- 요약Continental strike-slip faults comprise the dominant sources of seismic hazard in California. The San Andreas fault system in particular has not experienced a major M 7 earthquake since the 1906 San Francisco earthquake, and it is estimated to have been two-to-three times longer since a major event last occurred the southern San Andreas fault (SSAF). Since no quantitative records exists for such an event, information about the factors that influence the occurrence and nature of large earthquakes on the southern San Andreas fault system must be extracted from observations during the interseismic phase, or from analogous fault systems in other parts of the world.In this dissertation, I leverage a collection of remarkable space geodetic observations of interseismic fault deformation along the San Andreas and Eastern Anatolian fault systems in order to improve understanding of the mechanical properties and behavior of large continental strike-slip faults. Chapter 1 combines modeling of interferometric synthetic aperture radar measurements of fault creep with seismic reflection analysis to demonstrate that the SSAF has a significant component of northeast dip in the shallow crust. Chapter 2 examines the kinematics of a transient slow slip event (SSE) on the Superstition Hills fault, which lies within the broader San Andreas fault system, and shows that there appears to be a characteristic pattern in which the fault accommodates shallow creep. Chapter 3 evaluates the destructive 2023 Turkyie earthquake doublet, which occurred on major continental strike-slip faults analogous to those found in southern California, and demonstrated that these earthquakes released more built-up strain than had accumulated since the preceding major M 7 earthquakes. Finally, Chapter 4 returns to the SSAF to produce models that capture complex variability in shallow creep associated with dynamic triggering from the Mw 8.2 Chiapas earthquake. Ultimately, this collection of studies demonstrates how measurements of interseismic deformation can be used to improve understanding of the fault properties that directly influence earthquake ruptures, as well as illuminates the complexity of fault slip on time scales ranging from minutes-to-millenia.
