Effects of Off‐Fault Inelasticity on Near‐Fault Directivity Pulses
Journal of Geophysical Research: Solid Earth, 2019 AbstractNear‐fault motion is often dominated by long‐period, pulse‐like particle velocities with fault‐normal polarization that, when enhanced by directivity, may strongly excite middle‐ to high‐rise structures. We assess the extent to which plastic yielding may affect amplitude, frequency content, and distance scaling of near‐fault directivity pulses.

Near‐fault anisotropy following the Hector Mine earthquake [PDF]
Journal of Geophysical Research: Solid Earth, 2003 We present anisotropy measurements from shear wave splitting along the Hector Mine rupture zone. Six major arrays were deployed in four locations in the year following the M7.1 Hector Mine earthquake. The dense station coverage, wide distribution of the arrays, and repeated deployments show a clear predominant fast direction and spatial variation of ...

Applied Sciences, 2020 The velocity pulse contained in near-fault ground motions have a tremendous impact on dam safety. Previous studies have mainly focused on the response of dams under near-fault seismic records without considering the obliquely incident seismic waves.

Shock and Vibration, 2021 Investigations into the Wenchuan earthquake (2008, China) demonstrated that landslides were concentrated in the near-fault areas, and numerous large-scale landslides occurred in slopes with weak interlayers.

Deep test hole drilled near fault
Eos, Transactions American Geophysical Union, 1980 In an effort to answer troublesome questions about stresses on the San Andreas fault, a team of U.S. Geological Survey (USGS) researchers is compiling data from in situ measurements in the deepest hole ever drilled, for scientific purposes, on or near the San Andreas fault.Headed by Mark Zoback, the team recently finished drilling the 1‐km hole, made ...

Terrestrial, Atmospheric and Oceanic Sciences, 2016 Near-fault ground motion is a key to understanding the seismic hazard along a fault and is challenged by the ground motion prediction equation approach. This paper presents a developed stochastic-slip-scaling source model, a spatial stochastic model with

Nonlinear Seismic Responses of Near-Fault Building Clusters Caused by the Fault Rupture
BuildingsAn integrated numerical method is proposed for analyzing the nonlinear seismic response of near-fault building clusters, comprising three algorithms: (1) a structural investigated lump algorithm for elastoplastic dynamic response of structure; (2) a ...
