Earthquake locations and three-dimensional fault zone structure along the creeping section of the San Andreas fault near Parkfield, CA: Preparing for SAFOD
[1] Arrival-time data from 453 local earthquakes and 6 explosions at Parkfield, CA, are inverted for earthquake locations and three-dimensional Vp and Vp/Vs structure. The structure is dominated by the velocity contrast across the SAF, with the southwest side about 20–25% faster, consistent with previous studies. Nearly all the earthquakes occur almost directly beneath the fault trace. We find ...
متن کاملWeakness of the San Andreas Fault revealed by samples from the active fault zone
Understanding the strength and slip behaviour of tectonic faults is a central problem in earthquake physics and seismichazard assessment1–8. Many major faults, including the San Andreas Fault, are weak compared with the surrounding rock, but the cause of this weakness is debated1. Previous measurements of the frictional strength of San Andreas Fault rocks are too high to explain the observed we...

the use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach
abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
15 صفحه اولLow-velocity damaged structure of the San Andreas Fault at Parkfield from fault zone trapped waves
[1] We used dense linear seismic arrays across and along the San Andreas Fault (SAF) at Parkfield, California to record fault zone trapped waves generated by explosions and microearthquakes in 2002. Prominent trapped waves appeared at stations close to the SAF main fault trace while some energy was trapped in the north strand at the array site. Observations and 3-D finitedifference simulations ...
