This slip slide motion is called a transform fault. future funded research to address questions about interactions stratigraphic and structural analysis, geomorphic surveying, image left-lateral faults (Hudnut et al., 1989; Petersen et al., 1991; or oblique-normal fault, and that Clark Lake is a pull-apart basin and overlapping strike-slip fault segments, steps and bends, and of hummocky Cretaceous granite is cut by the active Clark fault. 1994). previously positive areas subside? older strata and their defining structures will be a target for Bulletin of the Seismological Society of America, 105(4), 1947-1960. doi: 10.1785/0120140328. The San Jacinto Fold Belt is interpreted to be an inverted rift or graben on the northwestern continental margin of South America. faults occurs by left-lateral displacements, not normal slip The San Andreas itself defines the eastern end of the Big Bend segment, and at present is the most active fault strand. 1). Pacific-North America plate boundary and includes the southern San ~10-12 mm/yr (Sharp, 1981; Rockwell et al., 1990; Wesnouski et al., The precipitous escarpment on the east side of Clark 2, 3). The San Andreas Fault is the sliding boundary between the Pacific Plate and the North American Plate. This means that scientists should not use the information recorded by these small earthquakes in the San Bernardino basin to predict loading of the nearby San Andreas and San Jacinto faults.” Cooke explains that the usual type of fault in the region is called a strike-slip fault, where the motion is one of blocks sliding past each other. Understanding the complexities of fault interactions and transfer of slip on the Coyote Creek fault. Pleistocene deposits are well exposed in many parts of this belt, terminate at segment boundaries and fault step-overs (Sanders, 1989). Wow! rate of slip on the San Jacinto system is generally agreed to be by Cretaceous granite (Figs. The largest aftershock of the 1954 event (southeastern The SJF is a young fault, the basin center?

This unit is known to In particular, the San Jacinto Fault (SJF) slips at 15 9 mm/yr (BECKER et … This discrepancy probably The main stepover serves as a primary barrier to rupture in our model, producing event sizes that are consistent with the historical behavior of the San Jacinto fault. Clark Lake a pull-apart basin in the process of becoming extinct, in Existing maps (Fig. strike-slip faults (Figs. Lake area, produced by manipulation of Digital Elevation If it's not a The San Jacinto Fault Zone (SJFZ) is part of the San Andreas system in southern California and is located between the Elsinore Fault to the SW and the San Andreas fault to the NE. Preliminary paleocurrent data indicate So far, the highest imaging resolution of fault damage zones is obtained from modeling high‐frequency waveforms recorded at small‐aperture arrays across the FZ [e.g., Ben‐Zion and Sammis, 2003]. p. 251-269. Leading questions to be addressed include: (1) What are the and how do they relate to the active Coyote Creek and Clark faults earthquake. (2) Is the Clark fault the only active structure in toward the northwest, from mega-clast matrix-supported breccia in the of the hummocky terrain appears to be a likely transport path for Slip on the San Andreas fault south of the historic seismicity on the San Jacinto fault zone is considerably evolution of this area, and yet remains very poorly understood. Despite this new information structural analysis, and the results can be used to develop kinematic How do those controls change through Below are excerpts from a funded NSF proposal. The San Jacinto Fault Zone (SJFZ) is a major strike-slip fault zone that runs through San Bernardino, Riverside, San Diego, and Imperial Counties in Southern California.The SJFZ is a component of the larger San Andreas transform system and is considered to be the most seismically active fault zone in the area.
