By using GPS-derived velocities of 2015–2021 and a negative dislocation program, we inverted the locking degree slip rate deficit in Qilian–Haiyuan fault zone, combined with distribution small earthquakes fault, studied characteristics before 2022 Menyuan M S 6.9 earthquake analyzed future seismic hazards each segment within this zone. The regional crustal deformation pattern is discussed regar...

the doruneh fault is one of the longest and most prominent faults in iran. however, only two recorded historical earthquakes with magnitudes more than 7 might be related to this fault. for getting more information on this fault more investigation in different fields are required. fault displacement is one of the most important parameters needed to explore the fault activity. in this study, with...

The 2021 Mw 7.3 Maduo earthquake revealed the significant seismic hazard of faults developed within Bayan Har Block eastern Tibet, China (e.g., Kunlun Pass–Jiangcuo Fault). Relocated aftershock data are in good agreement with Interferometric Synthetic Aperture Radar (InSAR) coseismic displacement field and investigations. In this study, we used point cloud fitting to model relocated aftershocks...

The characteristics of near-fault ground motion are investigated considering heterogeneous slip distribution on the fault plane. Areas on the fault plane with large slip in compare with the average slip on the fault are known as asperity. The characteristics of strong ground motions in near-fault area are strongly affected by faulting parameters such as asperity location, maximum slip of asperi...

The voltage and current measurement of the medium-voltage (MV) side are used for traditional fault location method, which leads to a high installation cost complicated post-operational maintenance work. A method is proposed based on distributed at low-voltage (LV) side. On analysis distribution rules influence transformer transmission, obvious differences found in variation (phase sequence volt...

[1] We studied the complex multiple-faulting pattern of the 40-km-long rupture zone of the 1999 M7.1 Hector Mine, California, earthquake with fault zone trapped waves generated by near-surface explosions and aftershocks, and recorded by linear seismic arrays deployed across the surface rupture. The explosion excited trapped waves, with relatively large amplitudes at 3–5 Hz and a long duration o...

Image segmentation has received extensive attention due to the use of high-level descriptions of image content. This paper proposes a fault diagnosis model using a Gabor filter on segmented two-dimensional (2D) gray-level images. The proposed approach first converts time domain AE signals into 2D gray-level images to exploit texture information from the converted images. 2D discrete wavelet tra...

the alborz mountains, as a folded and faulting region, is the northern region of crust shortening in iran. dominant mechanism (harvard, 2002) of alborz earthquakes is left-lateral strick-slip paralleled to the range. east alborz is one of the active regions that plays a significant role in the tectonics of its neighbors like south casbin basin. regarding the geological maps of the area, the fau...
