A possible exception is a "fault:, actii►ity unknown" that at its northernmost extent comes, within O„l ori of the east end of the Miller property. if its trend continues northerly be- yond what is shown on the map, it might pass through the 'northeast- ernmost corner. `there is, however., no evidence that the trend continues northerly undisturbed (6,g. , it might pass along Wyan- dotte Creek) , no evidence that it continues at all, no evidence that it has experienced fault movement ;in the geologically -recent past, acid no evidence that it is even a fault. Recent geological mapping of this region by Department of Water, Resources (1979) does not indicate a fault along this trend. Plotting of locations of ground cracking on the enclosed map of the Palermo region shows that no ground cracking occurred in 1975 closer than a few hundred feet from the property, and no trend deduced from the pattern of cracking crosses it. Lineaments observed on black -and -white air photos consist of aligned vegetation and trend parallel or su.bparallel with regional trends of bedding in metavoidani,c reek. Aligned vegetation on metavolcanic rock: south of the property appears tobe following lows soil -filled areas between discontinuous lihea r outcrops of rock; the cause of similar, trends on conglomerate is not obvious, but could be related to distribution of groundwater controlled in Lydon page fo January 9, 1985 turn by trends of bedding in buried metavolcanic rock. DESCRIPTION OF SEISMIC. HAZARD In August 1975, a magnitude 5.7 earthquake occurred, along with numerous fore- and aftershocks its epicenter was located about 1..5 mi west of the Miller property. Ground breaking occurred near Palermo and discontinuously over a distance of 7 mi within the Swain Ravine lineament, a Few miles to the east. Maximum vertical displacement was about 2 inches and horizontal displacement about 1 inch. Structural damage within a few mikes of the epicenter in- cluded fallen plaster, broken Windows, toppled chimneys, houses shifted off their foundations, and settling or movement of found- ations and approaches to small bridges. Because of concern over the Auburn dam, the earthquakb trig- gered extensive study by private and governmental organizations into the seismicity of the Sierran foothills. Conclusions, summar- ized by,Divisioh of Mines and Geology Staff (1979), are that a maximum credible earthquake having a magnitude of 6.5 should be Coitsic Bred possible anywhere in the Foothills Fault System; Department of Water uescurces (1979) p. 79) concluded that the potent;al for future earthquakes and ground rupture in the Oroville area is greatest, along the Swain Ravine lineament, north and south of the part ruptured in 1975. Toppozada and Morrison (1982) con- eluded that the timing and magnitudes of earthquakes from 1975 through 1981 suggest that the 1975 rupture; zone is being Progress- ively relieved of stir„ass, but that stress has not necessarily been relieved outside that zone. Because (1) the Prairie Creek linearnent merges with a linea- ment containing an active fault► (2') the "Palermo crack zone” formed along Al linear extension of the trend of the Prairie Creek lineament, and (3) small ea rthquakaes have occurred along the linea meant, , the Prairie Creek lineament zone should be regarded as capable of the same kind of activity as occurred along the Swain RaVine lineament zone in 1975 (inept'. Water Resour:'ces 1979-) Folovinq the 1975 earthquake, a Consulting board for Earth quAk'e Analysis recoMmended ( Dept.

The General Plan concludes that a maximum intensity of VIII+ should be anticipated for future earth, quakes in most of eastern Butte County; this is in general agree- ment with the expectation of a magnitude 6.5 earthquake. The expected loss among non-resistant mobile homes from such an earth- quake would average 12 percent, according to the curve of Stein= . brugge et al.; loss from injury in mobile homes ;is generally similar to that experienced in wood -frame dwellings.
