... margin located in the Gulf of California. The numerous earthquakes which have been located in northern Baja California by the California Institute of Technology (Hileman et al., 1973) appear to be scattered across the peninsula, suggesting a broad zone of deformation (Figure 1). Until recently however...

... Sandstone polygonal cracks. Interpretations of the Permian Coconino Sandstone began primarily with the work of McKee (1934 , 1945 ) and Reiche ( 1938 ), followed later by subsequent work ( Fisher, 1961 ; Sorauf, 1962 ; Lundy, 1973 ; Elcock, 1993 ; Sumner, 1999 ; Maithel et al., 2019 , 2021...

.... The San Jacinto fault forms a major structural feature throughout southern California and is the most active, both in terms of major historical earthquakes and on-going microearthquake activity (Arabasz, et al., 1970; Cheatum and Combs, 1973).

For purposes of this study, we have assumed that the earthquake was on the Cane Spring fault. The earthquake of February 19, 1973, was located in Frenchman Flat near the Ranger...
