In this section, we briefly discuss some events of particular historical, social, or scientific significance. Although each of the 117 San Andreas fault system events in Table 6.1 merits discussion, this task is far beyond the scope of this review, and so the reader is referred to the reports by Richter (1958), Coffman and others (1982), and Townley and Allen (1939) for an introduction to many of these events. Table 6.1 also omits several historically significant events with magnitudes well below the nominal threshold of M=6 adopted here, and soit something less than a complete reference on San Andreas seismicity.
My major effort in constructing this catalog has gone into identifying and validating all reported events of M>=6. Two conspicuous omissions from Table 6.1, events that are commonly mentioned in the literature but that could not be substantiated upon further inspection, should be noted. The first is the 1852 earthquake alleged to have ruptured the Big Pine fault (for example, Jennings, 1975). Toppozada and others (1981) failed to find any evidence supporting the occurrence of a major earthquake at that time in the region. Geologic inspection of the surface trace of the fault by M.M. Clark (oral commun., 1988) similarly failed to provide evidence of any historical activity. The other deleted event appears on the seismicity map by Goter (1988) at lat 35� N., long 125� W., with an epicenter from the catalog of Abe and Nognchi (1983). Although a large (Ms=6.8) earthquake certainly took place on March 22, 1902, no evidence has been uncovered to support a location anywhere on shore in California or, for that matter, in the Western United States. The original location determined by Milne in 1903 placed the event well off the California-Oregon coast at lat 42� N., long 130� W.
