Slip-Length Scaling in Large Earthquakes: The Role of Deep-Penetrating Slip below the Seismogenic Layer
Coseismic slip is observed to increase with earthquake rupture length for lengths far beyond the length scale set by the seismogenic layer. The observation, when interpreted within the realm of static dislocation theory and the imposed limit that slip be confined to the seismogenic layer, implies that earthquake stress drop increases as a function of rupture length for large earthquakes and, he...
متن کاملThe evolving interaction of low-frequency earthquakes during transient slip
Observed along the roots of seismogenic faults where the locked interface transitions to a stably sliding one, low-frequency earthquakes (LFEs) primarily occur as event bursts during slow slip. Using an event catalog from Guerrero, Mexico, we employ a statistical analysis to consider the sequence of LFEs at a single asperity as a point process, and deduce the level of time clustering from the s...
متن کاملComplementary slip distributions of the largest earthquakes in the 2012 Brawley swarm, Imperial Valley, California
[1] We investigate the finite rupture processes of twoM> 5 earthquakes in the 2012 Brawley swarm by joint inversion of nearby strong motion and high-rate GPS data. Waveform inversions up to 3 Hz were made possible by using a small event (Mw3.9) for path calibration of the velocity structure. Our results indicate that the first (Mw5.3) event ruptured a strong, concentrated asperity with offsets ...
متن کاملHolocene slip rates along the Owens Valley fault, California: Implications for the recent evolution of the Eastern California Shear Zone
One of the largest historical earthquakes in California occurred in 1872 along the Owens Valley fault located along the western margin of the Eastern California Shear Zone. New paleoseismic and optically stimulated luminescence data are the first to bracket the timing of the pre-1872 rupture to between 3.3 6 0.3 and 3.8 6 0.3 ka. These data yield an earthquake recurrence interval between 4100 a...
متن کاملTHE PENNSYLVANIA STATE UNIVERISTY DEPARTMENT OF GEOSCIENCES Estimating the Pleistocene Slip Rate of the Owens Valley Fault, California
Slip rates of the right-lateral Owens Valley Fault lie at the center of an ongoing debate over the rheology and mechanics of lithospheric deformation in eastern California. Slip rates determined from paleoseismic records of surface rupture yield Late Pleistocene – Holocene rates of < 1mm/yr to ~2 mm/yr. The decadal velocity field across the valley, however, approaches ~6 mm/yr of right-lateral ...
