ESG1992 Symposium on the Effects of Surface Geology on Seismic Motion

这个研讨会是一项正在进行的全球努力的一部分，目的是更好地了解地表地质对地震破裂传播的波的影响。具体来说，这是通过包括两个阶段的实验来完成的：通过“盲目”预测和分析（即在进行实验之前进行预测）收集弱运动和强运动数据并进行模型测试。美国和日本已经分别进行了试验；在土耳其平原，CA和Ashigara山谷，神奈川，日本。ESG1992研讨会的目标是汇集来自世界各地的研究人员，他们利用土耳其平原和Ashigara山谷的数据进行了盲目预测，为了将个人和总结结果和分析呈现给：1)深入了解近地表地质对地震运动特性的影响；2)评估模型和建模方法；3)确定未来的研究方向。这是计划举行的两次现场反应专题讨论会中的第一次。第二次将在美国举行，因为预计帕克菲尔德将发生强震，CA（美国地质调查局的官方预测）。这一行动是为参加本次研讨会的四位美国研究人员提供旅费支持。

This workshop is part of an ongoing and worldwide effort to better understand the effects of surface geology on the waves propagating from an earthquake rupture. Specifically, this is being done through experiments which consist of two phases: weak motion and strong motion data collection and model testing through "blind" prediction and analysis (that is, the predictions are made in advance of the experiment being performed). The United States and Japan have separately implemented experiments; at Turkey Flat, CA and in the Ashigara Valley, Kanagawa, Japan. The objective of the ESG1992 Symposium is to bring together researchers from around the world who have made blind predictions using the Turkey Flat and Ashigara Valley data, in order to present individual and summary results and analyses to: 1) develop insights with respect to the effects of near-surface geology on properties of earthquake motions, 2) to evaluate models and modeling approaches and 3) to identify future directions for research. This is the first of two symposia on site response that are planned. The second will be held in the United States following the anticipated strong motion earthquake at Parkfield, CA (an official prediction made by the U.S. Geological Survey). This action is to provide travel support for four U.S. researchers to attend this symposium.
