in this research, a new mathematical modeling on strength changes due to reservoir elastic stresses across the preexisting fault plane is introduced. the method has been applied to the dalpari fault, which is one of the potential seismic sources in the vicinity of the karkheh reservoir. in this method the distribution of total stress across the fault cannot be determined because the initial str...

ardekoul fault zone which is along nnw-sse is located in eastern iran and northern part of the sistan subzone. dextral strike-slip fault zone of ardekuol is made of six main segments including korizan (28 km), bohn abad (8.8 km), abiz (32 km), gazkoon (20 km), moein abad (30.4 km), ghal maran (12 km), and two minor segments including olang morgh (12.8 km) and seh pestan (9.6 km).  the studied r...

Abstract This paper presents wavelet based analysis for transmission line fault location. Faults in power transmission lines cause transients that travel at a speed close to the speed of light and propagate along the line as traveling waves (TWs). Traveling wave theory is utilized in capturing the travel time of the transients along the monitored lines between the fault point and the protective...

During large earthquakes, seismic sources tend to split in several sub-events that rupture neighboring fault patches called segments. The scaling of such segmentation plays a decisive role earthquake dynamics, especially for strike-slip events. Using numerical modeling we demonstrate when pristine layer brittle material is sheared, the first oblique Riedel fractures nucleate with regular spacin...

It is believed that Greater India migrated from the southern hemisphere, collided with Gondwanaland, Angaraland and Cathaysia, thereby closing an intervening oceanic Tethys along the Indus-Yarlung-Tsangpo Suture Zone (IYTSZ).The suture zone is placed along the Chaman Fault in the Baluchistan-Afghanistan area in the west, and the Indus-Yarlung-Tsangpo in the north, whereas along the east from Th...

The presence of radon in drinking water causes health risks associated with exposure from both inhalation and ingestion. Since the studies show that faults near the water resources have a critical effect on the concentration of radon, Kouhbanan active fault zone, to find water resources  with high radon concentration was chosen for the following investigation. Water samples were taken from all ...

Unraveling complex slip histories in fault damage zones to understand relations among deformation, hydrothermal alteration, and surface uplift remains a challenge. The dextral eastern Denali zone (EDFZ; southwest Yukon, Canada) bounds the Kluane Ranges hosts variety of fault-related rocks, including hematite surfaces, which have been exhumed through brittle regime over protracted period geologi...
