[1] The >300-km long, east striking Lapeiquan fault lies in the eastern Altyn Tagh range along the northern margin of the Tibetan Plateau and was interpreted as a north dipping thrust in early studies. However, our mapping shows that the fault is a south dipping normal fault juxtaposing Archean-Proterozoic gneisses beneath an early Paleozoic volcanic and sedimentary sequence. Its dip angle vari...

Assessing fault activity in regions lacking Quaternary sedimentary constraints remains a global challenge. In this study, we used channel slope distribution to examine variations rock uplift along faults. By comparing steepness with published low-temperature thermochronology and paleo-seismic data, identified deformation changes both perpendicular the Longmen Shan at various time scales. Our da...

We here use a 3D seismic reflection dataset from the Outer Kwanza Basin, offshore Angola to examine structure and growth of salt-detached strike-slip faults. The faults occur in four, up 13.8 km-long, NE-trending arrays that are physically linked by restraining bends releasing stepovers, which presently overlie Aptian salt base-salt relief related pre-salt faulting. suggest these formed accommo...

The network of fault zones caused by vertical and horizontal tectonic displacements blocks Earth’s crust relative to each other is clearly visible on the surface in images obtained from satellite surveys. Many researchers distinguish linear annular structures among faults. Lineaments are detected as rectilinear objects with a certain spectral brightness. initial data for experimental research i...

Abstract Strain energy from tectonic loading can be partly released through aseismic creep. Earthquake repeaters, repeatedly activated brittle fault patches surrounded by creep, indicate steady‐state creep that affects the amount of seismic available for next large earthquake along a plate contact. The offshore Main Marmara Fault (MMF) North Anatolian Zone represents gap capable generating M &g...

Understanding carbon dioxide (CO2) reservoir to surface migration is crucial successful capture and sequestration approaches; especially fault/reservoir interactions under injection pressure. Through seismic imaging, we explore regolith shallow stratigraphy across the Little Grand Wash fault. The presence of natural CO2 seeps, travertine tufa deposits confirm modern ancient fault-controlled lea...

In the present study seismicity of Southern Marmara Region before and after 1999 İzmit earthquake are analyzed compared. A homogeneous catalogue that have completeness above MC=2.9 covers time period between 1978 2020 is used. Comparison spatial mapping frequency-magnitude distribution revealed b-values demonstrate a general increase indicating stress decrease in region. The shortest computed T...
