Figure 1. (a) Location map of Potrero Canyon with basic geology (from Winterer and Durham, 1962), ground cracks mapped by Rymer et al. (1995), the seismic profile from Catchings et al. (1998), cross sections EE' and FF' of Winterer and Durham (1962) and 6d of Yeats et al. (1994), and boreholes from Holzer et al. (1999) and Gibbs et al. (2000). Black dots show locations of wells described by Winterer and Durham (1962). (b) Close-up view of Figure 1a showing the locations of our seismic profile, boreholes (pot 1-12) from Holzer et al. (1999), a borehole (pot 3) from Gibbs et al. (2000), an axial fault inferred by Winterer and Durham (1962), surface cracks mapped by Rymer et al. (1995), and imaged faults.

Figure 2. Geologic map (from Proctor, 1968) of the Desert Hot Springs (DHS) area showing the locations (bold black lines) of our DHS seismic profile (this study), an area of near-surface fault mapping along Mountain View Road (Rymer et al., personal commun., 2008), and a seismic profile (R–DHS) along Long Canyon Road (Rymer et al., personal commun., 2008). Mission Creek fault-a and Mission Creek fault-b refer to the two mapped traces of the Mission Creek fault by Proctor (1968). The third mapped fault that crosses the DHS seismic profile is the Miracle Hill fault. The Banning fault is located in the lower left corner of the map. The box shows the approximate area of the photograph shown in Figure 3.

Figure 1. Location map of the northern Coachella Valley area with major faults, cities, and the DHS seismic profile (short black line) discussed in this article (map from Rymer, 2000). AA' and BB' refer to cross sections shown in Figure 9. Banning fault (BF), Desert Hot Springs (DHS), East Wide Canyon fault (EWCF), Garnet Hill fault (GHF), Long Canyon fault (LCF), Mission Creek fault (MCF), Pinto Mountain fault (PMF), and San Andreas fault (SAF). Asterisks depict the epicenters of the 1948 DHS and the 1986 North Palm Springs (NPS) earthquakes (Nicholson, 1986). Quaternary alluvium shown in white, Pliocene and Pleistocene stratified rock shown in dark gray, and pre-Cenozoic crystalline rocks, shown in light gray. The dotted box shows location of the map in Figure 2.

Figure 3. Right-lateral component of triggered slip as a function of distance along San Andreas fault. A, Triggered slip in 1968 (from Allen et al., 1972); B, triggered slip in 1979 (from Sieh, 1982); C, triggered slip in 1986 (from Williams et al., 1988) (slip in Indio Hills not shown); D, triggered slip in 1992 (from Rymer, 2000) (slip in Indio Hills not shown); E, triggered slip in 1999. Distance scale along fault is relative to intersection of Thousand Palms Road and the San Andreas fault (see Fig. 1). Wide horizontal arrow marks direction of rupture for individual earthquakes; seismic waves from the 1968 Borrego Mountain earthquake arrived approximately normal to the San Andreas fault and thus no rupture direction is shown for that event. Slip measured on creepmeters not included in these plots. Caltech measurement arrays and creepmeters, some of which are now inactive, located at: Red Canyon, North Shore, Mecca Beach, and Salt Creek (Louie et al., 1985; McGill et al., 1989).

Figure 17. Summary of dates of paleoseismic earthquakes at sites along the southern San Andreas fault. Data are from the following sources: Pallett Creek (Sieh et al., 1989); Wrightwood (Fumal et al., 1993); Pitman Canyon (Seitz et al., 1997); City Creek (McGill et al., 1998); Plunge Creek (this article), Burro Flats (Yule and Howland, 2001); Cabezon (Yule et al., 2001) Thousand Palms (Rymer and Fumal, 1996, Yule et al., 2001); Indio (Sieh, 1986). Filled squares show best estimates of ages of faulting events at each site. Horizontal lines show one possible correlation of earthquake ruptures across multiple sites. The color of the filled square for each faulting event at a site indicates which through-going earthquake rupture it is associated with in this interpretation. Other correlations are also possible.

Figure 2. Shear-wave splitting measurements from the 2003 SAFOD array. Station locations are indicated by gray triangles, and the SAF is plotted as a solid line. Bars are oriented parallel to the fast direction and scaled by the delay time. (A) Splitting results plotted on earthquake epicenter. (B) Splitting results plotted on station location. Surface trace in Figure 2B is from mapping by Rymer et al. (2006).

Figure 4. Rose diagrams giving a polar histogram of the fast orientations from 2003. Fast directions are grouped by station location. Groups A (1–6) are splitting measurements from the cross-fault array, and Group B is results from the along-fault array. Gray rectangle shows the reduced velocity fault zone as determined by Li et al. (2006). Plotted fault trace is mapping by Rymer et al. (2006).

Figure 1. Map of the Parkfield segment of the San Andreas Fault. Stations used in the inversion are represented by the following: normal triangles, USGS stations; inverted triangles, CGS stations. Red star, 2004 Parkfield epicenter; Light blue star, 1992, 1934, and 1966 colocated epicenters; blue line, modeled fault profile; gray dots, aftershocks located by Thurber et al. (2006). Also shown is the San A $n$ dreas Fault trace (brown) and regions where postseismic surface slip occurred (red) as mapped by Rymer et al. (2006). The inset map of California shows the locations of the 2004 Parkfield epicenter (red star) and 1983 Coalinga epicenter (green star).

Figure 1. Location of the seven USGS absolute magnetometer sites relative to the epicenter (large star) and rupture (thick box with darkest section showing the greatest slip) of the 28 September, 2004 Parkfield earthquake and its subsequent aftershocks. Also shown is the University of California–Berkeley bandlimited (0.001–10 Hz) magnetic and electric (EM) field monitoring site at the northern end of the rupture (PK) and further up the fault (SAGO). Location of the San Andreas fault trace follows the work of Rymer et al. (2006). Also shown for reference are borehole strainmeter and pore pressure sites.
