Hi John. Any chance that the same thing could apply to the Loma Prieta quake or was it just a tad bit to small? I’m fairly sure the M=5.4 quake in August of 1998 near San Juan Bautista was the results of the Loma Prieta quake as the quake was very close to the southern end of the rupture. I’m kind of curious as to what change if any might have occurred on the parallel faults to the Loma Prieta quake.

There was a report that the creep on the Hayward fault reversed for a 7 year period after the Loma Prieta quake. Not sure if that was the entire fault or just a portion of it. Take Care…Don in creepy town

“The 1999 magnitude 7.1 Hector Mine earthquake, in the Mojave Desert near Los Angeles, damaged the fault that broke in the 7.3 magnitude Landers earthquake seven years earlier, report John Vidale, UCLA professor of earth and space sciences, and USC seismologist Yong-Gang Li, in the Jan. 30 issue of the journal Nature.”

“Vidale's research marks the first time scientists have shown that one fault has been damaged by the shaking and stress from an earthquake on a different fault, he said. The rock within approximately 100 yards of a major fault slip surface is highly fractured, and is therefore especially vulnerable to such damage, Vidale said.”
