Figure 53--Stress and deformation indicators. Borehole breakout direction and some focal mechanisms were taken from Zoback and Zoback (1991). Remaining focal mechanisms are from Mulder (1995) and Pacific Northwest Seismic Network (Qamar and Ludwin, 1992). Dikes in the Mt. Rainier are adapted from T. Sisson (1998, writ. comm.); Fold axis directions inferred from Goldfinger et al. (1991) and McCrory (1996,1997). GPS velocities from Qamar et al. (1998).
