The 28 September 2004 M 6.0 Parkfield earthquake, a long-anticipated event on the San Andreas fault, is the world’s best recorded earthquake to date, with state-of-the-art data obtained from geologic, geodetic, seismic, magnetic, and electrical [...]

Historically, the Parkfield segment has represented a transition in fault behavior along the San Andreas fault (SAF). Despite a ~33 mm/yr long-term slip rate along the SAF, slip has not been observed on the Cholame segment since the great 1857 F[...]

The Parkfield–Cholame region, 40 to 60 km southeast of Priest Valley, lies near the junction of two contrasting segments of the San Andreas fault. To the southeast is the ~350-km locked segment that had up to 9-m displacements in the 1857 earthq[...]

The 1985 prediction of a characteristic magnitude 6 Parkfield earthquake was unsuccessful, since no significant event occurred in the 95% time window (1985–1993) anywhere near Parkfield. The magnitude 6 earthquake near Parkfield in 2004 failed t[...]
