Understanding the role of southeastern Tibetan thrust faults in development plateau topography is key to our assessment geodynamic processes shaping continental topography. Detailed structural analysis along ~400 km long Jinhe-Qinghe belt (JQTB) indicates post Late Eocene motion with a minor left-lateral component, inducing ~0.6 3.6 apparent vertical offset across fault. The exhumation history ...

This paper aims to present a new neotectonic perspective concordant with the seismic activities in Turkey and surrounding regions. The structures have been re-evaluated mainly by using focal mechanism solutions high-resolution satellite (Google Earth) images. Southeast Anatolian Wedge explains thrust/blind thrust asymmetrical folding relationship SE Turkey, Syria, Northern Iraq. of Turkish-Iran...

Abstract The southwest Iberia margin is widely believed to have hosted the 1755 Great Lisbon earthquake and ensuing tsunami, one of most destructive natural events in European history. Here we combine geophysical data numerical tsunami modelling investigate source mechanism responsible for this event. We find that an intra-plate, lithospheric¬-scale thrust fault located at Horseshoe Abyssal Pla...

Balanced cross-sections across the Zagros fold–thrust belt in Iran are used to analyze the geometry of deformation within the sedimentary cover rocks, and to test the hypothesis of basement involved thrusting throughout the fold–thrust belt. Although the Zagros deformation front is a relatively rectilinear feature, the sinuous map-view morphology of the mountain front is a result of a 6 km stru...

[1] We report on laboratory experiments examining the frictional and hydrologic properties of fault gouge and wall rock along a borehole transect that crosses a major out-of-sequence thrust splay fault within the Nankai accretionary complex. At 25 MPa effective normal stress, the fault zone material is frictionally weak (m 0.44) and exhibits low permeability after shearing (k < 5.5 10 20 m). Fa...

Analogue experiments were carried out to get insights into the processes governing positive inversion during the foreland propagating thrust tectonics in the southern Serra do Espinhaço, a Brasiliano/Panafrican foldthrust belt in southeast Brazil. In particular, model listric half-grabens were inverted by applying contractional displacement to the footwall blocks. We investigated two different ...

In this study, we develop stochastic random-field slip models for the 2011 Tohoku earthquake and conduct a rigorous sensitivity analysis of tsunami hazards with respect to the uncertainty of earthquake slip and fault geometry. Synthetic earthquake slip distributions generated from the modified Mai-Beroza method captured key features of inversion-based source representations of the mega-thrust e...

The Khushab anticline is located in the Zagros fold-thrust belt in the Lurestan. This anticline is affected by the Balarud fault zone, which is a part of Mountain Front Fault between the Lurestan and Dezful Embayment zones. Based on the measurement of the elements of fold style, this anticline is analyzed. According to these measurements, this anticline is a noncylindrical, asymmetrical and dis...
