... 1 act as transient asperities, and unlocked junctions may act as transient weakest links. Tentative estimates of K and G are made for each end of the Big Bend of the San Andreas fault system in Southern California.

... 2~. Geometric Incompatibility for a System of Faults with Multiple Junctions We consider here the case of rigid nonrotating blocks, which is analytically simpler than the general case and can be of independent interest.

... the value G for the region D equals the sum of the values G for all fault junctions that exist inside D at the time moment to. Application to Southern California Fault Junctions To illustrate the method suggested here, we considered a schematic representation of two nodes with multiple fault junctions around the ends of the Big Bend segment of the San Andreas fault.

... In particular, it may be one of the parameters that controls the dynamics of seismicity. Appendix: Incompatibilities for Deformable and Rotating Blocks For a system of deformable blocks, the Saint Venant compatibility condition, in the integral form, can be written as follows (ref.
