Prior to the Oroville Earthquake, Butte County was assumed to be relatively safe from earthquake d4nage. A map published. by Jennings (1975); shows only one fault iii Butte County having historic movement within the last. 200 years. That fault is located approximately 9.4 miles southeast of Oroville between Wynadotte and Bangor. Figure l shows the location of the Cleveland Hill Fault, which was responsible for the 1975 Oroville Earthquake: ` Y 4`y � 2 7 3, In 1963, Burnett published a report entitled Fracture Traces in the Tuscan Formation Northern California, which was a forerunner to the publication of the 'Geologic Map of the Chico Mon cline and Nort'rteastern Part of the Sabramento Valley, by Har,Wood' Helley and Doukas in 1981. The Cleveland Hill Fault (OrW lle Earthquake) and the map of the Chico Monocline suggested a northwest trending system of potentially active faultsand fractures crossing central Butte County. Burnett (1963) used aerial photographs to initially delineate fract%re traces within the Tuscan Formation because they are generally not visible from ground level. In this study, aerial photographs were used to initially locate faults or fractures which were later identified in the field whenever possible. For the purposes, > of this report, a fracture trace or lineament is a small displacement, linear feature consisting of topographic vegetation or soil alignments visib"Le prim" an aerial photos. Such. features are rarely continuous foo :once of greater than one mile. Fracture traces are composed of many hundreds or thousands ot" fractures while faults are more discrete, having lengths, greater thorn a mile and displaying measurable displacement. Tt' Office of Science and Technology, in their 1970 report entitled Earthquake Hazard Reduction, state, 'Maps that :delineate relative kinds and degrees of geologic hazards are as yet rare and no fully satisfactory map of earthquake geologic hazards' is available for any urban area: it is realized that such maps prepared in the near future will be little more than crude it 4. approximations and continuing dacisions will have to be made regardirg their detail and scale." There are threeublished seismic risk maps from which p p it is possible to estimate maximum earthquake intensities for Butte County. These maps shoal' Modified Mercalli (M.M.) Intensities of VI, MY and. VI or VII respectively for Butte County. The .maps suggest that an intensity of 6.5 might be appropriate for Butte County. Table 1 6hows the damage assessment criterion for establishing M.M. intensities. Caution. should be exercised in using small scale regionalization maps covering large areas because as Richter (1959); states, "They should serve as general index maps from which the engineer or planning authority should pass to micro -regionalization maps for localities where constructionis"intended. The three aforementioned maps are not completely satisfactory because they are not generalized from more detailed maps. c.' TABLE I Modified Mercalli Earthquake Intensity Scale VIII.

San. Joaquin Valleys The Foothill Fault system is not comparable to the fracture system within the Chico Monocline even though their strikes appear similar at some map scales Some of the major differences between the two systems include: 11 i The faultsinthe Foothill System have a more north -south trend than the trend for fractures, tahich delineate the anis of the Chico Monoeline. 2.

(approximately 18.109 acres) is located in the northeast�' 1/4 of Section 10, T18N, R4E. The average elevation of the property is approximately 350 feet above mean sea level.. The property is tentatively divided into three approximately 5.0 acre parcels. A prominent drainage channel or swale bisects the property in a general northeast -southwest direction. There are +.,,wo reservoirs currently occupying the western half of the swale. Property jtetbacks should be required for leach --lines or buildings from the high-`wator, level a„zocda.ted with each reservoir. There are two major depressions within the pkb petty where presumably gravels were ekcavated One small. depression in the northeast corner of the parcel and another on top of the ridge in the southeast corner of the property. Setbacks should also be established for these two depressions. GEOLOGY riqurdi &''shows the geology in the vicinity of the Pendergast j Parceli Only two geologic units are encountered, within the •boundaries of the parcel. The two geologic units are Arc Complex .Rocks (Ya) and Gravels (Cg): Are complex Rocks (LTA v) are dark to light blue --green, poorly foliated, metamorphosed; andesitic to basaltic agglomerates, tuff breccias and tuffs. Foliations southwest of. the parcel strikd N20W, and dip approximately 72 degrees to the east; see figure 6• Isolated outcrops of arc' com1.ex rocks -s are encountered in the swale crossing the center of Al 14 the property. Th arc complex rocky are unconformably overlain by rath' � p er' tl.at--lylbi'g gravels (Cg) , see Figure 6. These gravels are composed of bedded and flat-lying conglomerate, sand and silt.The conglomerate is weakly cemented andhay a reddish-brown maty.int. ,I The pebbles and boulders are mostly derived from local metamorphic, intrusive and volcanic rocks Sand and silt units are lens-shaped and often cross-bedded. North of the parcel the conglomerates strike approximately N3OW and dip 6 degrees -to the southwest. Approximately 1/2 mile east of the property are alluvial deposits associated with Wyandotte Creek. FAULTS, FRACTURES AND LINEAMENTS No kaUltsr fractures or lineaments were observed'withiii, the boundaries of the parcel, either on aerial photographs or durinq,my site visitation on October 9, 1992. Cole '4�ffid Mciunkin (1978) mapped a concealed fault trace approximately 0.75 miles east of the property 'which is probably a riort:hward extension of the Prairie Creek fault system shown in Figure `, Ground cracking associated -with the 1975 Oroville Earthquake has been mapped approximately 2.9' miles east 4 the center boundary of `the parcel: The August l 1975 hypocenter is approx .mately i , i.5 mILe ' northwest of the ,propert:y. 1 a jar is LANDSLIDE POTENTIAL Map 3. 1, of the Safety Element of the Butte County General Plan indicates that the parcel is. located within Zone 2. Zones 1 and 2 have a landslide unit risk of none to low. i WET UNSTABLE GROUND Triere is an unlined, irrigation ditch, running parallel to the north boundary of the parcel. seepage from this unlined ditch is creating wet unstable ground in. the northwest corner of the property. A possible mitigation measure might be to line the ditch or install a pipeline along the north boundary of the Property., No Leach -lines or buildings should be located within this saturated unstable area. ilPANBIVE SOILS, EROSION AND LIQbEFACTXON POTENTIAL The safety Element Daps in the Butte County General plan suggest that the erosion potential within the parcel is slight to moderate. Generally, the steeper gravelly areas not Underlain by bedrock have higher erosion g- potentials According to the Butte y , liquefaction otent Count General Plan, the 7.i ue p gal within the parcel is generally low. The county plan .indicates that the soils within the parcel have generallyhigh i h e pansivty Most of ttid parcel is underlain by weakly cemented conglomerates and the soils observed were than and discontinuous;. v I 16 ESTIMATED SEISMId HAZARD FOR THE PENDERGAST PROVERTY The literature' and data suggest that Butte County is Within an area of low 4to moderate earthquake intensities which have relatively long recurrence intervals and are accompanied by minor G ground rupture and offset. The California Department of Water Resources (1979) concludes that there is 'nothing in their study which would indicate a. Richter Magnitude for another oroville-T3riae Earthquake greater,than 6.5 '(the August, 1975 magnitude was 5.7) For comparison purposes, the 1906 San Francisco Earthquake had a Richter Magnitude of 8.3 A magnitude of G. 5 would only be observednear the epicenter. Figure 7 shows a preliminary isoseismal map for the. August 1, 1975 Orov lle Earthquake The California Department of WaterResources (1979), suggest that the' maximum offset. from another Oroville-Type 'Earthquake would generally be 2A inches in the vertical: direction and 1.0 inch in the horizontal dird.dtion. The question of seismic hazard in the Chico-Oroville area essentially becomes one of estimating the degree of attenuation with distance from the Cleveland Hill or Swain Ravine 'Fault System for an estimated maximum Richter Magnitude of 6.5 Most techniques for estimating rock acceleration as a function Of distance from a fault plane or earthquake epicenter utilize data and 'methodologies 6itilar to those developed by Schnabel and Seed (1973): Acceleration data obtained by 'the California Division of Mines and Geology (1975) are shown in Figures 8A and 8B. Figure 8B u �. � L_ 1$ ' � ,' � „_ 4 . � ��. y ,.� K E _. -a lE h y, �x 14 s;howig that the rock accelerations in the Oroville-Chico area are less than those infers ed from the regional models of Schnabel and sees! (1973) Figure 9 from Donovan (1973) provides a 'method for estimating 'I Maximum rock accelerations at the Pendergast property. if the Cleveland Hill Fault, locatedapproximately 2.9 miles east of the center of the property was to become active in a sfashion similar Ito the Orovi.11e Earthquake of 1975, the energy center would be 5.5 miles or 9.9 kilometers beneath the property. According to Figure 9, if we assume a distance of 8.9 kilometers to the focal point, the estimated maximum rock acceleration at the center of the parcel would be 400-630 cm/8eC2 or 0.41 to 0.64 g's. Rock accelerations greater than 0,68 g's could be experienced 'if a high intensity earthquake occurred ata shallower depthalongthe recently active Cleveland Hill Fault Plane. Estimations of ground motions from earthquakes is an inexact science. The various physical processes that operate during an earthquake are not well understood and statistical distributions for many empirical relations used to estimate -.1totind motions are not adequately defifnec,,-iTo compensate for thA abovei upper boundary values (mean +1 standard deviation) for peak ground acceleration at the Pendergast site were included because of uncertainties involved in estimating regional seismic attenuation and local ground responseto a given earthquake intensity.

Data used by Donovan (1973) to construct the curves shoran in Figure 9 include the 1971 San Fernando Earthquake which had a magnitude of 6.6 which is near the maximum intensity of 6.5 estimated for a .future Oroville Earthquake; A maximum acceleration of 0.64 g's represents a reasonable estimate based upon current information and the state of the art for the science of seismology. A maximum rock acceleration of'0.64 g's is conservative because it is based upon themean plus one standard deviation curve shown in figure '10 and the energy center was located on the recently active Cleveland Hill Fault Plane adjacent to the property. With observed ground cracking within 2.9 miles east of the proporty, there is a possibility that some minor ground cracking might occur 'Within the property boundaries during an earthquake A partial mitigation of the potential hazard from the effects of ground motions resulting from earthquakes would be provided by constructing buildings resistant to lateral forces as outlined by the, uniform Building Code.
