Analysis of deformational histories along polyphase reactivated faults commonly is based on the dating of cross-cutting relationships using relative ages of offset strata or geochronological ages of syntectonically grown minerals within fault planes. However, ten Veen and Postma (1999) and ten Veen and Kleinspehn (2000) introduced a new approach to reconstructing the vertical component of synse...

We reveal the source rupture process using the strong-motion data by the inversion analysis. The derived slip distribution shows one prominently large slip area extending from the hypocentre area to the shallow part of the fault along the trench axis, which is located far off the coastal region extensively damaged by the tsunamis. The shallow main rupture started 60 seconds after the initial br...

Abstract Two‐decades of onshore‐offshore, ocean‐bottom seismometer, and passive‐source data are integrated to obtain high‐resolution 3‐D constraints on the architecture Nankai subduction zone. Our model reveals large along‐strike variability in width outer‐forearc, with crustal backstop ( V P ≥ 5 km/s) extending within 50 km Trough offshore Tokai Kii Peninsula, but is a factor 2 further landwar...

The earthquake nucleation process has been vigorously investigated based on geophysical observations, laboratory experiments, and theoretical studies; however, a general consensus has yet to be achieved. Here, we studied nucleation process for the 2014 Iquique, Chile Mw 8.2 megathrust earthquake located within the current North Chile seismic gap, by analyzing a long-term earthquake catalog cons...

The compressive creep deforrn;~tiort microstructure of polycrystalline Ni3AI h:is been observed by transnlission electron microscopy (TEM). ( 1 1 I ) rind ( 110) slip systems have been identified in primary creep. Dissociatiort of edge superparti:~l pairs perpendicular to the slip plane (both { 11 1 ) and ( 110) ) is common in crept specimens. I'he formation of this superdislocation...

In the present study, crystal plasticity models applicable for reproducing work-hardening behavior under various loading paths of an A5083-O Al alloy sheet were examined. The consideration tension, reverse from compression to simple shear, and biaxial tension. accumulated-slip-based hardening model with extended Voce law provided good predictive accuracy uniaxial loadings. contrast, it could no...

[1] Residual mantle exposures in the accreted Talkeetna arc, Alaska, provide the first rock analog for the arc-parallel flow that is inferred from seismic anisotropy at several modern arcs. The peridotites exposed at the base of the Jurassic Talkeetna arc have a Moho-parallel foliation and indicate dislocation creep of olivine at temperatures of 1000 to >1100 C. Slip occurred chiefly on the (00...

Plasticity in magnesium crystals oriented for c-axis compression has been usually attributed to 〈cþa〉 dislocation slip on second-order pyramidal {112̄2} planes. Through molecular dynamics simulations, we investigated the formation and slip characteristics of 〈cþa〉 dislocations on second-order pyramidal planes. It is shown that the critical c-axis compressive stress for these dislocations is almo...

A unique method for quantitative in situ nanotensile testing in a transmission electron microscope employing focused ion beam fabricated specimens was developed. Experiments were performed on copper samples with minimum dimensions in the 100-200 nm regime oriented for either single slip or multiple slip, respectively. We observe that both frequently discussed mechanisms, truncation of spiral di...
