We estimate the critical slip-weakening distance on earthquake faults by using a new approach, which is independent of the estimate of fracture energy or radiated seismic energy. The approach is to find a physically based relation between the breakdown time of shear stress Tb, the time of peak slip-velocity Tpv, and the slip-weakening distance Dc, from the time histories of shear stress, slip, ...

We study how the fault dip and slip rake angles affect near-source ground velocities and displacements as faulting transitions from strike-slip motion on a vertical fault to thrust motion on a shallow-dipping fault. Ground motions are computed for five fault geometries with different combinations of fault dip and rake angles and common values for the fault area and the average slip. The nature ...

Abstract We present a series of analogue models inspired by the geology Zürcher Weinland region in Northern Alpine Foreland Basin Switzerland to explore influence rheological weak, i.e. (partially) ductile layers on 3D evolution tectonic deformation. Our model test impact varying weak layer thickness and rheology, as well different kinematics an underlying “basal fault”. Model analysis focuses ...

BERRY, R.F. & BANKS, M.R., 1985 (31 :vii): Striations on minor faults and the structure of the Parmeener Super-group near Hobart, Tasmania. Pap. Proc. R. Soc. Tasm. 119:23-29. ISSN 0080-4071. University of Tasmania, Hobart, Tasmania, Australia, 7000. Fault striations were measured on 104 minor faults within the Parmeener Super-group near Hobart. The fault striations probably reflect the complex...

Geodesy shows that ?7 mm/yr of dextral shear is accumulating across the Central Walker Lane in absence through-going strike-slip faults. To better understand how this accommodated, we describe and quantify patterns slip rates active faults extending between Lake Tahoe basins. Lidar data geomorphic mapping show linear fault traces stepping geometries consistent with accommodation oblique-slip mo...

the zagros fold- thrust belt as a part of alpine- himalayan orogenic belt, is one of the most active continental collision zones on the earth, which extends from the tarus mountains in south eastern turkey to the minab fault in the east of the strait of hormoz in southern iran. structurally, its formation is related to the continuing convergent movement between the arabian plate to the southwes...

[1] The tectonic evolution of Mars has been driven primarily by the interaction of Tharsisinduced loading stresses with a uniform contractional stress field, leading to global assemblages of graben and wrinkle ridges. Until recently, strike-slip faults have appeared to be largely absent from the tectonic record. We here present evidence for a new set of Noachian to Early Hesperian strike-slip f...

We use three-dimensional dynamic (spontaneous) rupture models to investigate the nearly simultaneous ruptures of the Susitna Glacier thrust fault and the Denali strike-slip fault. With the 1957 Mw 8.3 Gobi-Altay, Mongolia, earthquake as the only other well-documented case of significant, nearly simultaneous rupture of both thrust and strike-slip faults, this feature of the 2002 Denali fault ear...
