An earthquake of M, = 5.3 occurred at 32°58.7'N, 117°51.5'W southwest of Oceanside in San Diego County at 13:47 13 July 1986 (UT). This main shock was followed by an extensive aftershock sequence, with 55 events of ML > 3.0 during July 1986. The epicenters of the main shock and aftershocks are located at the northern end of the San Diego Trough-Bahia Soledad fault zone (SDT-BS) where it changes...

Given shale's potential to serve as both a caprock for geological carbon sequestration and the host nuclear waste disposal, this study focuses on structural characterization around 1.5–3 m thick fault within Opalinus Clay rock petrophysical of core. Seven boreholes were drilled at Mont Terri Rock laboratory in late 2018 constrain orientation so-called ‘Main Fault’ several fracture families core...

We present a new, high spatial resolution image of stress orientation in southern California based on the inversion of earthquake focal mechanisms. We use this image to study the mechanics of faulting in the plate boundary region. The stress field contains significant spatial heterogeneity, which in some cases appears to be a result of the complexity of faulting and in other cases appears to be...

Localized fragmentation is an important phenomenon associated with the formation of shear bands and faults in granular media. It can be studied by empirical observation, by laboratory experiment, or by numerical simulation. Here we investigate the spatial structure and statistics of fragmentation using discrete element simulations of the strain-controlled uniaxial compression of cylindrical sam...

Estimating the expected size of the largest earthquake on a given fault is complicated by dynamic rupture interactions in addition to geometric and stress heterogeneity. However, a statistical assessment of the potential of seismic events to grow to larger sizes may be possible based on variations in magnitude distributions. Such variations can be described by the b-value, which quantifies the ...

The steady reduction of transistor size has brought embedded solutions into everyday life. However, the same features of deep-submicron technologies that are increasing the application spectrum of these solutions are also negatively affecting their dependability. Current practices for the design and deployment of hardware fault tolerance and security strategies remain in practice specific (defi...

Films of (10 10) textured CoCrPt have been sputtered on polymer substrates for use as thin film tape media. Underlayers of NiAl combined with various intermediate layers were employed to obtain this orientation without thermal damage to the polymer. It was found that NiAl underlayers sputtered on tape substrates have a (112) growth texture, like they do on glass. Film coercivity varied as a fun...

The NNW-trending Dena Fault, with 140 km length, cuts the major structures of Zagros Fold-Thrust Belt in Borujen region. The fault has divided the region in two zones, in which different structural, andmorphological features as well assedimentation and seismtectonic characteristics have developed. This study presents a new interpretation for the kinematics of Dena Fault based on field evidence....
