INTRODUCTION
The. Oroville Earthquake of August 1, 1575 demonstrated
the need for a ,reevaluation of ';ei!smic hazards within Bute County.
Prior to the Oroville Earthquake, Butte County was assuined to
he relatively sae from earthquake damage. A map published by
Jennings (1975) shows only one fault in Butte County .linv3,ng
historic movement within the last 200 years.. That fAL1.1t is located
approximately 3.4miles southeast of Oroville between Wynadotte aiid
Bangor. Surface fractures from that fault, later named the Cleveland
Hill Fault, resulted from the 1575 Oroville Earthquake,

(From Ildnhings, 1975
�a
In 1963 Burnett published a report entitled, Fracturo .races
in the Tuscan Formation, Northern California, which was a.toterunner
to the publication of the Geologic Map of the Chico Mollo 7llne and
Northeastern Part of the Sacramento Valley by Harwood, 11q,11by And
Doukas in 1981. The Cleveland Fault (1975 Orovill.e Rat'l:hqualce)
and the map of the Chico Monocline suggested a northweML� trending
system of potentially active faults and fractures crothy central
Butte County.
Burnett (1963) used aerial photographs to initially dolibeate
fracture traces within the Tuscan Vormation because they are
generally notvis%ble from ground Level. In this study both aerial
photographs and infra -red variscan analysis were used to initially
locate ;faults or fractures which were later identified in the
field whenever possible. For tine purposes of this report, a
fracture trace is a small displacement, linear feature consisting
of topographic vegetation or soil alignments visible primarily
on aerial photos. Such features axe rarely continuous for a
distance of greater than, one mile. Fracture traces, atecomposed
of many hundreds or thousands of fractures while faults are more
p
discre=te, having lengths greater than a mile and often display
measurable displacement.:,.
'Rhe office of Science and Technology, in their 1970 report
entitled Earthquake Hazard Reduction state, "Maps t)Ynt dileneate

approlti,mations and continuing decisions will have to be made
regarding their detail and scale."'
There are three published seismic risk maps from which it is
possible to estimate maximum earthquake intensities for Butte County.
These maps show Modified Mercalli (M.M.) Intensities pf VIt VII and
VI or VII respectively for Butte County. The maps soggest; that
an average M.M. intensity of 6.5 might be appropriate for Butte
County. Table 1. shows the damage assessment criterion :dor establish-
ing M.M. intensities.
Caution should be exercis'ed,in using small scale regio�jal,ization
maps covering Large areas because as Richter (1959) stakes,. "'They
should serve as general index ;maps from which the engineer or
planning authority should pass to microregonalization maps for
localities where construction is intended." The three forementioned
maps are not completely satisfactory because they are not generalized
,from more detailed maps. Fortunately, the Oroville Earthquake of
1975 and the accompanying aftershocks provide some additional
valuable information for the microregIonali—.tion of seismic risk
within Butte County

eastern portions of the property are underlain by Hio SlmarLville

Figure 12 shows a map of fracture traces A.00nted within
and near the property. The photo lineament approximately 1.0
mile northeast of the center of the property may be an eXtehol,oh
of the Foothill Fault System which is more prorl,'ounced south of
the city of I)roville. The two features may not be related be-
cause their dips are different. The fractures shown on Figure
12, within the property boundaries were observed on air photos,
inf-ared film and were checked in the field on June 3j 1986.
F41ractures within the property may or may not be related to the
Foothill Fault system because they appear to be west of the
general alignment of the Foothill System. Nevertheless, as a
precaubionar measure, no building should be located within 75
feet of the yellow fracture traces shown on Figure 12. All
structures should be beyond the reach of fallen power lines and/
or Lowers associated with the notLh-souLh trandiiiq power line
crossing the central portions of the property. A(Id i Liona I ly

A !?lot of all -the acceleration versus distance data from which.
the 0.70 q value was lected suggests that the 0.70 g vtAj,t:te is
indeed an outlier. It ,should be remembered, however# L-liO°
ground accelerations considerably higher than 0.67 g's
possible at the property due to the fact that the '�orlwlt;l tan
of PULuze ground motions is not an exact science. 1,910 raoLlma.t�o
of 0.67 g's merely represent a reasonable estim7Lo based uport
current information and the state of the art for the sc.i.ence
of seismology.
It should also be remembered that a rock acceleration of
0467 g's is conservative because it is based upon a hstorcal.,l.y
inactive photo lineament becoming active.

Dear Sir*.
Thank you for the opportunity to review and comment. 'upon the Potter RAvitze Shores'
Unit 2 Tentative Subdivision Map,
If approved, it is our concern that the development be clooely monitored during
the construction phases to insure that Any siltation is kept to a minimum -
The resL,ilting housing development will adversely impact the view abed of the
Potter flavine Unit of Lake Orovi.11e S.R.Ai. Loss of solitude, smoke and haze
will; be deleterious to the uniqueness of this area.
Other factors to be considered in this review are the.effortd upon the wild
turkey flocks in the area. .And the impact of septic leachin from future home.
