The 1954 Rainbow Mountain‐Fairview Peak‐Dixie Valley, Nevada, sequence produced the most extensive pattern of surface faults in the intermountain region in historic time. Five earthquakes of M>6.0 occurred during the first 6 months of the sequence, including the December 16, 1954, Fairview Peak (M = 7.1) and Dixie Valley (M = 6.8) earthquakes. Three 5.5≤M≤6.5 earthquakes occurred in the region in 1959, but none exhibited surface faulting. The results of the modeling suggest that the M>6.5 earthquakes of this sequence are complex events best fit by multiple source‐time functions. Although the observed surface displacements for the July and August 1954 events showed only dip‐slip motion, the fault plane solutions and waveform modeling suggest the earthquakes had significant components of right‐lateral strike‐slip motion (rakes of −135° to −145°). All of the earthquakes occurred along high‐angle faults with dips of 40° to 70°. Seismic moments for individual subevents of the sequence range from 8.0 × 10 17 to 2.5 × 10 19 N m. Stress drops for the subevents, including the Fairview Peak subevents, were between 0.7 and 6.0 MPa.
