| We used the mean Pleistocene vertical slip rate from Johnson and others (2001), derived from onshore subsurface data. The 80 ka top of the Whidbey Formation is offset vertically by 11.9 m across the fault. We stress that this slip rate does not include possible strike-slip motion that cannot be identified from vertical offset data. Characteristic magnitude fixed at M7.5. |
