This book was released on 2007 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: Repeating earthquakes (REs) are sequences of events that have nearly identical waveforms and are interpreted to represent fault asperities driven to failure by loading from aseismic creep on the surrounding fault surface at depth. We investigate the occurrence of these REs along faults in central California to determine which faults exhibit creep and the spatio-temporal distribution of this creep. At the juncture of the San Andreas and southern Calaveras-Paicines faults, both faults as well as a smaller secondary fault, the Quien Sabe fault, are observed to produce REs over the observation period of March 1984-May 2005. REs in this area reflect a heterogeneous creep distribution along the fault plane with significant variations in time. Cumulative slip over the observation period at individual sequence locations is determined to range from 5.5-58.2 cm on the San Andreas fault, 4.8-14.1 cm on the southern Calaveras-Paicines fault, and 4.9-24.8 cm on the Quien Sabe fault. Creep at depth appears to mimic the behaviors seen of creep on the surface in that evidence of steady slip, triggered slip, and episodic slip phenomena are also observed in the RE sequences. For comparison, we investigate the occurrence of REs west of the San Andreas fault within the southern Coast Range. Events within these RE sequences only occurred minutes to weeks apart from each other and then did not repeat again over the observation period, suggesting that REs in this area are not produced by steady aseismic creep of the surrounding fault surface.
Book Synopsis Observations and Modeling of Shallow Fault Creep Along the San Andreas Fault System by : Meng Wei
Download or read book Observations and Modeling of Shallow Fault Creep Along the San Andreas Fault System written by Meng Wei and published by . This book was released on 2011 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation focuses on observations and modeling of fault creep in California aiming to understand the relationship between creep and earthquakes and assess the earthquake hazards in California. Chapter 1 gives an introduction of fault creep research in California, geodetic methods used to measure fault creep, and mechanism of fault creep. Chapter 2 documents an investigate on a creep event on the Supersitition Hills Fault in Southern California and the spatial and temporal variations in slip history between 1992 and 2008 using ERS, and Envisat Satellite data confirming that the fault creep is confined within the sediments layer and is probably due to the low normal stress in unconsolidated sediments. Chapter 3 presents a study on triggered slip on faults in the Salton Trough by the 2010 El Mayor-Cucapah Mw 7.2 earthquake. Chapter 4 compiles geodetic data and investigates the relationship between shallow stress accumulating rate and creep rate. Chapter 5 and 6 explores two technical projects related to fault creep observations in California. Chapter 5 analyzes decorrelation of L-band and C-band interferograms in California with implications for future fault creep study. Chapter 6 proposes an optimal way to combine GPS and InSAR to measure interseismic deformation, including fault creep. The proposed method is compared with other method and the improvements are observed. Chapter 7 presents the conclusions of the previous six chapters. Chapter 8 presents my work in the first two years in graduate school, which is not related to fault creep. We compute global maps of surface minus basal heat flow that show qualitative agreement with heat flow based on the inverse square root of age relation. In the beginning of each chapter, I provide you an earthquake safety tip. I borrowed them from an interesting website for your safety and interests. Hopefully it could be one more motivation to read through my thesis. I didn't bother to invent them, as Ralph Waldo Emerson noted "All my best thoughts were stolen by the ancients."

Book Synopsis Seismic Velocity Contrasts and Temporal Changes of Strike-slip Faults in Central California by : Peng Zhao
Download or read book Seismic Velocity Contrasts and Temporal Changes of Strike-slip Faults in Central California written by Peng Zhao and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 zone head wave (FZHW) is used to image the bimaterial fault interfaces. The results show clear variations of seismic velocities contrast both along-strike and along-depth directions in both regions, which is in general consistent with local geological setting at surface and existing 3D tomography results. In the Parkfield section of SAF, the result of velocity contrast is used to test the relationship between preferred rupture directions of M6 Parkfield earthquakes and bimaterial interface. Strong velocity contrast (~5-10%) near Middle Mountain (MM) could control the rupture directions of nearby earthquakes to SE, such as the case for 1966 M6 Parkfield earthquake. In comparison, weak velocity contrast (~0-2%) near the epicenter of the 2004 Parkfield M6 earthquake (i.e., Gold Hill) probably has no influence on controlling its rupture direction, which is consistent with the bilateral rupture of the 2004 Parkfield earthquake. In the central Calaveras Fault, a detailed analysis of the moveout between FZHWs and direct P waves revealed the existence of a complicated fault structure with velocity contrast increasing from NW to SE of station CCO. The high velocity contrast SE of station CCO could be caused by a low-velocity zone SE of station CCO. : The spatio-temporal variations of seismic velocity around the central Calaveras Fault and its nearby region are investigated based on the waveform analysis of 333 repeating clusters following the 1984 ML6.2 Morgan Hill earthquake. Clear reduction of seismic velocity is shown for all repeating clusters immediately after the mainshock, followed by a logarithmic recovery. The coseismic change mostly occurs at shallow layers (top few hundred meters) for the region away from the rupture area of the mainshock, but extends much deeper around the rupture zone of the Morgan Hill earthquake. The estimated depth of the damage zone is up to 6 km in the fault based on the repeating clusters directly beneath station CCO.
