| Abstract: | Documents the spatial variation of creep rate along the Hayward fault since the 1868 earthquake. Creep (aseismic fault slip) occurs over at least 66 km and may extend over the fault‘s entire 82-km length, of which about 13 km lies underwater. Creep rate seems nearly constant over decades, but short-term variations occur. Creep rate mostly falls in the range of 3.5-6.5 mm/yr; but systematic variation occurs along strike. Subtracting surface creep rates from a long-term slip rate of 9 mm/yr gives present potential for surface slip in large earthquakes of up to 0.8 m, with an average of 0.6 m in the northern segment and 0.4 m in the southern segment. A simple hypothesis for rupture potential is presented that is compatible with historic creep rate, microseismicity distribution, and geodetic data. -from Authors |
