4th International IASPEI Symposium on Effects of Surface Geology on Seismic Motion UC Santa Barbara, 23 - 26 August, 2011

第四届IASPEI/IAEE地表地质对地震运动的影响(ESG)国际研讨会将于2011年8月23日至26日在加州大学圣巴巴拉分校举行。来自世界各地的约250名科学家和工程师预计将出席这次研讨会，介绍有关当地场地条件如何影响地震引起的地面运动的最新结果。自2006年格勒诺布尔第三次研讨会以来，日本、中国、意大利、海地、智利、墨西哥和新西兰都发生了重大地震，提供了丰富的数据。特别是，2010年新西兰达菲尔德事件和2011年日本东北事件引发了广泛的液化。对这些事件的数据进行分析，并将结果传播到更大的社区，将有助于减轻未来地震的破坏影响。这次会议将把国际地震科学家和工程师社区聚集在一起。它将促进跨学科的思想交流，并为每个人提供关于量化当地遗址地质学影响的基本问题的最新研究成果。在会议上提交的论文将以光盘形式出版，并分发给所有登记的与会者。这些论文还将通过会议网站向公众提供。

The 4th International IASPEI/IAEE Symposium on the Effects of Surface Geology on SeismicMotion (ESG) will be held at the University of California, Santa Barbara from 23 ? 26 August2011. Approximately 250 scientists and engineers from around the world are expected to attendthis symposium to present the latest results on how local site conditions affect ground motioninduced by earthquakes. Since the 3rd Symposium in Grenoble in 2006, there have beensignificant earthquakes in Japan, China, Italy, Haiti, Chile, Mexico, and New Zealand that haveprovided a wealth of data. In particular, the 2010 Darfield event in New Zealand and the 2011Tohoku event in Japan induced widespread liquefaction. Analysis of the data from these eventsand dissemination of the results to larger communities will aid in the mitigation of damagingeffects from earthquakes in the future.This conference will bring together an international community of earthquake scientists andengineers. It will promote an interdisciplinary exchange of ideas and provide everyone with aperspective on the current state-of-art research into the fundamental problems associated withquantifying the effects of the local site geology.The papers presented at the conference will be published on a CD-ROM and distributed to allregistered participants. The papers will also be available through the conference website to thegeneral public.
