Figure 3. The rupture areas of California’s three largest transform earthquakes — the 1857 and 1906 San Andreas shocks, and the 1872 Owens Valley shock — are all seismicity holes (shaded in purple), evidence that these faults are far from static failure today. The first panel is “complete” (meaning that all shocks greater than magnitude 6 have been reliably detected) for California. The second is “complete” worldwide for earthquakes greater than or equal to magnitude 4.4 since 1994, so this map could be compared to a ruptured transform anywhere in the world.
