Buried fault
WebThe fault is buried here, but we document a broad zone of deformation associated with the eastern strand of the fault that changes in character, along strike, across ~600 m of the river channel. Radiocarbon dates from sediment cores collected in the Sacramento River provide some minimum constraints on the age of deformation. We do not observe ... WebAcoustic Fault Pin-Pointing: The acoustic fault location method is used for pin-pointing of high resistive or intermittent faults in buried cables in which the cable is “thumped”, i.e., a series of high voltage surge pulses are sent down the cable causing the fault is break down.
