During the great 3 May 1887 Sonoran earthquake (surface rupture end-to-end length: 101.8 km; MW = 7.5±0.3), an array of three north-south striking Basin and Range Province faults (from north to south Pitáycachi, Teras, and Otates) snapped along the western margin of the Sierra Madre Occidental plateau. My detailed fi eld survey of the Teras fault and the 1887 earthquake rupture zone along this ...

The northeastern margin is a natural experimental field for studying crustal extrusion and expansion mechanisms. accurate deformation pattern key point in the analysis of regional mechanisms seismic hazard research judgment. In this paper, present-day GPS velocity on Tibetan Plateau was obtained from encrypted observations around Haiyuan–Liupanshan fault zone, combined with 2010 to 2020. Firstl...

Numerous methods have been proposed to automatically extract fault surfaces from 3D seismic images, and those surfaces are often represented by meshes of triangles or quadrilaterals. However, extraction of intersecting faults is still a difficult problem that is not well addressed. Moreover, mesh data structures are more complex than the arrays used to represent seismic images, and they are mor...

Deformation and focused fluid flow within a mineralized system are critical in the genesis of hydrothermal ore deposits. Dilation and integrated fluid flux due to coupled deformation and fluid flow in simple strike–slip fault geometries were examined using finite difference analysis in three dimensions. A series of generic fault bend and fault jog geometries consistent with those seen in the we...

The ability of the human immunodeficiency virus, type 1 (HIV-1) protein Nef to induce cytoskeleton changes in infected host cells is a key event in viral replication. In renal podocytes, we found that Nef induced loss of stress fibers and increased lamellipodia, pathological changes leading to proteinuria in HIV-associated nephropathy. These morphological changes were mediated by Nef-induced Ra...

[1] Radially fractured centers (RFCs) on Venus are distinctive, 100 km long radiating systems of graben, fissures, and fractures arranged around a central topographic high. We use cycle 1 and cycle 3 Magellan images to determine the depths and wall dip angles of several large radial graben, using two different methods, at four RFCs: Becuma Mons, Didilia Corona, H’uraru Corona, and Pavlova Coron...

Normal mode solutions for • spherical earth model are superposed to obtain realistic synthetic surface waves for various force systems. The calculation of excitation functions is greatly facilitated by the variational technique. The effects of attenuation anal instrument response are included in the synthesis. The synthesized seismograms are compared with the actual seismograms for wave form, a...

The workflow for the practical application of the automated focusing analysis in time domain is demonstrated by deriving the TTI anisotropy parameters, epsilon and delta, from the previous VTI work in a small portion of the MC Revival survey located in the Mississippi Canyon area. The improvements are achieved for focusing of the dip events, optimized fault plane position, and imaging for base ...

We use interferometric synthetic aperture radar (InSAR) observations to investigate the coseismic deformation and slip distribution of the 1997 Mw7.5 Manyi earthquake, a left-lateral strike-slip earthquake occurred on the west portion of the Kunlun fault in the northern Tibet, China. The fault trace is constrained by the combination of interferometric coherence image and azimuth offset image. T...
