In geology, aseismic creep is measurable surface displacement along a fault in the absence of notable earthquakes. Perhaps the best known example is along the Calavaras fault in Hollister, California. Streets crossing the fault in Hollister show significant offset and several houses sitting atop the fault are notably twisted (yet inhabitable). The city attracts geologist and geology students almost weekly. There is also significant aseismic creep along the Hayward fault in and near Hayward, California.

The central segment of the San Andreas fault runs in a northwestern direction from Parkfield to Hollister.
While the southern section of the fault and the parts through Parkfield experience earthquakes, the rest of the central section of the fault exhibits a phenomenon called aseismiccreep.
This results in the fault being able to move without the need of earthquakes.
