Fig. 29.14. Earthquake shocks and faults of California and western Nevada. The faults are 

 those generally considered to have suffered late Pleistocene or Recent activity. Earthquakes 

 compiled from Byerly (1940), Gutenberg (1941), Byerly and Wilson (1936, 1937), and tables 

 supplied by C. F. Richter. Earthquakes above the magntiude of 5 are shown in large dots, 

 those below by small. In the compilations some earthquakes may have been shown twice 

 because of overlapping and discrepancies in location assignments. 



Fig. 29.15. Index map of Washington and Oregon. Coast Ranges are vertically dashed; the 

 extensive volcanic fields are unruled; and the pre-Tertiary rocks, mostly Nevadan complex 

 are cross-ruled.
