by James J. Lienkaemper and Forrest S. McFarland

Table S9. Best-Fitting Log–linear Coefficients for 6 yrs of Accumulated Slip on Alignment Arrays Following the 2004 Parkfield Earthquake

Distance from XMM4 (km)	Alignment Array		a	b
0	XMM4	Middle Mountain	1.957	5.472
8.4	PKN4	Parkfield north	5.297	5.985
9.3	PKF4	Parkfield bridge	3.586	6.716
13.2	HST4	Hearst north	2.699	7.767
17.4	KEN9	Kennedy Ranch	4.073	7.038
21.2	PGH4	Gold Hill	2.871	3.536

Slip, u(t) = a + b × log₁₀(t).
