Creek spectrum differs from the SSE spectrum in representing a near-field rather than a far-field event. S 4 361.25-10
