Laboratory results indicating complex and potentially unstable frictional behavior of smectite clay

  author={Demian and M.. and Saffer and Kevin M. Frye and Chris Marone Karen Mair},
A central problem in explaining the apparent weakness of the San Andreas and other plate boundary faults has been identifying candidate fault zone materials that are both weak and capable of hosting earthquake-like unstable rupture. Our results demonstrate that smectite clay can be both weak and velocity weakening at low normal stress (<30 MPa). Our data are consistent with previous work, which has focused on higher normal stress conditions (50 MPa and greater) and found only velocity… CONTINUE READING
