We observe fault zone head waves (FZHW) that are generated by and propagate along a roughly 80 km section of the Hayward fault in the San Francisco Bay area. Moveout values between the arrival times of FZHW and direct P waves are used to obtain average P-wave velocity contrasts across different sections of the fault. The results are based on wavefo...

Issued as final report / The San Andreas Fault Observatory at Depth (SAFOD) has yielded significant new insights into the nature of the San Andreas fault (SAF). In particular, the recovery of ~ 40 meters of core containing two meters-thick zones of fault gouge and adjacent zones of damage and alteration provides a unique opportunity to characterize...

The spatial patterns of bimaterial interfaces along the Parkfield section of the San Andreas Fault (SAF) and central section of the Calaveras Fault are systematically investigated with large data sets of near-fault waveforms. Different from the usage of direct P and S waves in traditional tomographic studies, a particular seismic phase named fault ...
