by James J. Lienkaemper and Forrest S. McFarland

Table S8. Best-Fitting Coefficients of Modified Omori Law of Langbein (2006) for 6 yrs of Accumulated Slip on Alignment Arrays Following the 2004 Parkfield Earthquake

Distance from XMM4 (km)	Alignment Array		Tau (days)	A′	p	Offset (cm)	Notes
0	XMM4	Middle Mountain	1.00	16.10	1.10	−0.28
8.4	PKN4	Parkfield north	6.67	15.19	1.20	5.86
9.3	PKF4	Parkfield bridge	3.95	15.90	1.01	5.04
13.2	HST4	Hearst north	11.67	15.46	1.01	7.04
17.4	KEN9	Kennedy Ranch	12.52	15.61	1.10	6.61
21.2	PGH4	Gold Hill	2.78	8.42	1.01	3.63	Includes 2010 data

See the Afterslip Models section in the main article and equation (2) in the main article for definition of coefficients. Offset is inferred coseismic slip.
