Fault step-overs with linking dip-slip faults are common features on long strike-slip fault systems worldwide. It has been noted by various researchers that under some circumstances, earthquakes can jump across fault step-overs to cascade into large events, while under other circumstances rupture is arrested at stepovers. There is also evidence that fault step-overs may be preferential location...

Model-driven architecture (MDA) based paradigms generate a complete specification of the target system in addition to its implementation. Such a specification facilitates the formal analysis and prediction of the characteristics of the target system. The prerequisite of the analysis of nonfunctional properties is the extension of the model by the corresponding component and interaction characte...

Smart fault current controller (SFCC) proposed in our previous work consists of a power converter, a high temperature superconducting (HTS) DC reactor, thyristors, and a control unit [1]. SFCC can limit and control the current by adjusting firing angles of thyristors when a fault occurs. SFCC has complex structure because the HTS DC reactor generates the loss under AC. To use the DC reactor und...

We present a method of constructing low-dimensional nonlinear models describing the main dynamical features of a discrete 2-D cellular fault zone, with many degrees of freedom, embedded in a 3-D elastic solid. A given fault system is characterized by a set of parameters that describe the dynamics, rheology, property disorder, and fault geometry. Depending on the location in the system parameter...

Several recent earthquake events (e.g., 2008 moment-magnitude (MW) 8.0 Wenchuan, China; 2016 MW 7.8 Kaikōura earthquake, New Zealand; 2019 6.4–7.1 Ridgecrest sequence, USA) have emphasized the need to explicitly account for fault sources in probabilistic seismic hazard analysis (PSHA). Fault-based PSHA currently involves a number of significant but necessary modeling assumptions that mainly rel...

The consequences to structures caused by permanent fault displacement have been investigated for dip-slip faulting, but not the effect of embedment depth on interaction between a normal rupture and shallow embedded foundation. This study foundation using numerical model validated with centrifuge experiments. It was found that gapping mechanism distress occurred at different positions relative o...
