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...

In this study, Interferometric Synthetic Aperture Radar (InSAR) was used to determine the seismogenic fault and slip distribution of the 3 July 2015 Pishan earthquake in the Tarim Basin, western China. We obtained a coseismic deformation map from the ascending and descending Sentinel-1A satellite Terrain Observation with Progressive Scans (TOPS) mode and the ascending Advanced Land Observation ...

The characteristics of active fault movements are essential for estimating the earthquake potential on Tibetan Plateau (TP) in a complex geological setting. 2022 Menyuan Mw6.7 was studied by joint seismological and geodetic methodology to deepen scientific understanding source parameters deformation mechanisms. Firstly, entire InSAR co-seismic field is obtained based ascending descending Sentin...

In this work, we prove the usefulness of morphometric analyses, typically applied to basin-border faults, define tectonic geomorphology a slow-moving, intrabasinal structure: Galera Fault (Guadix-Baza Basin, southern Spain). The is 30 km-long, oblique-slip fault with major left-lateral and minor vertical slip components. Through geological structural for first time detailed surface geometry fau...

S U M M A R Y The Mw 7.6 1997 Manyi earthquake occurred in an area of central northern Tibet where sparse vegetation coverage and a lack of human habitation provide excellent conditions for Interferometric Synthetic Aperture Radar (InSAR) studies. We use coseismic pairs of radar images acquired by the ESA ERS-2 satellite to construct interferograms of the surface displacement field due to the e...

InSAR images allow to detect the coseismic deformation, delimiting epicentral area where larger displacement has been concentrated. By inspecting fringe patterns it is commonly recognized that, for dip-slip faults, most deformed elliptical, or quadrilobated strike-slip faults. This coincides with surface projection of volume coseismically mobilized in hanging wall thrusts and normal crustal wal...

Sigmoidal fold and fault geometries are typical kinematic indicators of strike-slip zones. We document kilometer-scale, normal faults with sigmoidal plan-view within the dextral pull-apart Bahia Basin, at rear obliquely convergent South Caribbean Deformed Belt, offshore Colombia. Using 3D seismic reflection data calibrated to wells, closely spaced, low-displacement, planar mapped Miocene strata...

[1] Paleoseismic exposures excavated across relatively straight sections of major faults in southern California display a high degree of localization at depths of only a few meters below the surface. In some cases, the width of the slip zone in events with multimeter displacement is on the order of 1–2 mm to a cm, which is the resolution of the observations. Repetitive slip events in the same z...
