Following the devastating 2008 Wenchuan earthquake that ruptured the central–northern segments of the Longmenshan fault in Sichuan, China, many studies assessed its impact on other major faults in this region (e.g., Parsons et al., 2008; Toda et al., 2008). On 20 April 2013, theMw 6.6 Lushan earthquake ruptured the southern segment of the Longmenshan fault, allowing these assessments to be test...

[1] The San Andreas Fault (SAF) is the transform boundary between the Pacific and the North American plates, yet up to 25% of the relative plate motion is now accommodated by the eastern California shear zone (ECSZ). Here we investigate the inception of the ECSZ and its geodynamic interactions with the SAF using a 3‐D viscoelastoplastic finite element model. For a given fault configuration of t...

-In radial distribution network with no discontinuities in feeders’ impedances the shape of traveling wave induced by an SLG fault inception will be modeled by multiple refractions and reflections from busbar, fault and loads. The initial propagation zone presents a rigorous polarity disposition of residual currents, with sound residuals having the same polarity. We can determine the minimal sa...

The Coyote Creek fault is a major strand of the San Jacinto fault zone in southern California. Pleistocene sediments and sedimentary rocks exposed in the lower Coyote Creek area preserve a record of surface deformation, stream reorganization, and erosion that resulted from initiation and slip on the Coyote Badlands strand of the Coyote Creek fault. A well-exposed section of conglomerate and san...

due to their inherent sensitivity to resistivity contrast, em methods have an important role in detection of fault zones. in this paper, we experienced controlled source tensor magnetotelluric (cstmt) method to recognize a fault zone in bam area. an earthquake devastated the town of bam on 26 december 2003. surface displacements reveal that over 2 m of slip occurred at depth on a fault that had...

[1] By measuring relative earthquake arrival times using waveform cross correlation and locating earthquakes using the double difference technique, we are able to reduce hypocentral errors by 1 to 2 orders of magnitude over routine locations for nearly 8000 events along a 35-km section of the Calaveras Fault. This represents 92% of all seismicity since 1984 and includes the rupture zone of the ...

deformation pattern of the northeastern part of the iranian-arabian collision zone (i.e., mainly sanandaj-sirjan belt or zone) is the main concern of this paper. here, we investigate the stress distribution and displacement pattern of eghlid-deh bid area as affected by the position of zagros suture using a three dimensional mechanical model. the modeled area is located between the zagros thrust...

The injected CO2 in a target formation can continue to migrate through permeable pathways due to geological heterogeneity as well as buoyancy. This movement drives a countercurrent flow of brine leading to increased residual phase trapping. The purpose of this simulation study is to understand the effects of geological structures, especially faults, on the dynamic behavior of the buoyancy-drive...

[1] The relationship between small-magnitude seismicity and large-scale crustal faulting along the Hayward Fault, California, is investigated using a double-difference (DD) earthquake location algorithm. We used the DD method to determine high-resolution hypocenter locations of the seismicity that occurred between 1967 and 1998. The DD technique incorporates catalog travel time data and relativ...
