Venezuela-Trinidad Crustal and Mantle Structure: A Collaborative Broad Band Seismic Experiment

这项研究是在委内瑞拉东北部和特立尼达安装和运行一个五站便携式宽带阵列的REFTEK/STS-2地震系统，为期一年。目标是成像东加勒比海-南美洲板块边界的地壳和上地幔结构。该项目是委内瑞拉INTEVEP公司地震学小组、特立尼达地震研究单位和卡内基研究所的科学家们共同努力的结果。地震实验的目的是回答有关发震板块边界性质的突出和有争议的问题。地震分析将集中在两大领域：1)是否存在关于委内瑞拉地下残余板块的地震证据；2)通过分析边界相互作用阶段、面波反演以及测量延迟时间和传播时间来确定地壳和上地幔结构。这项研究是国家减少地震危害计划的一个组成部分。

This research is to install and operate for one year a five- station portable broadband array of REFTEK/STS-2 seismic systems in northeastern Venezuela and Trinidad. The goal is to image crustal and upper mantle structures of the eastern Caribbean-South America plate boundary. The project is a collaborative effort between the seismology group at INTEVEP, S.A. (Venezuela), scientists at the Seismic Research Unit, Trinidad, and Carnegie Institution. The purpose of the seismic experiment is to answer outstanding and controversial questions regarding the nature of the seismogenic plate boundary. Seismic analysis will focus on two broad areas: 1) the presence or absence of seismic evidence for a relict slab beneath Venezuela and 2) determination of crustal and upper mantle structure by analysis of boundary interaction phases, surface wave inversion, and measurement of delay times and travel- times. This research is a component of the National Earthquake Hazard Reduction Program.
