Site Characterization Using Integrated Imaging Analysis Methods on Satellite Data of the Islamabad, Pakistan, Region [PDF]

open access: yes, 2008
We develop an integrated digital imaging analysis approach to produce a first-approximation site characterization map for Islamabad, Pakistan, based on remote-sensing data. We apply both pixel-based and object-oriented digital imaging analysis methods to

Investigating Near Surface S-Wave Velocity Properties Using Ambient Noise in Southwestern Taiwan

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2015
Ambient noise is typically used to estimate seismic site effects and velocity profiles instead of earthquake recordings, especially in areas with limited seismic data.

Geotechnical Characterization of TriNet Sites: A Status Report [PDF]

open access: yes, 2004
The TriNet project, launched in 1997, created an improved, real-time seismic monitoring network in Southern California. Planning of the network began in 1995 (e.g., Heaton et al., 1996), building on the success of the earlier TERRAscope network, which

Comparisons among the five ground-motion models developed using RESORCE for the prediction of response spectral accelerations due to earthquakes in Europe and the Middle East [PDF]

open access: yes, 2013
This article presents comparisons among the five ground-motion models described in other articles within this special issue, in terms of data selection criteria, characteristics of the models and predicted peak ground and response spectral accelerations.

局部场地地震动高频衰减系数估计模型

open access: yesDizhen xuebao, 2023
采用随机有限断层法进行地震动模拟时,选用合理的参数描述特定局部场地近地表高频衰减特征,对评价地震动模拟结果的正确与否具有重要的实践意义。 在工程场址地震动参数预测中,如何快速确定参数的取值,是实际应用中亟需解决的问题。首先对场地高频衰减系数κ0与平均剪切波速vS30的相关性进行了分析;然后,基于国内外学者计算得到的546个κ0系数,采用一定时窗内的κ0均方根值,讨论其随平均剪切波速vS30增加的变化趋势。 结果表明,虽然κ0具有明显的区域差异性,但其均方根值随着vS30的增大呈现出逐渐减小的趋势 ...

VS30, slope, H800 and f0 [PDF]

open access: yes, 2020
The aim of this paper is to investigate the ability of various site-condition proxies (SCPs) to reduce ground-motion aleatory variability and evaluate how SCPs capture nonlinearity site effects. The SCPs used here are time-averaged shear-wave velocity in the top 30 m (VS30), the topographical slope (slope), the fundamental resonance frequency (f0) and ...

Understanding the physics of kappa (κ): Insights from a downhole array [PDF]

open access: yes, 2015
At high frequencies, the acceleration spectral amplitude decreases rapidly; this has been modelled with the spectral decay factor κ. Its site component, κ0, is used widely today in ground motion prediction and simulation, and numerous approaches have ...
