A finite element method with constrained elements and Lagrange multipliers is used to study tectonic faults in a viscous medium. A fault, representing the interface between overriding and subducting plates, has been incorporated into a viscous flow model of a subduction zone in which both thermal buoyancy and the buoyancy associated with the phase change from olivine to spinel are included. The...

This study intends to evaluate the possible correlation between dimension (DC) and seismic moment rate for different late Quaternary active fault data, shallow crustal earthquakes, GPS on island of Sumatra Probabilistic Seismic Hazard Analysis (PSHA). The seismicity smoothing was applied estimate DC faults (DF) earthquake data (DE) then correlate that with b-value, which will be used identify h...

In this paper, a new fast and accurate method for fault detection, location, and classification on multi-terminal DC (MTDC) distribution networks connected to renewable energy and energy storages presented. MTDC networks develop due to some issues such as DC resources and loads expanding, and try to the power quality increasing. It is important to recognize the fault type and location in order ...

[1] We studied the anatomy of the fault system where the 2009L’Aquila earthquake (MW 6.1) nucleated by means of ~64 k high-precision earthquake locations spanning 1 year. Data were analyzed by combining an automatic picking procedure for P and S waves, together with cross-correlation and double-difference location methods reaching a completeness magnitude for the catalogue equal to 0.7 includin...

A fault simulator for large synchronous sequential circuits is presented in this paper. There are four key ideas to the fault simulator. 1) It uses the critical path tracing method to screen out the single event faults that need not map into equivalent stem faults. 2) It uses the single fault propagation method to map the traced single event faults into equivalent stem faults. 3) All the multip...

It is well known that series arc faults in Low Voltage DC (LVDC) distribution system occur at unintended points of discontinuity within an electrical circuit. These faults can make circuit breakers not respond timely due to low fault current. It, therefore, is needed to detect the series fault for protecting circuits from electrical fires. This paper proposes a novel scheme to detect the series...

Shear failure is the dominant mode of earthquake-causing rock failure along faults. High fluid pressure can also potentially induce rock failure by opening cavities and cracks, but an active example of this process has not been directly observed in a fault zone. Using borehole array data collected along the low-stress Chelungpu fault zone, Taiwan, we observed several small seismic events (I-typ...
