[c [ Abstract
'_t w
,l This report summarizes and interprets the geologie data presented
- i. \
C_' .
in previous reports by the Geological Surrey. These data bear on the F..
5i] effect of large magnitude earthquakes on the foundation of the, proposed L.1 '
nuclear power plant on Bodega Head, California.
Q The crucial geologic problem at the site involves an estimate of the probability of a suddan permanent displacement, by rupturing, of the foun-dation rock of the reactor during an earthquake. Any such prediction
((
must be based to a great extent on experience in earthquake-affected B?r regions; it can be made only with a relatively low degree of confidence LZ e
because geologic knowledge of the phannmana being evaluated is incomplete,
{ and in some instances rudimentary.
P I' '
An upper limit on the probability of faulting is set by the probabil-f-
b ity of occurrence of severe earthquakes (Richter magnitude 8.0 and above)
~ ~
g on the San Andreas fault. This has been ertimated by several highly r
j qualified seismologists to be on the order of one or two per century.
The Bodega Head site is almost certain to experience one severe earthquake in the next W years, the assumed lifetime ofet.be plant.

The principal hazards to the plant from such a seismic event' are twofolds (1)shakingofthegroundduetosciamicwavepropagation,
- and (2) possible displacement of the foundation rocks due to faulting. - l
, The hazard due to ahairing is being investigated by others, including the Seismology Division, U. 8. Coast and Geodetic Survey. prediction -l l' b ; as of possible displacement must be based largely on the distribution and I characteristics of the surface faulting produced by the 1906 earthquake
+) ,
M E
and to a lesser extent on the distribution of faults in the excavation I 3/
Efh, for the reactor and on Bodega Head as a whole. The evidence is not ps
, adequate to suggest more than a general statement of probabilities.
4 ! The site is approximately 1,000 feet west of tbs vest edgs of the r-g SanAndreasfaultzone,whichisapproximatelyl}milesvidehere. The b main surface ruptum during the 1906 earthquake 7,ock place on the east j p.3 side of the scoe and had a horizontal displacement of 10-20 feet. '
p Throughout Bodega Head, faults and joints are cosmon in the granitic r;<
h rocks with the largest ones trending northwest, northeast, and east.
4 I .
95 l At the site, a principal structure is the Shaft fault, named from its W ,
g- ,
erposures in the shaft excavated for the reactor. This fault, one of r' ,
many tectonic faults in the granitic rock, is the only one that has e i
~.
e D been traced downward from the surface through Pleistocene sediments into the underlying granitic rocks. It strikes N. 400 E. and has been f e j t aced on the surface a. total of about 230 feet. ma mart == measured i displacement in the sediments is 14 inches vertica5.ly and in the granitic rocks is at least 24 feet horizontally.

E i
$, Surface ruptures created during the 1906 earthquake have been - l c.--
[5 er described at many localities outside of the San Andreas fault zone i
'(Lawsonetal,1908). The record of these events provides important k(
p;;,
clues for predicting future earthquake phencuena on Bodega Head. The G .
C'r character of the measured ruptures at the'se localities indicates that '
Le e ..
y sans of the faults parallal the San Andreas, others intersect it at w , '
f acute angles, and still others are nearly normal to it.
.! l The principal observations of ruptures outside the main fault zone yi i after the 1906 earthquake were made at the Point Reyes Peninsula,.the
. San Francisco Paninsula, and the Santa Crus Mountains; undoubtedly
- l. faulting occurred in large areas alsewhere which were not studied.

No' investigation was made at Bodega Head. Nevertheless, the. data, ;
particularly that from the Point Reyes Peninsula, can be used as a very general guide to the expectancy of fault displacements' at j I
various distances 1 rom the main fault zone during some future earthquake.
)
In general, the 1906 bedrock ruptures were reported by G. K. Gilbert
' r to increase in abundance and amount of displacement towards the San -
, b t . .
- I Andreas fault zone. They occurred in the Point Reyes area as far as q
.' f p,2 10 miles west of the San Andreas sone, but the ones farthest out were
~_ i barely discernible. At distances of a mile, horizontal displacement j m l
{ of 2 to 6 inches was observed. At Inverness, about 2,000 feet from the :
j Ed. i ,
p' '
sone a horizontal displacement of 2d feet was measuzwd. l b The geologic setting of Bodega Head is similar to that of Point I W l m Reyes Peninsula. The granitic rocks of both areas bound the western a
b.f.' edge of the San Andreas sone and both bedrock masses are pervasively
{%~ _-
fractured and faulted. Topographic differences between the two areas -j h R@
are pronounced. Point Reyes is higher, thereby intercepting more rainfall; it is larger and contains a better-defined system of stream
{ ..
hc drainage. The topographic differences are considered to be of secondary g-
[.. importance insofar as predicting future faults is concerned. The two I. areas would be expected to react similarly to.the stresses culminating.
