Spatially variable fault friction derived from dynamic modeling of aseismic afterslip due to the 2004 Park fi eld earthquake

Abstract

[1] We investigate fault friction from dynamic modeling of fault slip prior to and following the Mw 6.0 earthquake which ruptured the Parkfield segment of the San Andreas Fault in 2004. The dynamic modeling assumes a purely rate-strengthening friction law, with a logarithmic dependency on sliding rate: m 1⁄4 m þ a b ð Þ ln v v . The initial state of stress… (More)
