R. north -northwest, the faulting i,n Butte
County is also generally in this direction.
Most Sierra Nevada faults are a comb nation
of strike slip and thrust movements. 3
The ohly known active fault ih Butte '
county is the Cleveland Hill fault
approx IMatelY Ox-, southeast of. 0roV'1114e
- and twenty miles south of the project
site. The fault is thought to be
approximately ten miles long,4 I't was
moV:ement of this fault which produced
the OroVille ear'thquak;e )f August 1, 1975,
The, fault nearest the project site is;,
the Big 8ehd faUT,t,r the inferred Westerh
